Contrast MRI in multiple endocrine neoplasia type 1 (MEN) associated with renal cell carcinoma.

The radiologic work-up of a patient with multiple endocrine neoplasia type 1 (MEN 1) syndrome and multiple endocrine nodules, with coincidental renal cell carcinoma, is described. Parathyroid adenoma was differentiated from multiple thyroid nodules by gadolinium-enhanced MRI. Adrenal enlargement due to a nonfunctioning adenoma and a renal cell carcinoma next to a simple renal cortical cyst were identified by typical signal intensities on T1- (pre- and post-Gd-DPTA) and T2-weighted images. Insulinoma was visualized only retrospectively.

Total ionized serum calcium and parathyroid hormone levels in patients with disseminated coccidioidomycosis.

Twenty-one patients with severe coccidioidomycosis, including eight with osseous lesions, were admitted to the University of California, Davis, Medical Center, during a recent epidemic. Transient mild ionized hypercalcemia occurred in only two patients, and a tendency toward low normal ionized calciums was noted. Parathyroid hormone levels appeared to be appropriate for the ionized calcium in these patients. There were no significant differences in ionized calcium levels of parathyroid hormone levels among patients with and without osseous coccidioidomycosis. We conclude that hypercalcemia is rare in coccidioidomycosis, even with extensive bony involvement.

Immobilization hypercalcemia: a case report and review of the literature.

A 17-year-old girl was immobilized in traction for 3 months and in a spica cast for 6 weeks for fractures of the femur and pelvis. Seven weeks after injury and after her acute renal failure had resolved, serum calcium rose and remained elevated for the duration of her immobilization. Conservative treatment by hydration, diuresis, and later tilttable therapy failed to relieve her hypercalcemia. Only after mobilization did the serum calcium levels return to normal and the symptoms abate. Administration of recently developed medical methods of management of hypercalcemia may have prevented this complication.
