We present the case of a 79-year-old female with symptomatic cavernous haemangioma of the liver. The patient had experienced progressive right lateral abdominal pain for years despite increased painkiller use. Surgical resection or transarterial embolisation was not recommended because of the patient's age, cardiovascular comorbidities and large tumour(More)
Mesenteric neurilemmoma is extremely rare. We present a case of a 45-year-old man with mesenteric neurilemmoma, with CT, MRI and angiographic findings. The patient was healthy and had had no symptoms previously. CT and MRI images revealed a 2.2-cm well-defined, soft-tissue mass adjacent to the posterior border of the left lobe of the liver. The tumor mass(More)
A 31-year-old woman with epithelioid sarcoma of the thigh is presented. The patient had had a progressively growing mass in her left thigh for 4 months. Magnetic resonance imaging (MRI) showed a subcutaneous mass with a central area of hypointensity and serpiginous hyperintensity in the peripheral portion. Such findings have not been reported before.(More)
We report computed tomography (CT) findings for a rare case of follicular dendritic cell sarcoma of the greater omentum from a 47-year-old female patient. The tumor presented ash a palpable mass lesion in the umbilical region for the last two months. Multidetector CT scan of the abdomen showed a 14-cm soft-tissue mass with calcification and necrosis within(More)
Early detection and treatment of coronary artery disease (CAD) can reduce incidences of acute myocardial infarction. In this study, we determined the proper use of contributing risk factors and coronary artery calcium score (CACS) when screening asymptomatic patients with coronary arterial stenoses using coronary computed tomography angiography (CCTA). We(More)
Chordomas are rare tumors of notochordal tissue remnants and most frequently affect the sacrum and skull base. We report a case of a 58-year-old woman having cervical chordoma causing related symptoms for 5 years. MRI showed a dumbbell-shape mass with heterogeneous enhancement at C2 and C3 on postcontrast images, mimicking neurogenic tumor. Chordoma should(More)
Osseous hemangiopericytoma is rare. We present a case of a 30-year-old woman with low-back pain with radiation to the left buttock for 1 month. Magnetic resonance imaging (MRI) showed a tumor mass with areas of serpentine signal void pattern in the sacrum suggestive of a vascular tumor. Neither calcifications nor layered blood serum were noted. Histological(More)
We report a case of hepatic perivascular epithelioid cell tumor (PEComa) in a woman who was not a carrier of viral hepatitis and had a normal alpha-fetoprotein (AFP) level. CT scan showed a well-enhanced mass in the arterial-phase followed by early washout in the portal venous-phase in the lateral segment of the liver. Angiography revealed a hypervascular(More)
