Gastric Gastrointestinal Stromal Tumor Incidentally Detected With Meckel Scintigraphy.

A 17-year-old boy presented with fatigue, hypoxia, palpitations, and anemia (hemoglobin 3.5 g/dL). The search for the etiology of the bleeding began with a Meckel scan.

Bone Scintigraphic Findings in MRSA Osteomyelitis.

Methicillin-resistant Staphylococcus aureus osteomyelitis is a severe form of infection characterized by multifocal or multiple segmental osseous involvement and subperiosteal abscess formation with increased frequency of extraosseous complications including pyomyositis, septic thrombus, and septic arthritis. Bone scan showed long segment and/or multifocal involvement in 4 of 5 patients with areas of abnormal increased and decreased uptake. The clinical presentations included limp and/or pain.

Thoraco-abdominal enteric duplication cyst in association with neurenteric cyst, axial skeletal anomalies, and malrotation.

We report a case of a 2-year old boy with cervicothoracic deformity with vertebral rib anomalies, neurenteric cyst, separate thoracoabominal enteric duplication cyst, concurrent intestinal malrotation, and dextroposition of the heart. This combination of abnormalities is very rare. When these lesions are suspected, the patient must be investigated carefully.

Recurrent idiopathic tumoral calcinosis in a child postoperatively.

Tumoral calcinosis is an uncommon disease characterized by the deposition of calcium salts and crystals in the periarticular soft tissues. It is almost entirely a disease of adults. Histological and radiologically, however, features of this condition are identical regardless of age.

Nuclear Medicine in Pediatric Musculoskeletal Imaging.

The pediatric skeleton is a dynamic structure. Bone scintigraphy depends on bone metabolism and therefore is particularly applicable to changes occurring in the physes (growth-plates). A knowledge of the physiologic changes in the growing skeleton as well as the disease processes affecting the different pediatric age brackets are necessary to accurately solve clinical diagnostic problems with bone scintigraphy.
