Concomitant Gastric And Lung Uptake Of Tc-99m Mdp On Bone Scan In A Patient With Diffuse Large B-Cell Non-Hodgkin’S Lymphoma, Maseeh Uz Zaman, Riffat Hussain Riffat Hussain, Zafar Sajjad, Mansoor Naqvi Mansoor Naqvi, Khalil Khan, Gufran Khan, Zohra I Pirani

Department of Radiology

Extra osseous uptake of Tc-99m Methylene Di Phosphonate (MDP) is not an uncommon finding on skeletal scintigraphy. However, concomitant lung and gastric uptake is a rare presentation. We presented a case report of a young male whose bone scan revealed lung and stomach uptake with a cold lesion over T7 vertebra. CT guided biopsy revealed diffuse large B-cell Non-Hodgkin’s lymphoma. Lung and gastric uptake of Tc-99m MDP on bone scan guides the reporting physician about the soft tissue calcinosis due to hypercalcemia associated with either malignant or non-malignant conditions.


Ultrasonographic Diagnosis Of Placenta Accreta, Shaista Afza, Imrana Masroor, Gulnaz Shafqat Dec 2010

Ultrasonographic Diagnosis Of Placenta Accreta, Shaista Afza, Imrana Masroor, Gulnaz Shafqat

Department of Radiology

Placenta accreta is the abnormal adherence of placenta to myometrium due to defect in decidua basalis. This type of placenta could not remove manually after delivery and lead to severe hemorrhage that may result in emergency cesarean hysterectomy. Prenatal diagnosis of placenta accreta is important because it reduces the fetal and maternal morbidity and mortality as appropriate pre-operative and per operative procedures are possible. Grey scale ultrasonography along with color Doppler imaging proves to be the non invasive, real time, readily available modality with high sensitivity and high positive predictive value.

Spinal Changes In Patients With Ankylosing Spondylitis On Mri: Case Series, Rohana Naqi, Humera Ahsan, Muhammad Azeemuddin Oct 2010

Spinal Changes In Patients With Ankylosing Spondylitis On Mri: Case Series, Rohana Naqi, Humera Ahsan, Muhammad Azeemuddin

Department of Radiology

Magnetic Resonance Imaging appearances are described in three cases of Ankylosing Spondylitis (AS). The different appearances of AS on magnetic resonance imaging are described and their significance in relation to the pathology of this condition is discussed. MRI is increasingly used to detect changes in the spine of patients with AS. Spinal changes associated with spondyloarthritis are florid anterior spondylitis (Romanus lesion), florid discitis (Andersson lesion), ankylosis, insufficiency fractures of the ankylosed spine, syndesmophytes, arthritis of the apophyseal and costovertebral joints and enthesitis of the interspinal ligaments.

Central Nervous System Involvement In Multiple Myeloma, Rohana Naqi, Muhammad Azeemuddin, Humera Ahsan

Department of Radiology

Involvement of the central nervous system by multiple myeloma (MM) is considered to be extremely rare. Magnetic Resonauce Imaging (MRI) is the imaging modality of choice to detect and differentiate myeloma at unusual sites. We present the case of a sixty-year-old man who was a known case of MM. In this case report MRI findings of central nervous system in myeloma lesions are reported.

Department of Radiology

A 54-year-old man presented for radiology with pain and a feeling of fullness in the upper abdomen and an epigastric mass. Ultrasound revealed a large cystic mass with internal echoes, lying posterior and inferior to left lobe of the liver. The gallbladder was thick-walled and contracted, and contained a calculus and echogenic sludge. A cystic structure that produced swirling flow signals on colour Doppler was demonstrated within the gallbladder. The CT scan showed a thickened gallbladder with adjacent inflammation and a 2-cm pseudo-aneurysm in its wall. High-density material was present in the gallbladder lumen, in the extra-hepatic bile ducts and …

Posterior Reversible Encephalopathy Syndrome: A Case Series In Patients With Eclampsia, Rohana Naqi, Humera Ahsan, Muhammad Azeemuddin

Department of Radiology

Posterior Reversible Encephalopathy Syndrome (PRES) refers to a clinicoradiologic entity with characteristic features on neuro-imaging and non-specific symptoms comprising headache, confusion, visual disturbances and seizures. The lesions in PRES are thought to be due to vasogenic oedema, predominantly in the posterior cerebral hemispheres, and are reversible with appropriate management. We report 3 cases of acute PRES who had eclampsia and presented with recurrent episodes of seizures and hypertension. Their MRI scan showed diffuse abnormal signal intensities involving predominantly deep white matter of the occipital lobes. Based on the findings the most probable diagnosis of PRES was suggested. They were started …

Cerebral toxoplasmosis commonly affects patients with advanced HIV immunodeficiency. Toxoplasmosis in patients who are immunocompromised can be severe and debilitating in patients with Central Nervous System (CNS) involvement and the condition may be fatal. We report the case of a 40-year-old man who was a known case of HIV and presented with cerebral toxoplasmosis. His Magnetic Resonance Imaging (MRI) scan showed multiple ring enhancing lesions with extensive surrounding oedema in supratentorial as well as infratentorial region. Lesions were mainly located in the periventricular region as well as at the grey-white matter junction and showed enhancement in the periphery as well …

Department of Radiology

Ewing's sarcoma is the second most common primary tumour of bone in childhood. Less frequently it occurs in soft tissues. Ewing's sarcoma/primitive neuroectodermal tumour (ES/PNET) is an extra ordinarily rare primary tumour in the kidney. Only very few cases of primary renal Ewing's sarcoma have been reported in the literature to date. We present a case of primary right renal Ewing's sarcoma in a 13-year-old girl who was diagnosed as a case of stage IV ES/PNET of kidney with metastases to lung and liver. Right nephrectomy was done followed by adjuvant radiotherapy and chemotherapy with complete response to local and …


Hydatid Disease Of The Breast, Imrana Masroor, M. Azeemuddin, S. Khan, A. Barakzai Apr 2010

Hydatid Disease Of The Breast, Imrana Masroor, M. Azeemuddin, S. Khan, A. Barakzai

Department of Radiology

Cystic hydatid disease is caused by the parasite Echinococcus granulosus. Humans are the accidental intermediate hosts of this organism. Hydatid disease is endemic in countries in which raising sheep and cattle constitutes an important means of livelihood. The most commonly affected organs are the liver and lungs. Involvement of the kidney, bone, brain and other organs is rare. Breast involvement in this disease is also very rare. A case of isolated hydatid cyst of the breast is presented, along with a review of the literature and a discussion on the pertinent clinical and radiological aspects of the disease.
