Para-articular chondroma is a benign chondroid tumor which is frequently seen in the infrapatellar fat pad of the knee. We report a para-articular chondroma case located in the popliteal fossa which is very uncommon. Eighty-two-yearold male was presented to the department of orthopedics with a history of chronic pain and swelling at the popliteal fossa of his right knee. The patient was investigated using the following techniques; plain radiograph and MRI which gave an impression of a benign para-articular chondroma arising from the popliteal fossa. Radiographically, a welldelinated mass with spherical calcifications in the popliteal fossa was detected on the X-ray of the knee. On MRI, isointense signal intensity with adjacent muscles on T1-weighted TSE sequence and heterogeneous high signal intensities suggestive of chondroid matrix and oedema on fat-supressed T2-weighted sequence were detected. On postcontrast images peripheral enhancement in the chondroid lobules which was typical for chondroma was seen. After surgical resection, histopathological examination revealed para-articular chondroma.Keywords: Chondroma, soft tissue neoplasms, magnetic resonance imaging, knee. Öz Para
