Case of a Vanishing Colonic Mass

Area of Science:

• Gastroenterology
• Colorectal Surgery

Background:

• Colonic ischemia typically manifests as abdominal pain and rectal bleeding.
• A colonic mass is an unusual presentation for ischemic colitis.

Purpose of the Study:

• To report an exceptionally rare case of colonic ischemia presenting as a transient colonic mass.
• To discuss the diagnostic challenges and implications of this unique presentation.

Main Methods:

• A case study approach was employed.
• Clinical presentation, endoscopic findings, and pathological assessments were reviewed.
• Follow-up colonoscopy was performed to assess resolution.

Main Results:

• The patient presented with symptoms initially concerning for a colonic neoplasm.
• Endoscopic examination revealed a prominent mass, leading to suspicion of malignancy.
• A repeat colonoscopy demonstrated complete resolution of the mass, attributed to inflammatory tissue and clots secondary to ischemia.

Conclusions:

• Colonic ischemia can present as a transient mass, mimicking a colonic neoplasm.
• This case underscores the need for a broad differential diagnosis in patients with colonic masses.
• Prompt recognition and appropriate management are crucial for favorable outcomes in colonic ischemia.
