[Copeman nodules, a frequent but little known cause of low back pain; case report]. / Nódulos de Copeman, una causa frecuente pero poco conocida de dolor lumbar: presentación de un caso.

Copeman nodules or episacral lipomas are a very prevalent entity in the general population. They consist of subfascial fat herniations at the episacral region, through weakened areas of the overlying thoracodorsal fascia. They are usually bilateral and symmetric. Only in rare cases they are the cause of clinical manifestations. We present the case of a 63-year-old woman who presents with lumbar pain refractory to conventional treatments. Ultrasound examination suggests the diagnosis of Copeman nodules. The treatment of the patient is approached from a multidisciplinary perspective, finally deciding to operate the patient. After the intervention, the symptoms remitted shortly, allowing the patient to continue a normal life without discomfort or analgesic treatment.
