B-Cell Lymphoma Of The Brainstem With Central Neurogenic Hyperventilation, S. Ather Enam, Rushna Ali

Section of Neurosurgery

Non-Hodgkin's lymphoma of the brainstem is a rare entity. Central Neurogenic Hyperventilation (CNH), an associated manifestation of this disease, is an even rarer event. We report a case of an immunocompetent individual who presented to us with tachypnea and facial nerve palsy. Neuroimaging showed a Cerebellopontine angle tumour which on histopathology showed feature consistent with a Non-Hodgkin's B-Cell Lymphoma. The patient went on to develop severe respiratory alkalosis with findings consistent with CNH. Chemotherapy with Methotrexate was started and high dose Dexamethasone was added to the regimen a month later. Radiologically, the tumour size decreased by 50% but the patient's …

Cranial Reconstruction After Decompressive Craniectomy: Prediction Of Complications Using Fuzzy Logic, Saniya Siraj Godil, Muhammad Shahzad Shamim, Ather Enam, Uvais Qidwai, Mohsin Qadeer, Zain A. Sobani

Section of Neurosurgery

Introduction: Cranial reconstruction after decompressive craniectomy (DC) has been shown to be associated with a relatively high complication rate (16.4%-34%) compared with standard neurosurgical procedures (2%-5%). Most studies that have previously attempted to formulate a multivariate model for identifying factors predictive of postoperative complications of cranioplasty either were unsuccessful or yielded conflicting results. Therefore, fuzzy logic-based fuzzy inference system (FIS), which has proven to be a useful tool for risk prediction in medical and surgical conditions, was used in this study to identify predictors of complications of cranioplasty.
Methods: A retrospective chart review of all the patients who underwent DC …

Pediatric Traumatic Putamenal Strokes: Mechanisms And Prognosis, Zain A. Sobani, Arshad Ali Apr 2011

Pediatric Traumatic Putamenal Strokes: Mechanisms And Prognosis, Zain A. Sobani, Arshad Ali

Section of Neurosurgery

Background: Studies have shown that nearly 3% of closed head injuries result in basal ganglia hemorrhages and that this may be a more frequent occurrence in pediatric patients. Various mechanisms based on shearing forces have been implicated in the injury; however, the underlying mechanism leading to the increased incidence in pediatric patients has not been well described. Angiographic data suggest that putamenal perforators in children are more severely stretched at acute angles compared to those in adults, which may be a contributing factor to the increased incidence.
Case description: We discuss a series of five relatively benign cases of traumatic …

Intracerebral Migration Of Stray Bullet Leading To Sudden And Fatal Worsening, Manzar Hussain, Muhammad Ehsan Bari

Section of Neurosurgery

Gunshot wounds to the cranium are one of the leading cause of death and disability in young adults. Stray bullets are also being increasingly seen in clinical setting. We report a case of a 14-year-old boy who sustained a stray bullet to the cranium during election festivities. He arrived at the health care facility institution nearly 24 hours after the event in good neurological condition. He remained neurologically stable for about 8 hours after his presentation and later on deteriorated due to intracranial bullet migration. This required immediate bifrontal decompressive craniotomy along with right frontal lobectomy. However, the patient could …
