Background: Continuous kidney replacement therapy (CKRT) is the preferred dialysis modality for critically ill patients with hemodynamic instability. Anticoagulation is often necessary to deliver CKRT effectively and prolong the circuit lifespan. The Kidney Disease Improving Global Outcomes (KDIGO) clinical practice guideline for acute kidney injury 2012 recommends regional citrate administration during CKRT for patients without contraindications to prevent filter clotting. Citrate works by chelating calcium and interfering with the activation of the coagulation cascade. This study evaluated effectiveness and safety of fixed (FIX) versus variable citrate rate (VAR) in critically ill patients receiving CKRT. Methods: This single-center, retrospective study evaluated …

Conference Presentation Abstracts
Acute pulmonary embolism (PE) is a major cause of cardiovascular morbidity and mortality. The clinical outcomes are largely determined by thrombus burden and its hemodynamic impact on the right ventricle (RV). Over the past decade, catheter-directed mechanical thrombectomy has emerged as a promising alternative for systemic thrombolysis for PE management, particularly in patients at high risk for major bleeding. This approach provides rapid mechanical debulking of thrombus without exposure to thrombolytics and has been associated with significant improvements in RV function and pulmonary artery pressures. We present a case of extensive bilateral PE successfully treated with mechanical thrombectomy, highlighting the …

Conference Presentation Abstracts
Introduction: Though often necessary for adequate analgesia after spine surgery, continued opioid use can lead to chronic dependency. The Michigan Spine Surgery Improvement Collaborative (MSSIC) has demonstrated in prior work the promise of utilizing a multi-institutional morphine milliequivalent (MME) cutoff for elective anterior cervical surgery in the opioid naıve population. However, the effect of this cutoff in patients who were already on opioids pre-operatively have not previously been studied. The goal of this study was to evaluate whether changes in prescribing patterns in the opioid naıve population would also translate to the non-naıve populations, and whether the non-naıve population would …

A Rare Convergence: Malignant Thymoma With Pericardial Invasion In A Brca2 Mutation Carrier With A Synchronous Breast Mass, Mahmoud Yacout, Mohammad Chisti
A Rare Convergence: Malignant Thymoma With Pericardial Invasion In A Brca2 Mutation Carrier With A Synchronous Breast Mass, Mahmoud Yacout, Mohammad Chisti
Conference Presentation Abstracts
Introduction Thymomas are rare epithelial tumors of the anterior mediastinum, accounting for < 1% of adult malignancies, with an estimated annual incidence of approximately 0.15 cases per 100,000 persons. Although often indolent, thymomas are malignant by definition and may invade locally, recur, and, less commonly, disseminate. They are classically associated with autoimmune conditions, most notably myasthenia gravis, yet their relationship with hereditary cancer syndromes remains poorly defined. Germline BRCA2 mutations are well established in the pathogenesis of breast, ovarian, pancreatic, prostate, and other malignancies through impaired homologous recombination DNA repair. However, an association between BRCA2 mutations and thymic epithelial tumors has rarely been reported. We describe an unusual case of invasive malignant thymoma with pericardial invasion in a BRCA2 mutation carrier, discovered concurrently with a synchronous FDG-avid breast mass suspicious for malignancy. Case Presentation An 85-year-old man with a history of CAD, hypertension, GERD, and prior radical prostatectomy presented with several months of unintentional weight loss and chronic diarrhea. During evaluation for recurrent appendicitis, imaging incidentally revealed a large anterior mediastinal mass measuring up to 7.9 cm with irregular margins. FDG-PET demonstrated moderate metabolic activity within the mass (SUVmax 3.8). CT-guided biopsy revealed a thymic epithelial neoplasm consistent with thymoma. There was no clinical evidence of myasthenia gravis. He subsequently underwent partial sternotomy with thymectomy. Pathology demonstrated a 6-cm type B2 thymoma with direct pericardial invasion, positive surgical margins (R1), and no regional lymph node involvement (pN0), consistent with pT2 stage III disease by the Masaoka–Koga system. Given high-risk features, adjuvant radiation therapy was initiated, with planned surveillance using PET imaging and circulating tumor DNA monitoring. Concurrent PET imaging identified a palpable FDG-avid right breast mass. Genetic testing revealed a pathogenic germline BRCA2 mutation. The breast lesion is currently undergoing diagnostic biopsy and surgical evaluation. Discussion Thymomas are malignant neoplasms with a predilection for local invasion. Type B2 thymomas carry a higher risk of recurrence, particularly in the presence of pericardial invasion or incomplete resection. Complete surgical excision remains the cornerstone of management, while postoperative radiotherapy is recommended in invasive or R1 disease to reduce locoregional recurrence. The coexistence of invasive thymoma and a germline BRCA2 mutation is exceedingly rare and raises questions regarding shared oncogenic mechanisms. While thymic epithelial tumors are not classically associated with BRCA mutations, DNA repair defects may contribute to tumorigenesis in rare malignancies. The presence of a synchronous FDG-avid breast mass in a male BRCA2 carrier further underscores the importance of comprehensive oncologic and genetic evaluation and highlights the need for multidisciplinary management in complex hereditary cancer presentations. Conclusion We report a rare case of malignant type B2 thymoma with pericardial invasion in a BRCA2 mutation carrier, identified alongside a synchronous breast mass suspicious for malignancy. This case highlights the potential intersection between thymic epithelial tumors and hereditary cancer syndromes, reinforces the importance of genetic evaluation in patients with multiple malignancies, and underscores the need for long‑term multidisciplinary surveillance. Further investigation is warranted to elucidate any causal relationship between BRCA‑mediated DNA repair dysfunction and thymoma development.

