The deep postanal space is located posterior to the anal canal. In the sagittal plane, it is delimited on the anterior side by the external sphincter complex, the posterior-inferior side by the coccyx and anococcygeal ligament, and above by the superior levator ani muscle. An abscess located in this space is known as a deep postanal abscess (DPA) and can cause posterior horseshoe abscesses. Clinical suspicion, diagnosis and emergency treatment are a challenge for general surgeons. We present a real case using an illustrative video that shows how to identify a DPA on computed tomography and how to perform correct surgical drainage.
