Contrast-enhanced MRI revealed nodular signals in the pineal, suprasellar region, and fourth ventricle (1.0, 2.7, and 1.1 cm in diameter, respectively) ( Figure 1A ). After the completion of diagnostic radiation therapy of 20 Gy and subsequent radiotherapy(the patient received three-dimensional conformal radiotherapy and the total dose was 40 Gy in fractions of 1.8-2.0 Gy per day, 5 d/wk), the lesions of the suprasellar, the pineal, and fourth ventricle almost disappeared ( Figure 1B ).
