Perinephric hemorrhage secondary to adrenal myelolipoma. Case report.

Spontaneous perinephric hemorrhage has been described as occurring secondary to a number of primary renal abnormalities, but rarely from other causes. We describe the computed tomography (CT) and ultrasound findings of this event resulting from hemorrhage from an adrenal myelolipoma.

Diagnosing osteomyelitis in Gaucher's disease. Observations on two cases.

Bone scans in two patients with Gaucher's disease were reported as consistent with Gaucher's-associated osseous crises. A bone-radiogallium subtraction study was also initially negative in each individual (although it later became positive in one). At surgery both patients were seen to have osteomyelitis.

Elevation of serum prostaglandin E levels following electrical stimulation of the midbrain.

Serum prostaglandin E (PGE) levels were measured in rats immediately following electrical stimulation of the mesencephalic periaqueductal gray (PAG) region and the nucleus raphe magnus (NRM) and compared to controls. An additional group received aspirin prior to PAG stimulation. A significant increase in serum PGE levels was found after stimulation of the PAG, but not the NRM.
