[Primary psoas abscess in children: 6 cases].
BACKGROUND
Primary psoas abscess is very rare in childhood; its diagnosis and treatment can be improved by the use of recent imaging techniques.


METHODS
Six children, aged 11 months to 10 years (mean: 51 months) were admitted from January 1987 to 15 December 1993 because they suffered mainly from fever, lumbar pain and/or homolateral flexed hip. Examination showed a painful inguinal mass in five patients and hyperleucocytosis in all. X-rays showed disappearance of the external limit of psoas in two patients; ultrasonography showed enlarged psoas in all, associated with hypoechogenic mass in two and without echo in four patients. CT scan showed the abscess in all cases, permitting a needle aspiration for bacteriological studies: Staphycococcus aureus was present in five cases. Drainage of the abscess by CT-guided percutaneous catheter was performed in two patients. Surgical drainage was performed in three including one for whom percutaneous catheter drainage did not succeed. The two other patients were only given antibiotics.


CONCLUSIONS
CT-guided needle aspiration to establish presence and nature of fluid collection is a well established technique that may be extended to treatment of psoas abscesses.
