A 42-year-old female presents with difficulty moving her right leg and paresthesia of portions of her left buttocks and leg. Detailed muscle testing of the right leg reveals weak hip extension and abduction. Knee extension is normal but flexion is weak. All ankle and foot movements are weak. Muscle testing of the left leg reveals no deficits. Sensory testing reveals no deficits on the right leg. The patient is unable to feel temperature or pinprick on the posteromedial left buttocks, thigh, and calf. A lesion of what spinal tract would explain the sensory deficits that she is experiencing?
