Unusual motion detected on real-time sonography inside a glomus tumor in the thigh.

Glomus tumors are rare and many have been reported to have a hypervascular appearance on color or power Doppler sonography. We report a pathologically proven case of superficial glomus tumor within the thigh with no detectable color flow signals on color or power Doppler sonography. In addition, real-time sonography showed spontaneous motions within the tumor, which were not synchronized with vascular or respiratory motions, and misled the presurgical diagnosis of a suspected parasite in a patient who had direct contact with multiple animal species.

Radiation pneumonitis following yttrium-90 radioembolization: case report and literature review.

Radiation-induced pneumonitis (RP) is a rare complication of radioembolization with yttrium-90 ((90)Y) microspheres. The present report describes a case of RP in a patient with liver metastases from a gastrointestinal stromal tumor after radioembolization with (90)Y glass microspheres. This patient developed clinical, functional, and radiographic findings consistent with RP, with near-complete pulmonary parenchymal recovery and no clinical evidence of relapse or progressive decline in pulmonary function over a 9-month period.
