A 28-year-old woman presented with a rare case of chest-wall teratoma. Computed tomography of a cystic lesion located in the anterior chest wall revealed a hyperdense object with the appearance of a tooth. The cystic mass was totally excised via a chest-wall incision without thoracotomy. Pathologic examination showed a benign teratoma containing an immature tooth.
We report a patient with a frontal bone osteoma showing the classical findings of haemangioma. A craniectomy and total tumour excision was carried out.
Intraspinal epidermoid tumors are rare and the intramedullary location is quite uncommon. In this report, a 48-year-old patient with intramedullary epidermoid cyst mimicking a cauda equina ependymoma is presented and diagnostic failure of conventional myelography and Myelo-CT is questioned and related literature is reviewed.
Twenty-one patients with epiphora were examined by conventional dacryocystography, using Lipiodol as a contrast medium, and CT dacryocystography, using a water soluble contrast medium. In the latter, the material was not introduced under pressure but three or four drops were administered, providing a physiological method of investigation. Subsequently, CT dacryocystography provides functional information about lacrimal disorders and is easy to use.
A fifty-year old woman, gravida 17, para 17, presented with profuse vaginal bleeding following curettage in another hospital. At emergency laparotomy total abdominal hysterectomy and bilateral salpingo-oophorectomy was performed because of intractable hemorrhage. Histopathologic examination revealed endocervical placentation and adenomyosis uteri. The case is presented due to its rarity and possible predisposing factors are discussed.
We describe a rare case of vertebral artery duplication in a patient with vertigo, weakness, and nausea. A color Doppler examination revealed a duplicate origin of the left vertebral artery and a hyperechoic thrombus at the origin of 1 of the duplicated arteries. CT angiography of the lower neck area demonstrated duplicated vertebral arteries on the left side. MR angiography of the vertebrobasilar system did not show duplication, indicating that the duplicated vertebral arteries fused at a level higher than C2.
PURPOSE: The purpose of this study was to evaluate the Doppler sonographic blood-flow parameters and spectral patterns in the inferior mesenteric artery (IMA) and superior mesenteric artery (SMA) in patients with active and inactive (remission-phase) ulcerative colitis (UC). METHODS: The IMAs and SMAs of 25 patients with active-phase UC (group 1), 19 patients with remission-phase UC (group 2), and 22 healthy, asymptomatic subjects (control group) were evaluated by duplex Doppler sonography. The 25 patients in group 1 were categorized into 2 subgroups on the basis of the extent of disease as determined by double-contrast barium enema x-ray study and colonoscopy. The first subgroup (group 1a) consisted of 11 patients with active involvement of the left colon from the rectum to the splenic flexure. The second subgroup (group 1b) consisted of 14 patients with active involvement of the entire colon. The peak systolic velocity (PSV), end-diastolic velocity (EDV), mean velocity (Vmean), resistance index (RI), and pulsatility index (PI) were determined from the Doppler spectral analysis. The inner diameter and cross-sectional area of the IMA and SMA were measured, and the blood-flow volume was calculated. The results were compared between the patient groups and control subjects. RESULTS: In the IMA, the mean blood-flow volume, mean PSV, mean EDV, and Vmean were significantly higher, the mean PI was significantly lower, and the mean diameter and the mean cross-sectional area were significantly larger in group 1 than in group 2 or in the control group (p < 0.001). The mean PSV and the Vmean of the IMA were significantly higher in group 1a than in group 1b (p < 0.05). The mean blood-flow parameters in the SMA were not significantly different between groups 1 and 2 or between either group 1 or group 2 and the control subjects. The mean EDV in the SMA was significantly higher and the mean PI and the mean RI were significantly lower in group 1b than in group 1a (p < 0.01). CONCLUSIONS: Duplex Doppler sonography of the IMA and SMA can be used to evaluate inflammatory disease of the large bowel, to assess disease extent, and to document response to therapy.

Lymphangiomyoma is an extremely rare tumor occurring exclusively in women of reproductive age. The tumor is characterized by proliferation of immature smooth muscle along the lymphatic vessels of the abdomen, thorax and lung. Although lymphangiomyoma has been reported in a young girl and a girl infant, none has been reported in boys. We report herein a case of lymphangiomyoma in a two-year-old boy. The unusual presentation in this patient was that the tumor arose from the small bowel mesentery without any evidence of lung involvement. The tumor was extirpated and lymphangiomyomatosis was confirmed pathologically.
