Article abstract


We present a case of a 37-year-old male security officer with fever, severe low back pain radiating to left lower leg and diminished mobility for 1 week. His Lumbar spine X-ray was unremarkable, but his inflammatory markers including CRP, ESR and Neutrophils were high. CT scan with contrast showed rim enhancing fluid collection within the left obturator foramen with inflammatory change in the mesorectal fat. Confirmatory MRI scans depicted inflammatory change in the left piriformis muscle and a localized collection without any abnormality in the spine. Urgent CT guided aspiration was performed and the sample sent for microbiological analysis. Intravenous antibiotics commenced and continued for two weeks with complete resolution.