Conference Presentation Abstracts
IgG4-related aortitis is a rare manifestation of IgG4-related disease and can closely mimic acute aortic syndromes, including intramural hematoma (IMH), on imaging. Isolated involvement of the descending thoracic aorta is particularly uncommon, and misdiagnosis may lead to unnecessary surgical or endovascular intervention. A 68-year-old man with extensive cardiovascular disease, including prior coronary artery bypass grafting, recent percutaneous coronary intervention with drug-eluting stent placement, permanent pacemaker implantation for complete heart block, and recent pulmonary embolism, presented with three days of chest pain, shortness of breath, and left lower quadrant abdominal pain. At presentation, he was receiving apixaban, aspirin, and clopidogrel. Computed …

Conference Presentation Abstracts
Background: Nonclassic congenital adrenal hyperplasia (NCCAH) caused by 21-hydroxylase deficiency is generally a milder variant of congenital adrenal hyperplasia characterized by partial enzyme activity and variable increases in adrenal androgen levels. Patients presenting with such a condition may present in adolescence or adulthood with symptoms such as acne, hirsutism, irregular menses, and infertility. These symptoms often overlap with those of Polycystic Ovary Syndrome (PCOS), creating challenges in differentiation and management. It is critical to differentiate between PCOS and NCCAH in females of reproductive age, as hyperandrogenism treatment depends on the underlying cause, such as adrenal, ovarian, or a combination of …

Spontaneous Coronary Artery Dissection In Postpartum: A Hidden Cause Of Maternal Myocardial Infarction, Riya Chhabra, Brian Renard
Conference Presentation Abstracts
Spontaneous coronary artery dissection (SCAD) is a tear in the coronary artery lining which decreases blood flow to the heart. SCAD is the leading cause of myocardial infarction in young to middle aged women, especially during and after pregnancy. While SCAD is often managed conservatively, patients are prone to complications like cardiomyopathy. This case underscores the importance of considering SCAD as a differential for postpartum women with chest pain. Furthermore, this case highlights the diagnosis and management of an atypical stress-induced cardiomyopathy with global hypokinesis following postpartum SCAD. A 37-year-old female postpartum for five weeks presented to our hospital with …

Conference Presentation Abstracts
Osteoid osteoma is a benign osteogenic tumor that accounts for approximately 10% of all benign bone tumors and predominantly affects adolescents and young adults. It classically presents with nocturnal pain that responds dramatically to nonsteroidal anti-inflammatory drugs, a feature attributed to increased prostaglandin production within the nidus. The femur and tibia are most commonly involved, whereas upper extremity lesions are relatively uncommon. A 19-year-old male presented with nearly two years of chronic, progressive left lateral elbow pain and left wrist weakness. The pain was nocturnal, radiated along the left arm, and was markedly relieved by nonsteroidal antiinflammatory drugs. He was …

