Axial, coronal and sagittal images were obtained, and CT revealed a large 9.7 x 3.8 x 3.6 cm fluid collection in the deep anteromedial mid thigh within the quadriceps muscle with peripheral enhancement, likely representing abscess (Fig. 1).

Comparison with prior lower extremity CT angiogram showed evidence of large residual abscess associated with the right quadriceps with minimal interval change (Fig. 2).

A linear, dense loose body measuring approximately 1 cm in length was seen within the fluid collection (Fig. 3).

A Cook 18 gauge Turner needle was used to enter the abscess cavity and confirmed the loose body to lie dependent within the inferior medial aspect of the abscess as the loose body was readily movable (Fig. 4A). The loose body was then grasped with the clamp and removed along the previously created tract (Fig. 4B).

Post procedure scans were obtained and showed no residual loose body (Fig. 5). CT imaging revealed the abscess cavity to be markedly decreased in size compared to the prior study, measuring 1.4 x 1.0 x 1.0 cm (Fig. 5).
