- Abstract: Sciatic nerve (SN) is the thickest and longest nerve of the body. Deviations from the normal anatomical origin and level of bifurcation of SN have been frequently reported. In the present case, we are presenting a unique scenario of origin of terminal branches of the SN-tibial nerve (TN) and common peroneal nerve (CPN) in the pelvic region itself from divisions arising directly from the lumbosacral plexus. This variation was associated with origin of posterior femoral cutaneous nerve from the superior division of CPN with anomalous communicating branches between pudendal nerve and TN. The unique characteristics of the present case are the presence of ‘pseudoganglion’ found on the inferior division of TN. The present case stands out as the first of its kind to mention such pseudoganglion. Knowledge of some unusual findings like presence of pseudoganglion and intercommunications between nerves have clinical implications in anesthesiology, neurology, sports medicine, and surgery.
