ABSTRACT
131I is widely used for the treatment of goiter and residual and metastatic thyroid cancer. Uptake of 131I is mainly due to the expression of sodium-iodide symporter in the target tissues. Incidental third space accumulation in the pleural and pericardial cavity can be encountered due to passive diffusion of tracer into these cavities. We present an interesting finding of 131I accumulation in the scrotal hydrocele in a 70-year-old patient with a metastatic classical variant of papillary thyroid carcinoma, who was treated with 200 m Ci of 131I.
ABSTRACT
Tuberculosis (TB) is a common bacterial infection in developing countries. Solid-organ and hematopoietic stem cell transplant recipients are more prone to this infection. Reactivation from previously acquired infection is the most common mode. It has to be ruled out in cases of pyrexia of unknown origin (PUO) before ruling out the other possibilities. We present two cases of incidentally detected TB in the posttransplant patients referred for the evaluation of PUO.
ABSTRACT
Parathyroid hormone (PTH) is a key in maintaining calcium homeostasis. Decreased PTH will result in decreased bone remodeling and increased bone density. The major cause is iatrogenic injury to parathyroid gland. X-ray and dual-energy X-ray absorptiometry are used to identify the skeletal changes. Typical skeletal changes are metaphyseal sclerosis in long bones and sclerosis of vertebrae and pelvic bones. 99mTc methylene diphosphonate scintigraphy is used to identify metabolic bone diseases. There are no typical scan findings in case of hypoparathyroidism. We like to report an interesting image of skeletal scintigraphy in case of hypoparathyroidism.
