Ultrasound of the Month – Case 156


Diagnosis: Parsonage-Turner syndrome (Neuralgic amyotrophy) Parsonage-Turner syndrome is a neurological disorder classically presenting with denervation in the upper extremity after an acute onset of intense pain. The pathophysiology of Parsonage-Turner syndrome is considered multifactorial and probably immune-mediated, although the exact cause or trigger is still uncertain. The clinical history is important for diagnosis. On MRI and ultrasound, diffuse enlargement of the affected nerve with hourglass-like constrictions is highly suggestive of Parsonage-Turner syndrome. If the patient has residual symptoms after conservative therapy, surgical neurolysis at the sites of hourglass-like constrictions may be of benefit.
