title: Echogenic mobile spherules in a cyst as an ultrasound finding in cystic mediastinal teratoma.
abstract: Mature teratomas are the most common mediastinal germ cell tumor. They are mostly cystic. They are usually asymptomatic and diagnosed incidentally on chest X-ray or CT scan. The diagnosis of teratoma is usually confirmed by CT scan. It shows variable combination of fat, fluid, soft tissue component, and calcification. Ultrasound, a cheap and widely available imaging modality, also provides valuable characteristic appearances of mediastinal teratomas. We present a case of mediastinal cystic teratoma showing characteristic echogenic mobile spherules in the cyst and its brief discussion.
