The patient’s mother reports that there are several “light spots” on the patient’s trunk that have been slowly increasing in number. The lesions are not painful nor pruritic. The patient’s mother is worried because her nephew had vitiligo. The patient reports that he feels “fine,” but reports occasional headaches and increasing difficulty with seeing the board at school. In addition to the patient’s cousin having vitiligo, the patient’s paternal grandfather and uncle have bilateral deafness, and his mother has systemic lupus erythematosus.

On physical examination, there are multiple, discrete, 2-3 cm hypopigmented macules on the chest, abdomen, back, and posterior shoulders. Which of the following head and neck computed tomography findings is the patient most likely to develop?
