Retroperitoneoscopic drainage of a psoas abscess

Case report
A 4-years-old boy presented with a 5-day history of fever, limp, and pain in the left loin. He was febrile with tenderness in the left loin and flexor spasm of the left hip joint. The white cell count was 22,000/mm3 with 80% neutrophils. Ultrasonography of the abdomen showed an abscess cavity measuring 5 cm × 5 cm in the region of the left psoas muscle, with a completely inflamed psoas muscle. The patient underwent magnetic resonance imaging (MRI), which confirmed presence of large psoas
Discussion
Psoas muscle abscess is rare and presents a diagnostic challenge with a high index of suspicion.3 It can be primary, from hematologic spread of organisms, or secondary to an infective process in the vicinity. Pyogenic iliopsoas abscess in the pediatric age group is a primary condition caused mostly by S aureus. Other offenders are Escherichia coli and other Enterobacteriaceae.4 Of late, psoas abscesses are only rarely caused by Mycobacterium tuberculosis,4 more so in the developing countries.

Primary iliopsoas abscess has a good prognosis, with a mortality rate of 2.4%, compared with 18.9% in secondary cases [8]. Staphylococcus aureus is the most common organism in both primary and secondary iliopsoas abscess, while Escherichia coli is frequently found in secondary psoas abscess with a gastrointestinal or urinary tract origin [9].
