Extra-capsular synovial chondroma is a rare condition in which metaplastic cartilaginous mass is formed by the cartilage nodule within the synovial connective tissue break through the joint capsule and continue to proliferate. The authors have experienced a case of giant extracapsular synovial chondroma, affecting the knee joint of 54 years old woman. A case of giant extra-capsular synovial chondroma is reported with brief review of literature.

Undifferentiated embryonal sarcoma(UES) is an uncommon malignant hepatic tumor that occurs in older children and young adults. Six cases of UES were reviewed to determine their characterisfic findings on sonography (US) (n=5), computed tomography (CT) (n=6), and angiography (n=2) US demonstrated a single large, echogenic mass with some anechoic spaces in each case. CT revealed a well demarcated hypodense mass with hyperdense septa of variable shape and thickness. Four cases showed enhancing peripheral rim and some solid portions at the periphery or adjacent to the septa. Follow-up CT scan in one case who had not been treated showed enhancing solid portion changed to hypodense areas. Angiography showed hypovascular or avascular mass. Familiarity with these radiological findings of UES of liver will be helpful in differential diagnosis of primary hepatic tumors of childhood.

Magnetic resonance (MR) imaging of thirteen patients with tuberous sclerosis were reviewed. Seven patients underwent computed tomography (CT). The characteristic MR finding of tuberous sclerosis was those of subependymal nodules which were best seen on short repetition time (TR) spin-echo images. Hypointensities within the nodules consistent with calcification were most evident on long TR images. Contrast enhancing lesions, indicative subependymal giant cell astrocytoma, occurred in four cases. Cortical tubers (n=11) and white matter lesions(n=8) exhibited long T1 and T2 relaxation characteristics although reversed pattern was noted in one newborn patients. Cortical tubers and white matter lesions had more irregular shapes in early childhood patients. MR imaging is the sensitive method in detection of gyral tubers and white matter lesions and also valuable in detecting giant all astrocytoma.

PURPOSE: The Purposes of this article are to illustrate the typical imaging features of eight patients with this syndrome and to discuss the advantage of each imaging modality with a concise review of literatures. MATERIALS AND METHODS: We retrospectively reviewed plain skull radiographs (6), computd tomographic(CT) scans(8), magnetic resonnance(MR) images(4) and cerebral angiograms(3) of eight patients with Sturge-Weber syndrome. We analyzed the radiographic findings of Stu rge-Weber syndrome and compared the findings of CT, MR and angiography. RESULTS: Plain radiographs showed characteristic gyriform calcifications(3) after 2 years of age. CT scans excellently demonstrated cortical calcifications(5), prominently enhancing choroid plexi(5) and dilated periventricular veins(2). MR revealed dilated deep cerebral veins as tubular or spot-like signal void structures at periventricular areas(3) and showed stripes of cortical enhancement after gadolinium infection(2). Angiograph showed dilated tortuous medullary and deep cerebral veins(3) as the collateral pathways of blood shunting. MR was superior to CT in the detection of parenchymal atrophy, venous abnormalities and the extent of angiomatous involvement. Angiography showed enlarged deep cerebral or medullary veins better than MR imaging. CONCLUSION: We think that each imaging modalit including CT, MR or angiography has unique advantages in the diagnosis of this syndrome but MR will be used frequently because of its superior ability for the detection of atrophy, vascular abnormalities and direct visualization of leptomeningeal angiomatosis with contrast enhancement.
