RESUMO
This is a case of a 26-year-old active duty male with a 1-year history of distal anterolateral leg pain and numbness which would persist following activity cessation. He was referred to physical therapy and eventually orthopedic surgery for bilateral anterior exertional compartment syndrome and underwent bilateral anterolateral fasciotomies. One year after surgery, he continued to have pain along the posterior aspect of his lower legs with residual numbness over his left dorsomedial foot. He was referred to sports medicine for further evaluation and Botox injections without significant symptomatic changes. He subsequently underwent diagnostic ultrasound of his lower legs which showed multiple entrapment points of the left superficial peroneal nerve along the fasciotomy scar. An additional electrodiagnostic study showed left superficial peroneal sensory mononeuropathy. Eighteen months following surgery, he received his first perineural injection therapy (PIT) treatment. A mixture of lidocaine and D5W was prepared to achieve 1 mg/cc which was then injected along his tibial, saphenous, and sural nerves. Following four PIT sessions, the patient's overall lower extremity pain, weakness, and functionality had improved. This case demonstrates potential benefit with PIT in patients with refractory symptoms following surgery for chronic exertional compartment syndrome. These symptoms may be due to chronic irritation of cutaneous nerves and they may benefit from treatment with PIT. Our case may represent a possible paradigm shift in the conservative treatment of chronic exertional compartment syndrome, especially when refractory to surgical compartment release.

Context: A patient followed in the outpatient spinal cord injury support clinic at a VA Medical Center with a prior remote history of a gunshot wound to the back and multiple prior myelograms presented with a recurrent waxing and waning weakness of the left lower extremity and intermittent incontinence of bowel and bladder.Findings: During the evaluation, the patient experienced an immediate albeit temporary improvement in symptoms after a diagnostic lumbar puncture performed for CT myelogram. The symptoms of myelopathy reoccurred several weeks, but then the patient had a similar experience with rapid improvement in symptoms after an accidental fall down a flight of steps. Subsequently, the foot weakness and incontinence returned one week later. The patient ultimately developed permanent improvement in signs and symptoms after surgical intervention which included intradural lysis of adhesions, incision of the arachnoid membrane and resection of a cystic lesion.Clinical relevance: Patients who experience unexpected, albeit transient improvement in myelopathic symptoms who are known or suspected to have arachnoiditis should be evaluated for surgically remediable lesions. Remediation of these lesions can potentially improve long term outcome.
