Retroperitoneal ganglioneuroma (RGN) is a rare benign tumor that arises from the retroperitoneal sympathetic ganglia composed of mature Schwann cells, ganglion cells and nerve fibers. These tumors can occur anywhere along the paravertebral sympathetic plexus and occasionally from adrenal medulla. Although they grow in excessive size, they may cause compression to adjacent organ or structures thus giving rise to symptoms. Resecting RGN’s is a challenging endeavor, as they tend to encase neighboring vessels to their site of origin. The reported case is a 43-year-old male who presented with lumbar pain that increased progressively in intensity over the last 6 months. Preoperative investigations revealed a large tumor with encasement of the origins of the superior mesenteric artery and bilateral renal arteries. The tumor was completely resected and the final pathology confirmed the diagnosis of RGN.

Background Supralevator abscess is a rare form of anorectal disease responsible for very rare but morbid manifestations, one of which is superior spread through fascial planes. Case presentation We present a rare case of a spreading anorectal abscess in a patient who presented with only diffuse abdominal pain, and we review similar cases in the literature according to anatomical considerations, presentation, diagnostic procedures, and treatment options. Discussion We identified seven previously reported cases of spreading anorectal abscesses. Most abscesses had a horseshoe morphology, and all patients presented or developed abdominal pain. All patients had perianal swelling and pain. Five out of seven patients were previously mistreated. Only two abscesses spread through both the pre-and retroperitoneal planes. Conclusion Abdominal pain is a dominant feature of extraperitoneal inflammation originating from anorectal abscesses. The absence of perianal signs is rare, and proper inspection of the patient along with the medical history can lead to quicker diagnosis and decisive treatment.
