Meralgia paresthetica, a pain syndrome that is caused by injury to the lateral femoral cutaneous nerve, is a well-documented complication after anterior hip arthroplasty (THA). Traditional treatment of this peripheral nerve entrapment syndrome can be complicated in patients who have had THA via an anterior approach owing to the presence of scar in the postoperative bed. ⋯ Minimally invasive intra-abdominal treatment of meralgia paresthetica following anterior THA results in durable pain relief. This approach is a helpful alternative to traditional techniques of decompression or section of the lateral femoral cutaneous nerve below the inguinal ligament.

Primitive neuroectodermal tumors (PNETs) are rare malignant neoplasms in the spinal cord that comprise undifferentiated or poorly differentiated neural crest cells. PNETs imaging findings lack specificity, making diagnosis difficult. ⋯ This paper reports a very rare case of PNETs with multiple lesions in the spinal cord that mimicked acute myelitis and emphasizes that multiple PNETs lesions detected by magnetic resonance imaging could have an initial acute myelitis-like presentation, which should be considered a differential diagnosis.
