Brain SPECT Imaging in Complex Psychiatric Cases: An Evidence-Based, Underutilized Tool.

Over the past 20 years brain Single Photon Emission Computed Tomography (SPECT) imaging has developed a substantial, evidence-based foundation and is now recommended by professional societies for numerous indications relevant to psychiatric practice. Unfortunately, SPECT in clinical practice is utilized by only a handful of clinicians. This article presents a rationale for a more widespread use of SPECT in clinical practice for complex cases, and includes seven clinical applications where it may help optimize patient care.

Two diagnostic correlates of dexamethasone nonsuppression in normal weight bulimia.

Evaluations of neuroendocrine abnormalities and possible relationship to major affective disorder in normal weight bulimic women have utilized the Dexamethasone Suppression Test (DST). In our sample of 29 bulimic women, 59% showed DST nonsuppression (DSTNS). Two diagnostic correlates were significant in relation to DSTNS: prior history of anorexia nervosa and current clinical DSM III diagnosis of depression.

Benign retroperitoneal neurilemoma without von Recklinghausen's disease: a rare occurrence.

We describe a rare case of a primary retroperitoneal neurilemoma that was confused initially on ultrasonography and computerized tomography for a renal carcinoma. These tumors vary in vascularity on arteriography, are more often solid than cystic and usually are benign in the absence of von Recklinghausen's disease. The preferred treatment is wide surgical excision.
