Role Of Stereotactic Radiosurgery In The Treatment Of Acromegaly, Komal Naeem, Aneela Darbar, Muhammad Shahzad Shamim

Section of Neurosurgery

Acromegaly is a rare, indolent disease due to overproduction of growth hormone. Surgery is identified as primary treatment, but has its limitation, thus frequently requiring alternate treatment options as adjunct to surgery. Stereotactic radiosurgery (SRS) has been used as adjuvant and alternate therapy in patients with inoperable or residual disease; or those not fit for surgery. It has shown reasonable results for treating macroadenoma and tumours invading cavernous sinuses with significant reduction in tumour size and durable endocrinological remission. Factors favouring better outcomes include time from last resection to SRS, older age, peri-procedural withdrawal of medication, higher margin and maximum …

Role Of Palliative Csf Diversion In Patients With Intracranial Metastatic Disease And Symptomatic Hydrocephalus, Farhan A. Mirza, Muhammad Shahzad Shamim Sep 2018

Role Of Palliative Csf Diversion In Patients With Intracranial Metastatic Disease And Symptomatic Hydrocephalus, Farhan A. Mirza, Muhammad Shahzad Shamim

Section of Neurosurgery

Hydrocephalus, unless treated, is one of the terminal manifestations of intracranial metastatic disease. Single lesions causing obstructive hydrocephalus are amenable to surgical resection, but in the setting of multiple lesions and communicating hydrocephalus from leptomeningeal disease, the approach to treatment is much less defined. The use of endoscopic third ventriculostomy (ETV) and ventriculoperitoneal shunting (VPS) has been described, but data is limited. In this review, we summarize the sparse data available in literature describing the use of CSF diversion for patients with metastatic disease presenting with hydrocephalus and neurological decline.

Simpson Grading As Predictor Of Meningioma Recurrence, Ayesha Quddusi, Muhammad Shahzad Shamim

Section of Neurosurgery

Meningimas are one of the commonest primary brain tumours and the commonest extra-axial primary brain tumour. Despite better understanding of the molecular pathogenesis of the tumours, surgical excision remains the treatment of choice, and in a large proportion of cases, complete excision is curative. Simpson grading for the extent of resection of meningiomas, was introduced more than six decades ago, and has stood the test of time. With modern technological advancements, however, the relevance of Simpson grading has been questioned. Herein we review the recent literature on the relevance of Simpson grading more than sixty years after its introduction.
