Reason: any change in plexiform mass History: plexiform, NF type 1, pt complaining of daily pain. Again seen is a trans-spatial plexiform mass centered in the left retropharyngeal soft tissues that spans from the level of the nasopharynx into the mediastinum, with extension and left carotid space with associated partial encasement of the great vessels, and into the left visceral space with associated distortion of the thyroid gland. The mass measures up to 4.6 x 3.8 cm in the AP and transverse dimensions, axial series 701 image 11, and is not significantly changed. More superiorly at the level of the oropharynx mass measures 2.0 cm in the short axis, series 701 image 29, which is also not significantly changed. Craniocaudal extension approximately 14 cm is also not significantly changed.Again seen is narrowing of the oropharyngeal airway as well as rightward deviation of the trachea. Partially imaged brain demonstrates multiple T2 hyperintense lesions in the cerebellum, brainstem, and middle cerebellar peduncles, similar to prior. Cervical and upper thoracic spinal canal remains patent.
1. Compared to 8/25/2015 and 3/23/2015, there is no significant change in size of the plexiform neurofibroma centered in the left retropharyngeal soft tissues with extension into the mediastinum. Mass effect on the oropharyngeal airway, rightward tracheal deviation, and partial encasement of the left carotid vasculature again seen. 2. Partially-imaged intracranial stigmata of neurofibromatosis type 1.
