We present a unique case of aggressive osteoblastoma arising from thyroid cartilage. A 52-year-old man presented with a 10 month history of neck discomfort but without frank pain. CT and MR examinations disclosed a well defined mass arising from the thyroid cartilage. This lesion had areas of coarse calcifications and a central area of lucency. The appearance suggested chondrosarcoma. Hemilaryngectomy was performed to remove the mass en bloc. Surgical pathology diagnosed aggressive osteoblastoma arising from thyroid cartilage.

A case is reported of a 31‐year‐old woman who had a copper‐7 IUD inserted two years prior to admission but became pregnant and had a normal delivery a year prior to admission. The IUD had not exited her body during delivery, and she was asymptomatic. Ultrasonography was used to locate the IUD, which was extending through the wall of the uterus. Upon mini‐laparotomy, the IUD was found to be completely outside of the uterus, embedded in the omentum. This represents the first reported case which documents the use of ultrasonographic technology to locate an IUD extending through a uterine wall.

The intraluminal component of symptomatic malignant carcinoid tumors of the small bowel is typically small relative to the extension in the mesentery, and barium examinations are occasionally normal. This case report illustrates the diagnostic value of abdominal ultrasonography in the detection of extraluminal component of a carcinoid tumor.
