case_images: Preoperative MRI - Hypointense in T1 (red arrow) and hyperintense in T2 (yellow arrow) (A and B); T1 with contrast showed a mild dotted enhancement (blue arrow) in the center of the lesion (C); Hypointense signal on the gradient-echo (T2*) (black arrow - D).

case_images: Contrast enhancement showed mild dotted enhancement inside the mass with a hypointense signal on the gradient-echo (T2*) (Figure 1).
case_images: Histopathological findings of brain biopsy. On hematoxylin and eosin staining, fragments of a biphasic, moderately cellular neoplasm were found, comprised cells with both glial and neurocytic differentiation (A - H&E, 40X). In some areas, there were neurocytic rosettes with an eosinophilic neuropil core (B - H&E, 100X). Immunostaining revealed a strong expression of glial fibrillary acidic protein (C - GFAP, 100X), and perhaps most useful, a strong, granular expression of synaptophysin (D - Synaptophysin, 100X).

case_images: Additionally, neurocytic rosettes with an eosinophilic neuropil core were also found (Figure 2).
case_images: Postoperative MRI - T1 and T1-weighted with no enhancement and no residual tumor. T2 with no recurrence of the tumor and no hydrocephalus.
