Background:Pheochromocytomas are catecholamine secreting tumors of the adrenal medulla chromaffin cells, however, when present extra-adrenally they are called paragangliomas. Paragangliomas rarely produce catecholamine in excess, which is evident by clinical symptoms, urine, and blood biochemistry. Total resection of these tumors can lead to complete clinical and biochemical resolution. This case report presents the clinical features, radiological findings, and neurological outcome in a middle-aged female with a secretory paraganglioma.

Background:Simultaneous presentation of arteriovenous malformation (AVM) and glioblastoma multiforme (GBM) is rarely reported in the literature and needs to be differentiated from “angioglioma”, a highly vascular glioma and other differential diagnosis such as hypervascular glioblastoma. Incorporating critical features of both, malignant glioma and AVM, such lesions lack a standard algorithm for diagnosis and therapy due to their rare incidence as well as their complex radiological and highly individualized clinical presentation.

Background:Symptomatic intratumoral hemorrhage (ITH) in vestibular schwannoma (VS) is rare. A repeated hemorrhage is, therefore, even more exceptional. Repeated ITH has been reported in four cases thus far in English literature. Here, we describe a patient with a Koos grade D VS who presented to our Skull Base team with repeated ITH and an unexpected disease course.

Background:Hydatid disease is a life-threatening parasitic infestation caused by Echinococcus granulosus. Infection with E. granulosus typically results in the formation of hydatid cysts in the liver, lungs, kidney, and spleen. Primary intracranial hydatid cyst disease is extremely rare. Here, we are reporting an unusual case of Echinococcus, where the only identifiable lesion was a hydatid cyst in the brain without liver or lung involvement. We are also providing a description for the surgical technique used to remove the cyst, highlighting the possible surgical pitfalls.
