Persistent back pain due to an iliopsoas abscess

We present a 14 years old patient with unremarkable medical history, that begins spontaneously with low back pain that does not improve with standard treatment (rest, heat and non-steroidal anti-inflammatory drugs), with progressive worsening of pain, for which he consults four times in different medical centres. The final diagnosis is an iliopsoas abscess, seen on a lumbar Computerized Tomography, and he is consequently admitted to hospital to receive intravenous antibiotics.

The patient in our case has a good response to treatment, without any complications or serious squeals, and without requiring a surgical drainage of the collection.
