ABSTRACT
Transcatheter arterial chemoembolization (TACE) is one of the most common palliative treatment modalities for patients with advanced hepatocellular carcinoma (HCC). TACE is an invasive procedure associated with several potential complications of varying severity. A pulmonary embolism after TACE for HCC is a rare complication. We report a case of pulmonary Lipiodol embolism after a third TACE resulting in death.

Systemic manifestation of tuberculosis is common, but tuberculous biliary obstruction of the pancreas and a colon adenocarcinoma with combined colonic tuberculosis is an uncommon disorder. We encountered a case of the above condition in 63-year-old male that was admitted to our hospital because of fever, diffuse abdominal pain and rigidity. Abdominal computed tomography showed biliary and pancreatic duct dilatation with left colonic wall thickening and surrounding peritoneal infiltration. Emergency segmental resection of the descending colon with intraoperative T-tube choledochostomy was performed due to the colon mass and biliary obstruction. A colonofiberoscopy was performed for low abdominal pain and hematochezia at 12 days after surgery. It showed multiple colonic ulcerations with a partial stricture. A colonic biopsy showed granulomatous inflammation with acid-fast bacilli. The cause of the biliary obstruction was also revealed as pancreatic tuberculosis by an intraoperative pancreatic and mesenteric biopsy. The patient improved after antituberculous treatment and the patient has been in good health until the last outpatient follow-up visit.

A ganglion cyst is a tumor-like lesion that contains mucous or myxoid material in the fibrous capsule. We report a case of ganglion cyst located in the lumbar anterior epidural space and causing lumbar radiculopathy. Computed tomography and magnetic resonance imaging revealed the cyst as a cystic lesion with wall en-hancement. Myelography showed that it was not filled with contrast medium and not connected with the dura, nerve root, or facet joint.

Spontaneous herniation of the spinal cord is a rare disease entity in which spinal cord substance is herniated through a previously uninjured and/or untouched dura. It is a cause of myelopathy that is treatable but difficult to diagnose. We report the CT and MR findings of a case of spontaneous thoracic spinal cord herniation manifesting as ventrolateral protrusion of thoracic spinal cord through a dural defect.

A 27 year old man presented with complaints of headache and visual disturbance, first noted six months earlier. Simple radiographs of skull sellar widening and calcification. Brain CT revealed a 3 X3 X4 cm-sized sellar suprasellar mass with heavy calcification. T1-weighted MR images showed that the signal intensity of the mass was slightly lower than that of the gray matter, while T2-weighted images showed heterogeneous high signal intensity with central low-signal-intensity foci, suggesting calcification After contrast infusion, enhancement was irregular. Surgery revealed a 4 X5 cm sized, well-demarcated, lobulated mass adhering to the meninges. Papillary-type pituitary adenoma was histologically confirmed. We report the CT and MR findings of atypical pituitary adenoma with extensive internal calcification mimicking craniopharyngioma.

In the evaluation of vascular lesions, MR can be used to distinguish slow- from high-flow lesions on the basis of the observed spin-echo MR signal characteristics. MR imaging can also represent features of the static tissues of the vascular lesions that are composed of fibrofatty components, as well as thromboses, phleboliths and muscle atrophy. This paper illustrates the MR findings of various vascular lesions, correlating them with the pathologic specimen and emphasizing on the static tissues.
