Pyomyositis is an uncommon clinical entity affecting predominantly pediatric population. It presents with diffuse muscle involvement, mostly in the lower limb, with occasional abscess formation and need of drainage, coupled to an appropriate antibiotic therapy.
In this article we present a case of a previously healthy 11-year old boy with an acute onset of hip pain and fever, as well as elevation in blood leukocyte count and C-reactive protein. Magnetic resonance imaging showed a gadolinium-enhanced oedema of internal obturator, external obturator, adductors and quadratus femoris, with an intra-muscular abscess of external obturator. After two attempted percutaneous drainages the patient progressed to sepsis, with the need of open surgical drainage through transgluteal approach. Concomitantly, a deep venous thrombosis was also diagnosed.
After the appropriate drainage and a prolonged antibiotic regimen, patient’s condition improved, with full recovery and no sequelae.
