Urachal Adenocarcinoma: A Case Report of a Rare Tumor.

Urachal adenocarcinoma is a rare and aggressive bladder cancer involving the urachus, an embryological fibrous remnant of the allantois extending from the bladder to the umbilicus. Usually discovered in the advanced stages, this cancer can commonly present with a poor prognosis. We report a case of a 34-year-old male patient with an unremarkable medical history who presented to the emergency department with severe, sudden onset, sharp abdominal pain.

Recurrence of atypical and anaplastic intracranial Meningiomas: A meta-analysis of risk factors.

Background: The predictive role of multiple risk factors for intracranial atypical and anaplastic meningioma recurrence is convoluted. This meta-analysis assessed the predictive value of selected factors for recurrence in these Meningiomas.

Methods: Studies encompassing risk factor data including gross total resection (GTR), subtotal resection (STR), post-op radiotherapy, Ki-67 % index >3 %, and location were searched for in PubMed, Embase, and Web of Science, and thereafter analyzed using robust Bayesian meta-analysis.
