High-resolution CT (HRCT) examinations were performed in 22 patients with temporal bone trauma. The CT findings were correlated with the clinical signs and symptoms, routine head CT findings were also examined. HRCT was able to demonstrate fracture lines, ossicular chain disruptions, facial nerve injuries, and hemotympanums in majority of cases. Associated many severe head injuries (brain contusion etc.) were noted in the routine head CT.
A rara case of tuberculous arthritis of right shoulder was reported. Plain X ray and CT showed bone destruction in humerus and glenoid process and soft tissue swelling with calcification was also demonstrated. T2 weighted images showed extension of abscess clearly. And extension to bone marrow was showed on CT and T1 weighted MR images.
A 72-year-old female who had suffered from lower extremity edema and liver cirrhosis due to Budd-Chiari syndrome with massive thrombus in IVC was treated by PTA and placement of self-expandable metallic stent. Thrombolysis therapy after PTA was very effective. Five months later, she had no clinical symptom due to IVC stenosis.
Three cases of alveolar soft part sarcoma were reported with characteristic MRI findings. On MRI findings, slightly higher signal intensity than muscles on T1 weighted image and remarkably high signal intensity on T2 weighted image were thought to be characteristic of alveolar soft part sarcoma.
A case of dural arteriovenous malformation of the spine was reported. The patient was admitted to our hospital because of paraparesis, and selective angiography revealed dural AVM of spine. Myelo-CT and MR imaging showed abnormal vessels in the spinal canal. After embolization, dural AVM was disappeared.
A hematogenic metastasis to the biceps muscle of right upper arm was reported in a 48-year-old women with recurrent uterine cervical cancer who had undergone radiotherapy. Cancer metastasis to the limb skeletal muscle is very rare. We have not known the similar case report in uterine cervical cancer.
A 51-year-old female was diagnosed as diabetes mellitus and pointed out of the abnormal data on CA 19-9. Computed tomography (CT) demonstrated the absence of pancreatic body and tail, and showed gall stone and thickening of the gallbladder wall. So we diagnosed this case as aplasia of the pancreatic body and tail, without operation. This is 59th case in Japan.
We retrospectively evaluated preoperative film- and xeromammography of 23 cases with breast cancers, and compared with postoperative specimen radiography to assess tumor delineation and microcalcification detectability. In tumor detection and margin delineation, film mammography was superior to xeromammography, and in microcalcification, film mammography was equal to xeromammography. These results had a effect on the diagnosis of breast cancers.
