Diffuse alveolar hemorrhage: a rare manifestation of trauma.

Objective: Fat emboli syndrome (FES) is a disorder associated with both acute lung injury and acute respiratory distress syndrome. Both FES and diffuse alveolar hemorrhage (DAH) are bronchoscopically definable entities that may share a common etiology. We conducted a chart review analysis to examine the relationship between FES and DAH.

Primary anaplastic glio-neuronal tumor of the pineal gland: a new type of pineal neoplasm?

Background: Tumors of the pineal gland are relatively rare. Most are solid, infiltrative lesions characterized by either germ cell, glial, or pineal parenchymal origin. To our knowledge, none have been described that contain an admixture of both anaplastic glial and neuronal elements.

Role of proton magnetic resonance spectroscopy in the diagnosis of gliomatosis cerebri: a unique pattern of normal choline but elevated Myo-inositol metabolite levels.

A patient with histologically proven gliomatosis cerebri presented with a normal choline level but a markedly abnormal elevated myo-inositol level on magnetic resonance (MR) spectroscopy. We describe the case presentation, imaging findings (in particular, the unique MR spectroscopic pattern), and their significance regarding the diagnosis of this relatively rare neoplasm.

Intramedullary spinal cord astrolipoma: case report.

Objective And Importance: Reported is a case of a thoracic intramedullary astrocytoma with a lipomatous component, a so-called astrolipoma. This is the only known case of a single intraspinal astrolipoma in an otherwise healthy patient.

Clinical Presentation: The patient was a 36-year-old woman with dorsal thoracic pain of more than 1 month's duration, mild lower extremity weakness, and incomplete sensory loss to the T10 level.

Computed tomography's ability to predict sacrifice of hypoglossal nerve at resection.

Objective: To assess whether preoperative computed tomography (CT) scan can determine if the hypoglossal nerve (cranial nerve XII) will be sacrificed in floor-of-mouth, oral tongue, and tongue base tumor resections.

Study Design: Retrospective review.

Methods: Patients who underwent resection of floor-of-mouth, oral tongue, and tongue base tumors from 1990 to 1999 were identified.

Primary splenic lymphoma complicated by hematemesis and gastric erosion.

Gastrosplenic fistula resulting from erosion of a primary splenic lymphoma is a rare cause of massive upper gastrointestinal hemorrhage associated with benign peptic ulcer disease, gastric Crohn's disease, gastric adenocarcinoma, and primary gastric and splenic lymphomas. Upper intestinal hemorrhage can be successfully treated with splenic artery embolization, followed by splenectory and gastric resection.
