ABSTRACT

Schwannomas are tumors of neural origin and account for 1% of retroperitoneal tumors. In many times, they are benign tumors and just 5 to 8 % are malignant; high degree is even less frequent in its histology. This is a male patient aged 46 years with no history of chronic degenerative problems and diagnosis of type I neurofibromatosis. The disease appeared three years before his admission to hospital in 2013 because of right knee arthralgia associated to myalgias on the same side. Diagnostic support was requested in terms of performance of magnetic resonance of dorsal and lumbar spine; this test reported the presence of a tumor in the right side of the retroperitoneal region, it measured 10 × 17 cm with apparent spinal origin in L2 and L3. Although they are often masses of benign neural origin, their malignization is not rare. There was a cavity with adjoining structures affected by the tumor. In this type of cases, the preoperative management with multidisciplinary involvement both in the preoperative preparation and during the surgical procedure is of vital importance.
