We report a case of meralgia paresthetica occurring in an amateur baseball pitcher who experienced inguinal pain and dysesthesia
in the anterolateral thigh during pitching practice. The lateral femoral cutaneous nerve was pushed up by the iliac muscle
to the inguinal ligament at the sharp ridge of its fascia and ensheathed in the tendinous origin of the sartorius muscle.
Neurolysis of the lateral femoral cutaneous nerve and partial dissection of the inguinal ligament and sartorius muscle promptly
relieved the symptoms and the patient resumed pitching 1 month later. These anatomic variations of the lateral femoral cutaneous
nerve in the inguinal region might render the nerve susceptible to compression and irritation, and repetitive contraction
of inguinal muscles during throwing motion might induce and exacerbate the neuropathy of the lateral femoral cutaneous nerve.
