Mesencephalic developmental venous anomaly causing obstructive hydrocephalus: illustrative case

Kota Hiraga, Shigemasa Hayashi, Ryosuke Oshima, Tatsuma Kondo, Fumiaki Kanamori, and Ryuta Saito

axial T1-weighted MR image showing that the bilateral temporal horns and third ventricle are dilated. The Evans index is 0.44. B: Preoperative sagittal T1-weighted contrast-enhanced MR image. The DVA directly above the cerebral aqueduct is observed as the abnormal distended linear region with enhancement ( yellow arrow ). The fourth ventricle is not dilated. An enhancing structure within the frontal horn is aliasing. C: Preoperative digital subtraction angiography shows a mesencephalic DVA ( red arrow ). The patient underwent endoscopic third ventriculostomy

Sinus pericranii in the setting of a posterior fossa pilocytic astrocytoma: illustrative case

Youngkyung Jung, Jennifer L. Quon, and James M. Drake

postoperative magnetic resonance venogram (MRV), likely secondary to reduced compression ( Fig. 3 ). However, the patient continued to have high EVD output, and we decided to proceed with an endoscopic third ventriculostomy, as there was some reluctance in passing a shunt tunneler near the venous network. Pathological evaluation by frozen section was consistent with a pilocytic astrocytoma. FIG. 3. Postoperative axial ( A ) and sagittal ( B ) T1-weighted MRI with contrast demonstrating interval resection of lesion with improved hydrocephalus and mass effect of fourth

Terson syndrome secondary to aneurysmal subarachnoid hemorrhage in a child: illustrative case

Jacob M. Mazza, Parth Tank, Melissa A. LoPresti, Jonathan P. Scoville, Brenda L. Bohnsack, and Sandi Lam

patient was treated in the pediatric intensive care unit for EVD management and monitoring for vasospasm. The patient’s course was complicated by fungal meningitis treated with antimicrobial therapy for 21 days and subsequent endoscopic third ventriculostomy for hydrocephalus treatment. On post-bleed day 20, when the patient’s condition had improved to the point that he was able to verbally communicate, he reported decreased vision in his left eye. The visual acuity was 20/30 in the right eye, and he only had the ability to detect hand motion in the left eye. There were
