Urachal-sigmoid fistula associated with diverticular disease.

Background: Urachal anomalies rarely present in adulthood. We report the second known case of urachal-sigmoid fistula associated with diverticular disease.

Method: We performed a case report and literature review.

Primary spinal leptomeningeal astrocytoma.

This autopsy case report describes a clinically aggressive, histologically well-differentiated, diffuse, primary leptomeningeal astrocytoma. This rare tumour produced a meningitic clinical picture associated with hydrocephalus, focal spinal cord necrosis, and signs of spinal and cranial nerve root irritation. Despite the microscopic features, death occurred approximately 7 weeks after the first meningeal symptoms.
