JUXTA-ADRENAL MALIGNANT SCHWANNOMA

A case of malignant schwannoma occurring in an 11-year-old boy is desc ribed. To our knowledge, this is the third case of malignant juxta-adr enal schwannoma reported in the literature. It was misdiagnosed at the onset of the disease as a post-traumatic renal hematoma. Angiography revealed that the tumor derived its blood supply from collateral vesse ls of the aorta, splenic, and left gastric arteries. An analysis of th e diagnosis, clinical course, and prognostic factors of this rare tumo r is performed.
