Abstract

AIM:

To report on the clinical features, diagnosis, and treatment of psoas abscess (PA) with special attention to the presence of septic shock.

PATIENTS AND METHODS:

This study included 17 patients (mean age 66.2, range 43-81 years) with PA. Treatment consisted of intravenous administration of antibiotics and abscess drainage, either surgical or percutaneous with ultrasound guidance.

RESULTS:

The typical patients presented with fever >38 degrees C (16/17, 94%), pain in back, flank, or abdomen (15/17, 88%), hip flexion contracture with pain extension (14/17, 82%), and mass felt in the flank (5/17, 29%). All 8 patients without septic shock (100%) had the clinical triad (fever, pain in back, flank, or abdomen, and hip flexion contracture) as compared with 4 of 9 patients with septic shock (44%) (p = 0.012). The duration of symptoms before hospitalization was significantly shorter in the patients with septic shock (median 2, range 1-5 days) than in those without septic shock (median 18.5, range 11-63 days; (p = 0.0005). The mortality rates were 33% (3 of 9) and 0% (0 of 8) in the patients with and without septic shock, respectively (p = 0.071).

CONCLUSIONS:

PA patients with septic shock had a tendency to have nonspecific symptoms and an occult clinical course as compared with those without septic shock. A delay in diagnosis and treatment can result in a worse clinical outcome (death or totally disabled state). Increased awareness of this condition should lead to earlier diagnosis and treatment with improved outcomes.
