A & A case reports
-
A 30-year-old man developed unexplained rhabdomyolysis, persistently increased creatine kinase and severe debilitating muscle cramps. After a nondiagnostic neurologic evaluation, he was referred for a muscle biopsy, to include histology/histochemistry, a myoglobinuria panel, and a caffeine halothane contracture test. ⋯ His identical twin brother, who was suffering from similar complaints, was found to share the same mutation. They each require oral dantrolene therapy to control symptoms, despite difficulty in identifying health care providers familiar with treating this disorder.

Below-knee amputation neuromas may be hard to detect radiographically. This case report demonstrates that in a below-knee amputee with negative imaging but with classic neuropathic pain, successful diagnostic ultrasound-guided nerve-selective peripheral nerve block may be performed to diagnose the problem; subsequent resection of the neuroma may relieve severe neuropathic pain.

A 74-year-old man presented for outpatient endoscopy because of dysphagia and the sensation of a mass in the back of his throat. Esophagogastroduodenoscopy demonstrated a soft tissue mass in the proximal esophagus that prolapsed into the hypopharynx on withdrawal of the endoscope. ⋯ The patient was transferred to the hospital for further treatment. Surgical resection revealed a rare giant fibrovascular polyp, which may be associated with asphyxiation and sudden death.

Pneumocephalus may occur after inadvertent injection of air into the subarachnoid space while performing epidural anesthesia using a loss-of-resistance technique with air in the syringe. We report a case of pneumocephalus after an interlaminar epidural steroid injection using the loss-of-resistance to air technique. In this report, we examine the etiology, the expected course of symptoms, and resolution, as well as treatment, of pneumocephalus following a systematic literature review.
