Fifty-year-old man presented with two, tender, cord like, and non-pulsatile swellings on the right side of neck of 1 month duration and right-sided facial palsy affecting the lower half of face of 2 weeks duration [Figure 1]. We noted a hypoesthetic, erythematous patch (7 × 6 cm) on the right side of the lower half of cheek extending to the neck [Figure 1]. Histopathology confirmed borderline tuberculoid leprosy with Type 1 lepra reaction [Figure 2]. Considering the possibility of grossly enlarged great auricular and transverse cervical nerves appearing as cord like swellings, we did a high resolution ultrasound (HRUS) imaging, which revealed [Figure 3] two grossly enlarged fascicles of great auricular nerve (cross-sectional area 55mm2), underscoring the importance of HRUS in evaluation of peripheral nerves in leprosy.
