Agressive osteoblastoma is a very rare primary bone tumor having locally aggressive and destructive natures.But distant metastasis is not well occurred. Aggressive osteoblastoma may be similar to osteoblastomaradiologically, but has different pathological featurs. We experienced one case of aggressive osteoblastomaarising from left ilium and report this case with review of the literatures.

Neurilemmomas are benign tumors of the nerve sheaths. They are usually painless and are most common in the upper extremities. Pathologically, neurilemmoma is encapsulated and made up of organized element: the Antoni A cells, the Antoni B cells and the Verocay bodies. According to Stout, neurilemmomas never become malignant. Two cases of neurilemmoma of tibial nerve and One case of neurilemmoma of lateral antebrachial cutaneous nerve are presented with a review of the literature. Tumors were enucleated and confirmed by pathological examination.

Tuberculosis and lymphoma, these 2 diseases can present with lyphadenopathy in anywhere of the body. Therefor differentiation of tuberculosis from lymphoma is often difficult. CT scans of 17 patients with tuberculosis and 23 patients with lymphoma were retrospectively reviewed to evaluate the efficacy of CT scans in differentating adenopathy between tuberculosis and lymphoma, All the patients underwent abdominal CT scans with contrast enhancement before treatment. The size, internal architecture, distribution of lymph nodes, and associated findings on CT scans were analyzed. As compared with lymphoma, tuberculous lymphadenopathy showed 1) female preponderance (65%), 2) predilection for portocaval lymph nodes (47%), 3) internal low attenuation in lymph nodes (82%), 4) cold abscess formation (24%). Characteristics of lymphoma on CT scans included 1) male prepondrance (78%), 2) conglomeration of lymph nodes (39%), 3) homogenous internal lymph node structure (83%). These results suggest that evaluation of the characteristics of lymphadenopathy on CT scans is helpful for differentiating between tuberculosis and lymphoma.

Diffuse tremendous thickening of gastric wall caused by excessive proliferation of the mucosa of unknown causewas first decribed by Menetrier in 1888. The disease is highly uncommon, but the exact preoperative diagnosis iscrucial because of the more excellent prognosis than other malignant lesions including gastric lymphoma andinfiltrative gastric carcinoma. The authors recently experienced a case of Menetrier's disease which had beendiagnosed as gastric lymphoma preoperatively. Radiologic differentiation is not impossible between this extermelyrare disease and other mimicking malignant lesions, that is the reason why we introduce radiographic findings ofthe case by comparison with gastric lymphoma of giant rugal type and infiltrative gastric carcinoma. Typical upperG-I series findings of the case are: 1) Enlarged tortuous proximal gastric rugal folds only along the greatercurvature, 2) Perpendicular lines of barium spicules trapped by apposed folds with clubbed or forked appearance,3) Abrupt transition of transion to normal stomach, 4) No luminal narrowing and retained but sluggish peristalsis.Thus radiologists can diagnose Menetrier's disease scrupulously based on critical application of enlarged foldspattern and extent of the lesion in association with other radiologic features and clinial history of fairly longduration. Brief review of clinical and pathologic features about Menetrier's disease is included.

PURPOSE: The aim of this study was to establish a measurement standard for the weight-bearing axial alignment of the lower extremities when performing a lower extremity reconstruction. MATERIALS AND METHODS: Among 274 patients (147 males and 127 females) in their 20s to 30s without any physical disabilities, and who had undergone weight-bearing full leg standing radiographs, 188 patients (100 males and 88 females) were examined this study. The data was analyzed further according to their age and gender using the radiographic value on the coronal and sagittal alignment of the lower extremities. RESULTS: The weight bearing ratio was 38.47+/-10.52% on the coronal plane and 36.11+/-7.88% on the sagittal plane. Both the mechanical axis and the the weight bearing axis were not identical due to their 0.68+/-0.89degrees difference on average. The most adjacent point of the femoral condyles to the tibial plateau on the sagittal plane was assigned to the center of the knee joint. The difference between the mechanical axis and weight bearing axis was 0.04degrees, which was not significant. CONCLUSION: There is a difference between the mechanical axis, which consists of both a line from the center of the femoral head to the center of knee joint and a line from the center of the knee joint to the center of ankle joint, and the weight bearing axis, which is linked directly from the center of the femoral head to the center of the ankle joint. Furthermore, the weight bearing axis passes through the anteromedial part in the knee joint. The center of the knee joint is defined as the most adjacent point of both femoral condyle to the tibial plateau on the sagittal plane.
