“…For the neck segment of the hypoglossal nerve, CT and MR imaging have also been advocated as the primary imaging modalities. [19][20][21] Here, the hypoglossal nerve is assessed indirectly by delineating the muscles innervated by the …”

BACKGROUND AND PURPOSE:The hypoglossal nerve, providing motor innervation for the tongue, can be affected in many diseases of the neck and skull base, leading to dysarthria, dysphagia, and ultimately atrophy of the tongue. We determined the feasibility of direct visualization of the hypoglossal nerve in the neck with ultrasound, testing this technique on healthy volunteers and evaluating it in clinical practice.

“…9 In the radiologic diagnostic work-up, a segmental imaging approach is advised. [19][20][21] The medullary, cisternal, and skull base segments can be well examined with the existing protocols of MR imaging and CT. In the carotid and submandibular spaces, these imaging modalities are also recommended, but the nerve itself is usually not depicted.…”

“…Hypoglossal nerve may be divided into five parts: the medullary, cisternal, skull base, pharyngeal, and sublingual parts [14]. According to Hoshi et al [11] dumb-bell shaped hypoglossal schwannomas are most common 27/54 (50%), followed by intra cranial 17/54 (31.5%).…”

Schwannomas are benign tumor of the schwann cells. These are common in eighth, tenth cranial nerves and parasympathetic chain. Hypoglossal schwannomas are rare. Among the hypoglossal schwannomas the intracranial and dumb-bell shaped schwannomas are frequent but extra cranial hypoglossal schwannomas are rare. We describe a parapharyngeal hypoglossal schwannoma in a 25 years female presenting as slow growing mass in right side of the neck.

“…7 Radiographic methods can define both the cause and the consequences of XIIth nerve dysfunction. 12 If a palpable mass is discovered in the sublingual space, both CT and MRI can be used to examine the area. Neurilemmomas appear on CT scans as we l l -c i r c u m s c ribed, encapsulated, soft tissue masses.…”
