Abstract

After slip down, a 64 years old female had pain on the left buttock and the back without weakness or sensory change. Physical examination revealed tender points on left buttock and quadratus lumborum muscle. Straight leg raising test was 40^o/20^o. After trigger point injection on tender points, her symptoms were improved. Magnetic resonance imaging showed central extruded disc at L3-S1. After systemic steroid therapy was started, fever was developed about 39.3^oC and laboratory evaluation showed inflammatory sign. Systemic steroid injection was stopped. Physical examination revealed a palpable and painful mass on the left lower quadrant of the abdomen. Ultrasonography and computerized tomography of abdomen and pelvis showed a large (7⁓5 cm) irregular shaped cystic mass along left iliopsoas muscle. Percutaneous catheter was inserted for drainage. Thick turbid yellow-greenish pus (300 cc) was drained. Intravenous antibiotics were administered and the patient's symptoms gradually improved. Culture of the pus revealed Streptococcus agalactiae.
