Abstract
An 18-year-old male patient presented with chronic nonspecific pain of three months located at his left proximal tibia. The patient was admitted to our department for plain X-ray, computed tomography and magnetic resonance imaging examination. Plain X-ray and computed tomography revealed a geographic lytic lesion at the medial aspect of the proximal tibia. Biopsy of the lesion showed telangiectatic osteosarcoma. Image findings of all modalities are presented.
Highlights
Telangiectatic osteosarcoma is an uncommon histopathologic subtype that represents 2.5 -12% of all osteosarcomas [1]

Summary
Telangiectatic osteosarcoma is an uncommon histopathologic subtype that represents 2.5 -12% of all osteosarcomas [1]. [2] Radiologic findings of such a case in plain X-ray, CT and MRI are presented. Case presentation An 18-year-old male patient from Greece was admitted to our department due to chronic nonspecific knee pain (for the last 3 months) for a plain X-ray and an MRI examination. Plain X-ray (Figure 1a,b) revealed a geographic lytic lesion at the medial aspect of the proximal tibia with no evidence of soft tissue mass or internal calcifications. CT examination (Figure 2) confirmed the findings of plain X-ray and showed a lytic geographic lesion with wide zone of transition at its lateral aspect causing slight expansion and thinning of the cortical bone, scalloping of the endosteum, no soft tissue extraosseous mass. As far as the authors known, the patient had not been investigated for possible germline mutations of the tumour suppressor gene TP53
