A Case of needle-tract implantation of hepatocellular carcinoma in the ovary after radiofrequency ablation / 고신대학교의과대학학술지

Radiofrequency ablation (RFA), a local ablative modality, is gaining acceptance for the treatment of liver malignancies. Despite a relatively low complication rate, tumor seeding resulting from RFA in hepatocellular carcinoma (HCC) treatment can occur. A 44-year-old woman was diagnosed with HCC. Spiral computed tomography (CT) revealed a 2.3 × 2.0-cm mass in the S5 segment, which was treated with RFA on May, 2005. Follow-up imaging, performed at 6-month intervals after RFA, showed complete tumor necrosis. In October 2009, CT revealed a heterogeneous mass, 5.7 cm in diameter, in the right ovary. Since the lesion was limited to the right ovary without evidence of spread, bilateral salpingo-oophorectomy was performed. Histopathology indicated that the metastatic spread from the HCC to the ovary was positive for hepatocyte-specific antigen on immunohistochemistry. The ovary is a rare site for HCC metastasis. Moreover, needle tract implantation of HCC in the ovary is very rare.

Subtemporal Approach vs. Pterional Approach in Basilar Bifurcation Aneurysms: 2 Case Reports

Two patients with basilar bifurcation aneurysm were treated by different approach, low lying posteriorly projecting aneurysm was clipped with subtemporal approach and high bifurcated basilar bifurcation aneurysm with multiplicity approached through pterional method. The author reviewed literature concerning the approaches of basilar bifurcation aneurysm.

Clinical Analysis of Spinal Cord Tumors:Review of 105 Cases(981-1991)

The authors analyzed 105 cases of spinal cord tumor in regarding to the age, sex, location and distribution, clinical presentation and postoperative outcome. They were confirmed by pathologic study at the Kyung Hee Medical Cented from 1981 to 1991. The incidence of spinal cord tumors was slightly predominant in males. The most commom tumor was neurogenic tumor. The neurogenic tumor composed 43.8%(46 cases), and the rests were meningioma 15.2%(16 case), metstasis 10.5%(11 cases) and others. The tumor were located most frequently in the thoracic area(31.4%) and in the intradural extramedullary space(56.1%). Most common initial symptom of spinal cord tumors were pain and it's mean duration was 8.3 month. The patients were assigned to one of four groups according to their neurologic deficit. About 66.6%(70 cases) of the patients were included in Groups I and II(mild neurologic deficit), and others were classified in Groups III and IV(significant to severe neurologic deficit). Complete tumor removal was achieved in 70.4%(4 cases) of the patients, and subtotal removal was performed in 26.7%(28 cases), and biopsy was performed in 2.9%(3 cases). Among the 105 patients, the postoperative outcomes on dischage were recovery in 36 cases(34.3%), improved in 45 cases(42.9%), stationary state in 12 cases(11.4%), and progression in 12 cases(11.4%).
