Primary Renal Osteosarcoma Presenting as Hydronephrotic Kidney: A Case Report with Imaging Findings and a Literature Review

다국어 초록 (Multilingual Abstract)

Primary renal osteosarcoma is an extraordinarily rare primary tumor of the kidney. It occurs mostly in middle-aged and older individuals, and generally presents with non-specific symptoms such as abdominal pain, weight loss, palpable mass, and gross hematuria. Radiographically bizarre renal calcifications are often indicative of this uncommon neoplasm. Herein we report a case of primary osteosarcoma in a hydronephrotic kidney of a 76-year-old man, who developed lung metastasis soon after a radical nephrectomy. To the best of our knowledge, this is the first computed tomography based report of a patient with the hydronephrotic form of primary renal osteosarcoma.
