Giant cell arteritis and bilateral peroneal nerve palsy

Acute bilateral foot drop in a chronic alcoholic patient

Peroneal palsy is compression neuropathy of the peroneal nerve, which presents with foot drop. Patients with unilateral peroneal nerve palsy are frequently encountered in clinical practice. Although bilateral peroneal nerve palsy is rare, bilateral foot drop due to peroneal nerve palsy is much less common. The main complaint is often walking difficulty due to weakened ankle dorsiflexor muscles. Medical history and physical examination are always a part of the diagnosis, and the most useful method is electroneuromyography to evaluate the degree of the lesion. In this report, we present a 52-year-old male unconscious patient with chronic alcoholism admitted with acute bilateral foot drop and discuss clinical assessment, diagnosis, and treatment planning of this rare case of peroneal palsy after lying in the prone position in the light of literature data.

Vasculitic neuropathy

Vasculitis is a primary phenomenon in autoimmune diseases such as polyarteritis nodosa, Wegener's granulomatosis, Churg-Strauss syndrome, microscopic polyangiitis, and essential mixed cryoglobulinemia. As a secondary feature vasculitis may complicate, for example, connective tissue diseases, infections, malignancies, and diabetes. Vasculitic neuropathy is a consequence of destruction of the vessel wall and occlusion of the vessel lumen of small epineurial arteries. Sometimes patients present with nonsystemic vasculitic neuropathy, i.e., vasculitis limited to peripheral nerves and muscles with no evidence of further systemic involvement. Treatment with corticosteroids, sometimes in combination with other immunosuppressants, is required to control the inflammatory process and prevent further ischemic nerve damage.
