Multiple meningiomas.

A 57-year-old woman with hyperthyroid ophthalmopathy underwent somatostatin receptor scintigraphy with In-111 pentetreotide. She also reported migraine-type headaches over the previous 3 months, without any other obvious neurologic symptoms and signs. The study revealed an increased uptake of the radiopharmaceutical in both periorbital areas and the right lobe of the thyroid gland. Multiple foci of marked tracer uptake were also detected in the right half of the head. A brain MRI scan subsequently revealed multiple lesions consistent with meningiomas on the surface of the right cerebral hemisphere.

Hypersensitivity reactions during hemodialysis related to the use of acetate dialysate. A case report.

A patient developed a hypersensitivity reaction two weeks after being put on hemodialysis with acetate dialysate. The reactions appeared exclusively during hemodialysis and were relieved immediately after its termination. These allergic manifestations disappeared with substitution of bicarbonate for acetate dialysate and reappeared upon rechallenge with acetate dialysate. The rest of the dialysis materials were excluded as possible causes of allergy by scheduled dialysis sessions with varying materials. Acetate dialysate is implicated as the cause of allergy reaction in this case.
