Abstract
Primary retroperitoneal tumors are rare, and benign retroperitoneal tumors are exceptionally rare. Herein, we present a very rare case of benign concomitant retroperitoneal intramuscular hemangioma and intravascular papillary endothelial hyperplasia, with the unusual presentation of lumbosacral plexopathy. After surgical treatment and rehabilitation, the patient recovered uneventfully. This case report should serve to remind physicians of the rare condition of a retroperitoneal tumor leading to a neurological deficit.
Highlights
Intravascular papillary endothelial hyperplasia (IPEH) is an exceptionally rare disease, with only one case arising from the retroperitoneum published in the literature [3]
Present an unusual case with concurrent intramuscular hemangioma and intravascular papillary endothelial hyperplasia (IPEH) in the retroperitoneum complicated with right side lumbosacral plexopathy
No previous published case of a patient presenting with acute sciatica complicated with lumbosacral plexopathy was found in our literature review
Summary
Primary retroperitoneal tumors are rare, accounting for only 0.07% to 0.6% of all tumors at the same location, and 62% to 82% of these tumors have been reported to be malignant [1]. Benign retroperitoneal tumors are rare, and vascular malformations such as hemangioma are exceptionally rare comprising only 0.5% to 2% of all retroperitoneal tumors [2]. Intravascular papillary endothelial hyperplasia (IPEH) is an exceptionally rare disease, with only one case arising from the retroperitoneum published in the literature [3].
