Abstract

Introduction: An anorectal abscess results from the involvement of the anal glands. Its main cause is obstruction of these glands, followed by Crohn’s disease, trauma, malignancy, and immunodeficiencies. Ingestion of a foreign body is a rare etiology, with toothpick trauma described in the literature.

Case Presentation: A 36-year-old man with no relevant medical history presented with a one-week history of sharp abdominal pain, followed by perianal pain accompanied by fever and purulent drainage. Initial evaluation documented an anorectal abscess extending above the levator ani muscle. A subsequent MRI revealed a toothpick as the causative foreign body. The patient underwent surgical management and a 10-day course of targeted antibiotic therapy.

Conclusions: Anorectal abscess due to foreign body ingestion is rare, often unrecognized, and imaging sensitivity is variable. Computed tomography is recommended as the initial imaging modality. Supra-levator involvement requires early and adequate drainage to prevent fistula formation.
