INTRODUCTION Splenic tumors are rare and present a diagnostic dilemma. Metastatic carcinoma to the spleen is unusual. Visceral metastases in patients with ovarian cancer represent hematogenous spread of the disease; capsular involvement resulting from serosal and peritoneal seeding is more common. We present a patient with intraparenchymal splenic metastasis from ovarian carcinoma. This case de...

BACKGROUND Neurenteric cysts are congenital cysts of the central nervous system that are believed to be of endodermal origin. In this report we present the unique case of a supratentorial neurenteric cyst that is contained entirely within the brain parenchyma. METHODS A patient presented with an intraparenchymal cystic lesion that was subsequently identified as a neurenteric cyst. This lesion...

We report the case of a 27-year-old female with intraparenchymal leiomyoma of the breast. This case is interesting not only because intraparenchymal leiomyoma of the breast is a rare benign non-epithelial tumor, but also because it is never found in women at such an early age. We explain all the aspects of this case in this report with its radiologic, histopathologic and immunohistochemical fin...

Evidence of cerebrovascular disease at autopsy was compared in 2 groups of men: 186 long-time residents of Hiroshima, Japan, and 253 men of Japanese ancestry long resident in Honolulu, Hawaii. They were 45 to 71 years-of-age at death. Atherosclerosis of the circle of Willis and its major branches, sclerosis of the intraparenchymal arteries and the frequency of cerebral hemorrhage and cerebral i...

We report a case of intraparenchymal pneumocephalus caused by ethmoid sinus osteoma in a 57-year-old man who had suffered from severe allergic rhinitis because of which he had to frequently blow his nose. He was referred to our hospital for headache and mild left hemiparesis. A computed tomography scan revealed a large intraparenchymal air entrapment in the right frontal lobe related to an oste...
