Progressive Quadriparesis of a Toddler with a Posterior Cranial Fossa Arachnoid Cyst (AC): Illustrative Case Report and Narrative Literature Review.

Background/objectives: Intracranial arachnoid cysts (ACs) may be congenital, primary, or secondary due to trauma. These cysts are benign, contain cerebrospinal fluid (CSF), and are classified based on location, size, and their clinical symptomatology. They are uncommon lesions in children, rarely leading to severe mass-effect neurological symptomatology.

Intrameningioma metastasis: A case-based literature review.

A tumor-to-tumor metastasis inside a meningioma is a rare phenomenon. Malignant neoplasms of the breast and lung are the most common primary tumors. Other sites of origin include prostate, renal and gastric neoplasms.

A comparison of acute hemorrhagic stroke outcomes in 2 populations: the Crete-Boston study.

Background And Purpose: Although corticosteroid use in acute hemorrhagic stroke is not widely adopted, management with intravenous dexamethasone has been standard of care at the University Hospital of Heraklion, Crete with observed outcomes superior to those reported in the literature. To explore this further, we conducted a retrospective, multivariable-adjusted 2-center study.

Methods: We studied 391 acute hemorrhagic stroke cases admitted to the University Hospital of Heraklion, Crete between January 1997 and July 2010 and compared them with 510 acute hemorrhagic stroke cases admitted to Massachusetts General Hospital, Boston, from January 2003 to September 2009.
