Intraductal oncocytic papillary neoplasm (IOPN) of the pancreas is a rare pancreatic tumor. To date, there have been three case reports of IOPN which showed strong positivity on 18F-fluorodeoxyglucose positron emission tomography (FDG-PET), raising the possibility of distinguishing IOPNs from other intraductal papillary mucinous neoplasms (IPMNs) using FDG-PET. However, all three cases had larg...

OBJECTIVES To report an extremely rare case of ovarian borderline mucinous cystic tumor accompanied by low-grade endometrial stromal sarcoma (LGESS) with myxoid change. CASE PRESENTATION A 42-year-old woman complained of lower left abdominal fullness. Her serum carcinoembryonic antigen, cancer antigen (CA) 125, and CA19-9 levels were normal. Magnetic resonance imaging showed a 10-cm cystic ma...

BACKGROUND AND PURPOSE Thyroid carcinoma arising in a thyroglossal duct cyst may be clinically indistinguishable from a benign thyroglossal duct cyst. The preoperative diagnosis of carcinoma, however, can have important implications for surgical planning and postoperative treatment. Our purpose was to describe the CT appearance of thyroglossal duct carcinoma and identify the features that disti...

Neonatal hydrocolpos is a rare condition that involves fluid accumulation in the vagina. On diagnostic imaging, the dilated vagina, along with the compressed uterus, can simulate a mature cystic teratoma with a mural nodule. Herein, we report the case of a newborn girl with congenital hydrocolpos that was caused by an imperforate hymen; the hydrocolpos mimicking a mature cystic teratoma on abdo...

We report a case of middle-aged woman incidentally diagnosed with Takayasu arteritis during the ultrasonography of a thyroid gland nodule. Prominent collaterals of the thyroidal arteries and a thin common carotid artery with mural thickening and deficient intraluminal flow signals were initially depicted on the ultrasonography with color Doppler. Subsequent magnetic resonance angiography and co...

Desmoplastic infantile gangliogliomas (DIG) are rare intracranial tumors that typically occur in infants and involve the cerebral cortex and the leptomeninges. They are usually very large in size and partially cystic. Total resection, if possible, is the treatment of choice, without the need for further adjuvant therapy. We report 2 cases of DIG. In both cases, computed tomography and magnetic ...
