Anal pain is among the most frequent complaints referred in coloproctology clinic. Nevertheless, this symptom may have a great variety of etiopathogenetic causes. This is the first report that highlights the presence of a rare cause of anal pain, originated by ingested seeds. A 65-year-old male had a 4-day history of fever, anal pain, and discharge. A three-dimensional endoanal ultrasound revealed two perianal abscess cavities with central hyperechogenic areas, in the absence of acoustic shadow. The patient underwent examination under epidural anesthesia, where the two cavities were drained endoanally. Two cereal grains (linseed/sunflower seed) were found during the drainage of the abscess. The utilization of endoanal ultrasound in the investigation of perianal pain is a valuable option. In addition, apart from the size and the exact dimensions of abscesses, endoanal ultrasound also permits the clarification even the most remote etiopathogenetic causes of anal pain.
肛门疼痛是结直肠科门诊最常见的主诉之一。然而，这种症状可能有多种病因。这是第一份强调因摄入种子引发的罕见肛门疼痛病因的报告。一名65岁男性有4天的发热、肛门疼痛和分泌物病史。三维肛管超声显示两个肛周脓肿腔，中央有高回声区，无声影。患者在硬膜外麻醉下接受检查，两个脓肿腔经肛管引流。脓肿引流过程中发现两颗谷物种子（亚麻籽/向日葵籽）。肛管超声用于肛周疼痛的检查是一种有价值的选择。此外，除了脓肿的大小和确切尺寸外，肛管超声还能明确肛门疼痛最隐匿的病因。
