A Transgender Woman with Testicular Cancer: A New Twist on an Old Problem.

We present the case of a transgender woman who developed rising testosterone and estradiol levels while on feminizing hormones. After months of uncertainty about the cause of her elevated hormone levels, her physician found a large testicular mass on examination. The patient was diagnosed with a rare virilizing form of testicular cancer.

Streptococcus bovis meningitis in an infant.

Streptococcus bovis is a nonenterococcal, group D streptococcus which has been identified as a causative agent for serious human infections, including endocarditis, bacteremia, and septic arthritis. Several cases of adult S. bovis meningitis have been reported, usually in association with underlying disease.

SPECT and lumbar MRI in back pain with emphasis on changes in end plates in association with disc degeneration.

Over a two-year period, 48 sequential patients were selected because they showed type I or II end plate changes on magnetic resonance imaging (MRI) and/or had positive single-photon emission computerized tomography (SPECT) scan in the area of disc degeneration. They were selected out of a large group of patients who were being evaluated by MRI and SPECT scan for low back pain. In this group of 48 patients, 47 had positive SPECT scans at the disc space, which on MRI indicates degenerative disc disease.

SPECT evaluation of lumbar spondylolysis and spondylolisthesis.

Fifty patients with back pain and radiologically diagnosed spondylolysis were evaluated by a single-photon emission computed tomography (SPECT bone scanning). These patients were separated into three groups according to the degree of spondylolisthesis accompanying the spondylolysis. The data obtained from the study indicate that in acute spondylolysis, the SPECT scan is positive at the pars interarticularis.

SPECT evaluation of unilateral spondylolysis.

Three patients with unilateral spondylolysis were evaluated with SPECT and Lumbar CT. All three cases had positive scans. However, the SPECT images were unique to each case.

Bone SPECT in patients with persistent back pain after lumbar spine surgery.

Twenty-five patients with persistent pain after lumbar spine surgery for pain were evaluated by single photon emission computed tomography (SPECT) bone scanning. The patients were divided into three groups, depending on the type of surgery performed. The data obtained indicates that lumbar spine SPECT is most useful in conditions where there is the greatest likelihood of instability.