Conference Presentation Abstracts
Introduction: Postoperative ileus (POI) is an infrequent but impactful complication following lumbar spine procedures. While well-characterized in abdominal surgery, spine-specific data remain limited, particularly regarding modifiable risk factors. Materials and Methods: We analyzed 41,164 patients who underwent elective lumbar spine surgery between 2018 and 2023 using the Michigan Spine Surgery Improvement Collaborative (MSSIC) registry. Multivariable generalized estimating equation models were used to identify independent risk factors for POI. We also evaluated the association between POI and postoperative outcomes, including patient-reported outcome measures (PROMs). Results: POI occurred in 1.1% of patients (n = 447). Independent risk factors included older age (RR …

Conference Presentation Abstracts
Introduction: Chronic opioid dependency in spine surgery is an ongoing concern given the ongoing opioid epidemic. We have previously reported on our cohort of opioid-naıve patients, however the literature has shown that patients with opioid use at baseline are at higher risk of less favorable outcomes. Starting in 2022, MSSIC instituted state-wide prescribing guidelines for opioid naıve patients undergoing one- or two-level lumbar decompression surgery (laminectomy, laminotomy, foraminotomy, microdiscectomy) with performance goals of 80% compliance. The goal of this study was to evaluate whether there would be a form of a “halo” effect on prescribing patterns for patients with baseline …

Conference Presentation Abstracts
Fibrillary glomerulonephritis (FGN) is a rare primary glomerular disease characterized by the organized deposition of nonamyloid, randomly arranged fibrils within the mesangium and glomerular basement membrane. While FGN is frequently associated with malignancies and chronic infections, its association with the autoimmune spectrum is emerging as a critical clinical entity. Specifically, the relationship between DNAJB9-positive FGN and discoid lupus erythematosus (DLE) is exceedingly rare, as renal manifestations in lupus patients are typically attributed to immune-complex-mediated lupus nephritis. We present the case of a 67-year-old female with a longstanding history of DLE, manifesting as cutaneous lesions on the extremities and scalp with …

Conference Presentation Abstracts
Introduction: The American Diabetes Association (ADA) recognizes diabetic ketoacidosis (DKA) and hyperglycemic hyperosmolar state (HHS) as life-threatening hyperglycemic emergencies that can overlap clinically; approximately 10% of presentations are described as mixed DKA–HHS. Because current guidelines do not define a single “mixed” category, overlap is best understood as concurrent fulfillment of key elements of both syndromes: DKA-type anion-gap metabolic acidosis with ketonemia or ketonuria, together with HHS-type severe hyperglycemia, hyperosmolality, and dehydration. We report an extreme HHS presentation (glucose >2,100 mg/dL) with limited DKA overlap. Case Description: A 34-year-old woman with longstanding type 1 diabetes mellitus managed with an insulin pump, …

Conference Presentation Abstracts
Introduction- Anaplastic thyroid carcinoma (ATC) is a highly aggressive malignancy constituting about 1% of all the thyroid neoplasms. It has poor prognosis with median survival of around 3 to 6 months. Recent advancements with targeted therapies have improved the survival outcome in these patients. We report a case of anaplastic transformation of papillary thyroid cancer with BRAF V600E mutation who responded to targeted therapy. Case presentation- A 54 year old male presented with a palpable left sided mass. Labs were unremarkable but imaging with contrast enhanced CT scan showed a 3 cm left thyroid nodule with bilateral cervical lymphadenopathy. Biopsy …

Conference Presentation Abstracts
Hepatitis B virus (HBV) reactivation remains a critical concern in immunosuppressed oncology and hematopoietic stem cell transplant (HSCT) patients, yet the optimal duration of antiviral prophylaxis is unresolved. Current guidelines recommend 12–18 months of prophylaxis after HSCT or B-cell depleting therapy for patients who are isolated anti-HBc positive, based on documented cases of late reactivation beyond the traditional 12-month threshold. However, these recommendations largely derive from studies in HBsAg-positive patients or those receiving rituximab-containing regimens, with limited data addressing the broader range of high-risk scenarios encountered in practice. We present two vignettes highlighting this gap. Patient 1 is a 60-year-old …
