[Testicular seminoma and multifocal aseptic osteonecrosis following chemotherapy]

Multifocal osteonecrosis has a wide variety of etiologies, but in the cancer patient several risk factors could have a synergic effect (chemotherapy, radiotherapy, corticosteroid, metabolism disorder).

A patient with testicular seminoma receiving cisplatin-based chemotherapy and short-term corticosteroid developed multifocal osteonecrosis. Early diagnosis of osteonecrosis is important to prevent orthopedic complications.

Cisplatin could represent one of the possible etiologies of multifocal osteonecrosis. Magnetic resonance imaging has a high sensitivity and specificity in the diagnosis of osteonecrosis and should be used when this condition is suspected.
