Fortuitous imaging of a primary adrenocortical carcinoma with Tc-99m HDP.

The importance of evaluating nonfunctional adrenal masses in the right clinical setting is discussed. A 60-year-old man was initially diagnosed of having a localized lung carcinoma. Metastatic work-up showed an adrenal mass that was not deemed to be related to the lung primary. Although biochemical testing revealed that the adrenal mass was nonfunctional, adrenal scintigraphy was not performed. On resection, the lung neoplasm was shown to be a poorly differentiated adenocarcinoma. Radiologic follow-up of the adrenal finding was recommended. A year later, the patient presented with an abdominal mass that was visualized by bone scintigraphy and, on resection, proved to be adrenocortical carcinoma. In retrospect, the lung mass was a metastasis of an adrenocortical carcinoma.

Adenomyosis as seen on blood flow and blood pool imaging during bone scintigraphy.

A 42-year-old woman presented with intermittent low back and left lower extremity pain. The blood flow and blood pool images of bone scintigraphy showed a large focus of increased activity in the right lower abdomen. Computed tomography showed an enlarged uterus displaced to the right side of the pelvis. At surgery, the uterus was found to be involved with adenomyosis. Three-phase bone scintigraphy consisting of blood flow and blood pool images over the anterior pelvis may be a valuable diagnostic aid in the evaluation of lower back or pelvic pain of a woman.
