Changes in Radiosensitivity to Gamma-Rays of Lymphocytes from Hyperthyroid Patients Treated with I-131.

This study investigated the peripheral blood lymphocytes (PBL) response to a dose of γ-rays in patients treated with radioiodine (I-131) for hyperthyroidism vs. healthy controls, to gain information about the individual lymphocytes' radio-sensitivity. Blood samples were taken from 18 patients and 10 healthy donors.

A case of metastatic struma ovarii treated with 131I therapy: focus on preservation of fertility and selected review of the literature.

Struma ovarii is a rare monodermal ovarian teratoma composed predominantly of mature thyroid tissue. We describe herein the case of a 22-year-old woman who underwent a right salpingo-oophorectomy for struma ovarii at the age of 12 years, who was admitted 8 years later with signs and symptoms of a left pelvic tumor. Laparoscopy detected a left ovarian endometriotic cyst and multiple nodules on the pelvic peritoneum, right lateral abdominal wall, diaphragm, vesical plica and liver.

Combined diagnostic imaging in a patient with suspected biliary atresia.

The case of a newborn infant of 40 days of age with persistent jaundice and blood chemistry values suggestive of cholestasis is discussed. Liver and bile duct US documented missed visualization of the gallbladder. In the suspicion of biliary atresia, hepatobiliary scintigraphy was performed; it showed preserved hepatocyte function, missed visualization of the gallbladder and absence of intestinal bile flow which confirmed the diagnostic hypothesis.

Role of myocardial gated SPECT scintigraphy in the clinical suspicion of ischemic cardiomyopathy: discussion of an unusual case.

The case of a 72-year-old patient affected by myasthenia gravis under pyridostigmine therapy, admitted to the hospital for the onset of oppressive thoracic pain associated with mild enzyme increase, electrocardiographic and echocardiographic disorders, is discussed. Dypiridamole/gated SPECT perfusion scintigraphy at rest evidenced reduced coronary reserve at the level of the lateral wall with apical akinesia and normokinesia of mediobasal left ventricle. On coronarography, coronary arteries were free of significant stenoses and left ventricular apical akinesia.
