Epidural abscess imitating recurrent pilonidal sinus: a case report

Pilonidal sinus or pilonidal cyst is a common benign disease, affecting mostly young working men. We present the first case of an epidural abscess imitating pilonidal sinus. A 33-year old male, suffering from previously undiagnosed and untreated diabetes mellitus (DM), presented to our emergency department (ER), one month after open surgical treatment of pilonidal sinus, due to weakness and fever. After re-operation of the pilonidal cyst and due to post-operative pus production and continuation of fever a computer tomogr aphy (CT )scan was performed revealing an epidural abscess extending from the thoracic vertebrae 12 (T-12) to the sacrococcygeal area. At that point he underwent new surgery for drainage of the epidural abscess. The patient received intravenous antimicrobial treatment and was discharged on the 23rd postoperative day without signs or symptoms of infection. At follow up for a whole year no signs of recurrence have been observed.
