Ultrasound measurement of median and ulnar nerve cross-sectional area in acromegaly.

Context: Acromegalic patients may complain of sensory disturbances in their hands.

Objective: Our objective was to examine median (MN) and ulnar nerves (UN) of acromegalic patients with ultrasound (US) and to determine whether nerve abnormalities correlate with clinical parameters and nerve conduction studies (NCS).

Patients: We prospectively examined the MN and UN in 34 nondiabetic, acromegalic patients (18 females and 16 males; age range 18-79 yr) and 34 sex-, age-, and body mass index-matched controls with 17-5 MHz US.
