Tumoral calcinosis is a rare cause of intratissular calcifications in hemodialysis patients with chronic renal failure. Its frequency is estimated between 0.5 and 7% of patients. We illustrate through a case of unusual localization diagnosed in our institution, the radiographic and scannographic aspect of this little known entity. A 40-year-old man, followed for hypertensive cardiopathy, in chronic renal failure for 12 years under hemodialysis, consulted for bilateral inguinal swellings evolving in a progressive and painless way. Biological investigations revealed hyperparathyroidism with increased phosphocalcic product. He was referred to us for radiological evaluation which revealed lesions in favor of bilateral pubo-inguinal tumor calcinosis. Tumoral calcinosis is a rare cause of intratissular calcifications in chronic renal failure patients undergoing hemodialysis. Pubic localization with infiltration and osteolysis of the symphysis pubis is very rare. Its main risk factors are the existence of hyperparathyroidism, an increase in phosphocalcic product and probably local traumatic factors. Tumoral calcinosis has a typical appearance on radiographs: amorphous, cystic and multilobulated calcifications of periarticular distribution. The CT scan allows a better delineation of the calcified mass. Its treatment remains controversial. The knowledge of osteoarticular manifestations of chronic hemodialysis patients, especially tumoral calcinosis by radiologists, allows to easily make the diagnosis and thus avoid invasive complementary explorations for the patient and to quickly institute an effective treatment.
