[Crohn's disease with anoperineal lesions: use of MRI]

Area of Science:

• Gastroenterology
• Radiology
• Colorectal Surgery

Background:

• Crohn disease is a chronic inflammatory condition that can affect any part of the gastrointestinal tract.
• Anoperineal manifestations, including anal fissures and abscesses, are common in Crohn disease but can be challenging to diagnose and manage.
• Perineal involvement in Crohn disease requires accurate diagnostic imaging for effective treatment planning.

Observation:

• A patient with Crohn disease presented with multiple anal fissures and persistent fever, but no obvious signs of abscess on physical examination.
• Magnetic Resonance Imaging (MRI) of the pelvis revealed a recto-vaginal wall abscess, which was not clinically apparent.
• The patient underwent surgical intervention under general anesthesia for the identified abscess.

Findings:

• Pelvic MRI is highly effective in the precise diagnosis of complex anoperineal lesions associated with Crohn disease.
• Early and accurate diagnosis of intra-pelvic abscesses is critical for timely surgical management.
• This case underscores the diagnostic utility of advanced imaging in complicated Crohn disease presentations.

Implications:

• Radiologic imaging, especially pelvic MRI, should be considered in patients with suspected or confirmed Crohn disease and persistent symptoms suggestive of deeper infection.
• Improved diagnostic accuracy can lead to more targeted and effective treatment strategies for anoperineal Crohn disease.
• This case contributes to the understanding of the diagnostic challenges and imaging-based management of Crohn disease complications.
