Abstract

We report a 15-month-old girl with right knee pain for 15 days. Physical examination revealed limited range of motion in the right knee. A three-phase bone scan showed asymmetrically decreased tracer uptake in the right knee. Bone scan findings raise suspicion of altered joint biomechanics and reduced physiologic use secondary to pain or a pathology surrounding the right knee that may cause attenuation effect. Subsequent MRI revealed a complicated Baker's cyst in the right knee. This case underscores the significance of indirect findings on bone scans, such as decreased uptake, which in this case was theoretically attribute to reduced regional bloo-flow due to compromised microvascular perfusion OR altered joint biomechanics and reduced physiologic use secondary to pain. It also emphasizes the need to consider atypical causes of knee pain in infants.
