A computed tomography scan showed a high-density mass in the third ventricle and ventricular dilatation [Figure 1a]. The mass lesion exhibited homogenous enhancement with perifocal edema [Figure 1b]. T1-weighted image showed that a solitary mass lesion was located in the third ventricle with attachment to the roof of the third ventricle [Figure 1d-f]. The T2-weighted star image showed the lesion as a hypo-intense mass that indicated the intratumoral hemorrhage [Figure 1c]. The intraoperative findings showed that the tumor was elastic hard, hemorrhagic-, and attached to the velum interpositum [Figure 1g and h]. A postoperative enhanced magnetic resonance imaging showed improvement of the hydrocephalus and total removal of the tumor [Figure 1i]. As of 2 years after surgery, follow-up enhanced magnetic resonance imaging showed no recurrence [Figure 1j-l] and the postoperative KPS showed as a score of 100 in a independent manner, the patient has been doing well.
