Figure1. Edema and fluid collection within left iliopsoas muscle and left pectineus with fluid collection within left iliopsoas muscle
No blood or bone marrow culture was performed due to the low chance of detection and the long time required (1). Based on these findings, the diagnosis of Brucellosis was made and according to the Textbook of Pediatrics Nelson (3,4), the patient was treated with Rifampin (600 mg/ daily) and Doxycyclin (200 mg/ q12h). Despite the consult of the orthopedic surgeon regarding surgical drainage, we waited to observe the patient’s response to antibiotic therapy.
After the initiation of the medical treatment, the signs and symptoms of the patient started to resolve.
At discharge, the gait pattern of the patient was normal. He had no complaints of inguinal pain, fever, malaise, or any other symptoms.
In six months of follow-up, no relapse occurred. Ultrasound was performed and showed no evidence of Psoas abscess.
Therefore, the patient was treated successfully only with Oral medication and without any abscess drainage.
