Acute Hydrocephalus due to Secondary Leptomeningeal Dissemination of an Anaplastic Oligodendroglioma

Figure 1

(a)–(d) Cranial MRI at initial presentation before surgical treatment of right frontal anaplastic oligodendroglioma. (a): axial T1-weighted contrast-enhanced MRI, (b) axial fluid-attenuated inversion recovery (FLAIR), and (c) sagittal T1-weighted contrast-enhanced MRI revealed a hyperintense lesion on the right cingulate gyrus with slight local mass effect (arrows). (d): T2-weighted axial MRI showing regular ventricular size. (e)-(f): MRI at second presentation 8 months after initial surgery. (e): sagittal T1-weighted contrast-enhanced MRI showing meningeal enhancement in the craniocervical junction (arrows). (f): Axial T2-weighted MRI showed marked ventricular enlargement.
