case_images: Computed tomography (CT) image of the lower gluteal region of the patient in case 2. White-colored areas correspond to the bones. The white arrow indicates areas of low attenuation (black) corresponding to significant fat within the inferior aspect of the left Gluteus Maximus muscle adjacent to the sciatic nerve (SN)

case_images: Post-operative computed tomography (CT) in our institution revealed distension of the inferior aspect of the left Gluteus Maximus muscle with fat in an area adjacent to the sciatic nerve (Fig. 1).
case_images: F-waves (a, b) and H-reflexes (c, d) of the left and right posterior Tibial nerves. F-waves correspond to the left posterior Tibial nerve (a) and right posterior Tibial nerve (b) and indicate absence of transmission in the distal motor nerve on the left. H-reflexes correspond to the left posterior Tibial nerve (c) and right posterior Tibial nerve (d) and indicate an absent reflex between type IA afferent and efferent nerves of the same muscle on the left. F-waves and H-reflexes corresponding to the right posterior Tibial nerve are normal

case_images: NCV studies of the lower extremities indicated the absence of posterior Tibial F-responses and posterior Tibial H-reflex on the left side compared to normal responses on the right side (Fig. 2).
