case_images: Magnetic Resonance Imaging (MRI) revealed a well-defined heterogeneous mass (7 x 4, 4 x 3, 3 cm), posterior to the sciatic nerve, just above the popliteal fossa (Figure 2).
case_images: A sagittal T2-weighted MRI shows hyperintense signal in the mass with a heterogeneous aspect.

case_images: A T2-weighted MRI showed hyper intense signal in the mass (Figure 3).
case_images: (a) Schwannoma in situ. (b) It was located just above the polpiteal fossa, originating from the sciatic nerve proximal to its bifurcation.

case_images: A well-delineated tumor was identified, originating from the sciatic nerve proximal to its bifurcation (Figure 4).
case_images: (a) Macroscopic aspect of the tumor. The size was +-6 x 4 cm. (b) Note the heterogeneous aspect inside the tumor.

case_images: The tumor was completely excised with preservation of the functioning fascicles (Figure 5).
case_images: This figure clearly shows the palisading elements of the Antoni A cells (1), low cellular regions, called Antoni B areas (2) and a blood vessel with a hyalinized wall (3).
