A 47-year old male presented with progressive morning headaches for a total of 10 days, which was associated with nausea and vomiting. He had no history of trauma or loss of consciousness.
Interestingly, an 11-year-old girl with a long history of headache was referred to undergoing a brain MRI. The MRI was performed with 1.5 Tesla Siemens machine.\nA well-defined rounded abnormal signal intensity lesion was visualized at the foramen of Monro resulting in moderate acute hydrocephalus. The lesion was isointense to gray matter on T2WI and hyperintense on T1WI and FLAIR images. No drop of the signal was visualized in T2 GRE sequence to suggest intralesional hemorrhage. No diffusion restriction was noted. Subtle enhancement of the lesion was seen on postcontrast images (Figures and ).\nThe first case did not receive any surgical treatment and, after ten months of follow-up, he claimed that the symptoms have diminished. The second case was lost of follow-up.
