Computed tomography of a traumatic, diaphragmatic, Richter's hernia: findings mimicking an abscess

We present a case of a Richter's hernia through a traumatic, diaphragmatic defect presenting with the appearance of an abscess on computed tomography. We underscore the importance of this hernia variant, the need for its recognition, and stress caution in percutaneous aspiration of a lesion where a hernia might exist.
