We report a case of scintigraphic detection and localization of a bleeding leiomyosarcoma of the jejunum utilizing Tc-99m labeled red blood cells. Despite conflicting mesenteric arteriograms, the patient underwent surgery based upon the scintigraphic study, resulting in a successful outcome.

We present a case of emphysematous gastritis initially detected with 111In oxine-labeled white blood cell scintigraphy and subsequently confirmed by computed tomography. Early aggressive antibiotic and supportive therapy resulted in a successful clinical outcome.
We present a rare case of septic arthritis of a lumbar facet joint with an associated epidural abscess resulting from Staphylococcus aureus. The infection was initially detected with planar bone scintigraphy and precisely localized with single photon emission computed tomography bone scintigraphy, despite an initially negative radiologic evaluation that included radiographs of the lumbar spine, lumbar myelography, and a postmyelography x-ray computed tomography scan. In the appropriate clinical setting, a bone scan demonstrating unilateral increased activity within the spine should raise the suspicion of inflammatory involvement of the posterior elements.
A case of Salmonella costochondritis developed at a traumatic focus in a 37-yr-old Hispanic male without hemoglobinopathy or systemic disease. Bone scans and gallium scans were initially positive and remained abnormal, despite a variable clinical course and repeatedly negative serology and blood cultures. Scintigraphy was valuable for both detection and monitoring of antibiotic treatment, as well as providing localization for subsequent surgical resection.
A 89-year-old, nursing home female presented with a two-week history of drooling and a hard palpable mass in the region of the larynx. Initial fiberoptic laryngoscopy revealed a hard pinkish-white mass which was felt to represent a tumor. Computed tomography demonstrated swallowed, impacted, complete, mandibular denture. Radiologists should be aware of this problem, particularly in the elderly demented patient.
