Multiple Retained Needles in the Neck of a Drug User: A Case Report

Retained needles are frequently observed in intravenous drug users. However, an incidental discovery of multiple needles at the neck seldom occurs. These foreign bodies remain either asymptomatic or cause local and central complications that can be fatal. We report the case of a 43-year-old male having a medical record of human immunodeficiency virus and hepatitis C who presented to our department with a 3-day history of a febrile lateral neck swelling. He reported a history of repetitive intravenous drug use and previous abscesses that were surgically drained. We noted a left and tender 8 cm neck swelling with torticollis. Computed tomography scan showed a collected myositis of the sternocleidomastoid muscle in association to multiple metallic foreign bodies at the neck that were compatible with the aspect of broken needles. Imagery also showed a thrombosis of the ipsilateral jugular vein. No central embolism of a foreign body was noted. We performed a surgical drainage of the muscular abscess and managed to retrieve a 1 cm broken needle that was retained at the level of the collection. We did not retrieve the other needles since they were asymptomatic. The patient was placed under intravenous antibiotics for 1 week followed by oral amoxicillin-clavulanate with a total regression of the cellulitis. At the further follow-ups, the rest of the foreign bodies remained asymptomatic. Our study emphasizes on the importance of suspecting a retained foreign body in intravenous drug users to ensure an adequate management of the possible complications and to protect the medical team from incidental needle injuries.
