摘要:
A 17-year-old boy underwent a radionuclide scan for testicular torsion. The scan demonstrated a cold defect with a warm ring, indicating a “missed” testicular torsion. Operative findings, however, demonstrated epididymitis. A false-positive radionuclide study is described in a patient with epididymitis and the literature of scintigraphy in testicular torsion is reviewed.

摘要:
Hemangiomas are congenital vascular tumors frequently referred for Tc-99m RBC imaging. A case of soft tissue cavernous hemangioma located in the right side of the face and neck is presented. The importance of the Valsalva maneuver in outlining this lesion is described, and a brief review of the literature is presented.

摘要:
Radionuclide cholescintigraphy provides useful information about the dynamics of bile flow through the liver, gallbladder, bile ducts, and intestines. Besides helping to diagnose acute cholecystitis, it may provide other meaningful information to effectively alter the patient's management. Preoperative diagnosis of intestinal obstruction was made on routine cholescintigraphy and was proved subsequently at surgery.

摘要:
An athlete complained of chronic knee pain but had minimal findings on physical examination and initial equivocal radiographs. Subsequent tomograms of the knee suggested a patella stress fracture. Three-phase bone imaging confirmed a stress fracture of the inferior pole of the patella.

摘要:
In an effort to detect extrapulmonary sites of radiogallium accumulation in cases of sarcoidosis, 145 separate Ga-67 citrate studies of 114 patients with biopsy-proven sarcoidosis were examined. The most characteristic extrapulmonary radiogallium uptake pattern was the “panda sign” in 47 patients (41%). The most common site of prominent extrapulmonary radiogallium uptake was the lacrimal glands in 101 patients (88%). Second most common was activity in one or more superficial lymph node regions such as the cervical, axillary, femoral, or inguinal in 19 patients (17%). Other extrapulmonary sites included breast uptake in 6 out of 80 women (8%), prominent splenic and nasal uptake in 9 (8%) patients, periportal accumulation in 7 (6%), and cutaneous/subcutaneous activity in 4 (4%). Because many of these individuals were receiving corticosteroids, the natural (untreated) prevalence of extrapulmonary findings may be even higher. Although the sensitivity and specificity of extrapulmonary radiogallium accumulation has still to be determined, many of the sites may be accessible to biopsy both for diagnostic purposes and to follow the effects of medications. It is therefore suggested that whole-body imaging be performed when radiogallium is administered to patients with suspected or known sarcoidosis.

摘要:
Six patients who had been treated with diethylstibestrol (DES) for prostatic cancer had symmetrical breast uptake of Ga-67. Of these patients, five proved to have DES-induced gynecomastia. The minimum dose and administration period of DES required for Ga-67 uptake in gynecomastia is discussed.

摘要:
A 5-year-old girl with fever and tenderness in her left wrist and right ankle was hospitalized. Bone scanning and Tc-99m labeled leukocyte imaging showed increased uptake in these joints and also in her left knee. These radionuclide methods helped determine the diagnosis and were superior to plain radiography and CT scanning. Uptake was greater on leukocyte imaging than it was on the bone scan. The patient had infectious polyarthritis caused byHaemophilus influenzae,which is a very rare cause of acute polyarthritis in children older than 2 years. The patient fully recovered with antibiotic therapy, and no surgical procedure was needed.

摘要:
Myocardial dysfunction in 14 patients with Duchenne's muscular dystrophy (DMD) was evaluated by Tc-99m HSA multigated radionuclide ventriculography (MGRV). Follow- up studies were performed on eight patients for 5 years. Left ventricular ejection fraction and standard deviation of the phase angle were abnormal in all patients older than 15 years. Hypokinetic changes and phase delay were recognizable in most patients older than 17 years. Peak filling rate decreased in patients older than 17 years. MGRV was considered an effective method for evaluating serial changes in cardiomyopathy of patients with DMD.

摘要:
This report discusses the clinical significance of bilateral parietal abnormalities on I-123 IMP SPECT imaging in 158 patients with cerebral disorders. This pattern was seen in 15 out of 21 patients with Alzheimer's disease; it was also seen in 4 out of 5 patients with Parkinson's disease with dementia, in 3 out of 17 patients with vascular dementia, in 1 out of 36 patients with cerebral infarction without dementia, in 1 out of 2 patients with hypoglycemia, and in 1 out of 2 patients with CO intoxication. Detection of bilateral parietal abnormalities is a useful finding in the diagnosis of Alzheimer's disease, but one should keep in mind that other cerebral disorders may also show a similar pattern with I-123 IMP SPECT imaging.

摘要:
The carotid body paraganglioma is a rare tumor that arises from the autonomic nervous chemoreceptor. It can be diagnosed by contrast angiography. A patient in whom a carotid body chemodectoma was imaged with ln-111 labeled monoclonal anticarcinoembryonic antigen (anti- CEA) antibodies is described. There was marked accumulation of the antibody into the tumor but little blood pool activity at 25 hours. The removed tumor, which was examined immunohistochemically, was positive for vimentin, GFAP, NF 68, SYP, and S-100; and negative for CEA, desmin, and cytokeratin. The tumor was a paraganglioma that accumulated antibody with nonspecific mechanism of uptake.
