# Adult Ileocolic Intussusception Following Appendectomy: A Case Report of a Rare Sonographic Finding

## TL;DR

This case report describes a rare instance of adult ileocolic intussusception following an appendectomy, highlighting the diagnostic role of ultrasound.

## Contribution

The report presents a rare sonographic finding of adult intussusception after appendectomy and emphasizes ultrasound's diagnostic utility.

## Key findings

- Ultrasound identified characteristic features like target appearance and pseudokidney sign in adult intussusception.
- Doppler ultrasound showed no internal flow, suggesting possible ischemia.
- The case underscores the importance of ultrasound in initial evaluation and the need for further imaging.

## Abstract

Adult intussusception is a rare condition characterized by the telescoping of one segment of the intestine into an adjacent segment. Prompt recognition and intervention are crucial due to the potential for serious complications. The present case is of adult ileocolic intussusception in a 47-year-old male patient who underwent appendectomy three weeks prior. The patient presented with constipation, lower abdominal pain, and vomiting. A transabdominal ultrasound revealed characteristic sonographic features, including a target appearance at the transverse view and the pseudokidney sign of the longitudinal view associated with the presence of reactive lymph nodes. Doppler ultrasound indicated no internal flow, suggesting possible ischemia. This case highlights the role of ultrasound in the initial evaluation of adult intussusception and emphasizes the need for further imaging modalities for detailed anatomical evaluation and lesion identification.
