Abstract: A 16-year-old female athlete presented with increased pain in the distal left lower extremity. A possible stress fracture or shin splint of the left tibia was first considered. A 3-phase bone scintigraphy showed a very small focus of increased activity in the posterior left foot. A diagnosis of os trigonum syndrome was made after SPECT/CT images pinpointed the activity at the left os trigonum.
