Dear Editor,

We present a peculiar ultrasound finding of proctosigmoiditis in a case of inflammatory bowel disease – ulcerative colitis.

A 35-year-old Male patient came to the hospital with diarrhea and blood in stool for the past 20 days. He had decreased appetite, pain in the abdomen, and weight loss. On investigation, he had moderate anemia with hemoglobin, raised erythrocyte sedimentation rate, and raised C-reactive protein of 7.2 mg/dL, 78, and 8.4, respectively. A sigmoidoscopic examination revealed that the mucosa up to 25 cm from the rectum showed complete loss of vascular pattern, marked erythema, and ulcerations with areas of spontaneous bleeding suggestive of ulcerative colitis. The patient was sent for ultrasound abdomen and pelvis which revealed thickened bowel in the rectosigmoid region with high vascularity on Doppler and maintenance of its stratification and fluid around it. A diagnosis of proctosigmoiditis secondary to ulcerative colitis was made.

Ulcerative colitis is an inflammatory bowel disease characterized by mucosal inflammation of the colon, which is diffuse and affects the rectum extending proximally along variable lengths. The etiology of this inflammation is that although unclear, it seems to have its occurrence in genetically susceptible population in response to environmental triggers. Ulcerative colitis is thought to be an autoimmune disease due to the inflammatory response to colonic bacteria.[1] Ulcerative colitis, excluding the severe types, affects merely the mucosa and submucosa of the colon as an inflammatory ulcer. The mucosa in this scenario is edematous, causing its circulation to increase these correlates with increased bowel wall thickness. The engorged and dilated capillaries of the affected areas probably explain the increased circulation. A transabdominal ultrasound is helpful in the detection of bowel wall thickening and to examine the extent of involved segments of inflammatory bowel diseases.[2]

It is important to note that the typical sonographic appearance of normal bowel wall consists of five concentric, alternately echogenic, and hypoechoic layers from the lumen outward. Bowel wall thickening is a noteworthy sonographic correlate of bowel disorders, which may seem at first glance a very nonspecific sign, but the most widely used diagnostic criterion for the diagnosis of inflammatory bowel disease is thickened bowel wall with increased vascularity with maintenance of wall stratification. The bowel is said to be thickened when the wall is more than 3 mm in diameter.[3],[4]

To conclude, ultrasound has high sensitivity and specificity in the diagnosis of inflammatory bowel disease [Figure 1] and [Figure 2].{Figure 1}{Figure 2}
