Rectal abscess secondary to foreign body insertion: A case report.

BACKGROUND

Rectal foreign bodies, though uncommon, present diagnostic and therapeutic challenges, particularly when they result from accidental ingestion. The nonspecific symptoms and the potential for serious complications necessitate a thorough and methodical approach to diagnosis and treatment. This case report aims to highlight the diagnostic complexities and management strategies involved in treating a patient with a rectal foreign body, focusing on the use of advanced imaging techniques and the importance of a multidisciplinary approach.

CASE SUMMARY

A 48-year-old male with a history of hypertension presented with a one-year history of post-defecation anorectal pain and mild post-defecation rectorrhagia. Initial evaluation revealed hemodynamic stability and a tender, non-mucosal lesion in the anterior left rectal region. Imaging studies, including colonoscopy, magnetic resonance imaging, and endosonography, identified an erythematous, exophytic lesion and a perirectal abscess containing a foreign body. Surgical intervention revealed necrotic tissue and purulent material, along with two solid foreign body fragments (bone or plant matter). Postoperative follow-up showed the patient in good condition, and pathology confirmed the fragments as mature bone.

CONCLUSION

This case underscores the diagnostic challenges posed by rectal foreign bodies with nonspecific symptoms and no clear history of ingestion.
