Within the cervical spine there are innumerable, bilateral extramedullary, intradural masses, many of which extend through the intervertebral foramina, extending into the perivertebral muscles. These are characterised by intermediate low T1, intermediate - heterogeneous but largely high T2 signal and homogenous contrast enhancement, consistent with schwannomas.
Further 3.3 cm rounded lesion of similar signal characteristic lies at the left base of the tongue, also demonstrates homogenous contrast enhancement (greater than the thyroid tissue), and likely represents a large schwannoma rather than complicated ectopic thyroid tissue. This markedly narrows the oropharynx, which is slit-like and measures 5mm at its maximal dimension. ENT assessment is suggested.
Multiple other masses of similar signal characteristics are seen within the carotid vessels, and deep to both sternocleidomastoid muscles. Within the thoracolumbar spine, innumerable extramedullary, intradural schwannomas are identified, the largest of which extends through the right T3/4 intervertebral foramen measuring 3.6 x 2.9 (w x AP) cm. This demonstrates internal low T1 and high T2 signal without contrast enhancement, consistent with cystic degeneration. Within the lumbar spine, the intrathecal space is moderately narrowed at L4.
Smaller schwannomas are seen within the right subcutaneous tissues, one adjacent to the right rib and many within the lumbar plexus.
Innumerable schwannomas in keeping with neurofibromatosis type 2.
