The cranial MRI of the head revealed a massive mass in the third ventricle. (A) The lesion was isointense on T1-weighted image. (B) The lesion was hyperintense on T2-weighted image. (C) After enhancement injection, the lesion in the third ventricle was significantly enhanced. (D) Sagittal view showed a "cauliflower-shaped" lesion after enhancement.

Cranial magnetic resonance imaging (MRI) showed the presence of a space-occupying lesion in the third ventricle, about 3.8x4.6x3.1 cm in size, isosignal at T1 and mild high signal at T2-weighted images, accompanied with severe hydrocephalus ( Figures 1A, B ). Contrast-enhanced lesions showed "cauliflower-like" appearance on MRI ( Figures 1C, D ).
Intraoperative and postoperative conditions. (A) Appearance of the head during the surgical treatment. (B) Microscopic resection of the tumor by right frontal cortex fistula. (C) Exposure of optic nerve revealed after the tumor resection by microscope and endoscopic "chopstick" technique. (D) The recovery of the infant before discharge from the hospital. (E) Front view of the endoscopic "chopstick" technique. (F) Behind view of the endoscopic "chopstick" technique.

Right frontal cortical fistula was performed to remove a part of the tumor under the microscope, and the tumor in the blind area of the microscope's visual field was removed by the endoscopic "chopstick" technique ( Figures 2A-C, E, F ). The child recovered well after surgery ( Figure 2D ).Histopathological examination of the resected tumor papillary-like architecture that has fibrovascular cores, resulting in a diagnosis of CPP (WHO Grade 1) ( Figure 3C ).
(A, B) Postoperative cranial MRI scan indicates total tumor resection. (C) Micrograph shows tumor papillary-like architecture that has fibrovascular cores (H and E, x200).

The child recovered well after surgery ( Figure 2D ).Histopathological examination of the resected tumor papillary-like architecture that has fibrovascular cores, resulting in a diagnosis of CPP (WHO Grade 1) ( Figure 3C ). After 1 month of follow-up, MRI indicated no residual tumor ( Figures 3A, B ).
