摘      要：BACKGROUND Schwannomas are rare,often benign,tumors deriving from Schwann cells that have low incidence in the retroperitoneal region(0.5%to 5%).Their diagnosis is hardly confirmed at early stage due to lack of specific features in signs,symptoms and imaging ***,it is necessary performing guided punch biopsy in order to identify *** removal is the treatment of choice due to its low sensitivity to radiation and *** SUMMARY Forty-seven years old female patient who was hospitalized for elective orthopedic procedure,without complications,evolved with severe pain in the lower limbs,thigh and gluteal region associated with neurogenic *** pain required magnetic resonance imaging(MRI)of the lumbar spine,which showed epidural collection with dural compression and massive heterogeneous perihepatic nodular *** surgical team opted for draining the collection,as well as requested an MRI of the abdomen and pelvis,whose analysis showed expansive lesion in the retroperitoneum,in close contact with the inferior vena cava and with the right renal vein.A guided puncture was performed for diagnostic clarification,which showed immunohistochemical profile compatible with *** selected treatment comprised retroperitoneum tumor resection in association with laparoscopic *** patient was discharged and remained stable after 4-mo follow-up;she remains under followup to check the need of cancer *** Schwannoma features requires surgical treatment based on laparoscopic resection,which often presents low relapse rates and optimistic prognosis.
