When the relationship between the location and hydrocephalus was compared, the patients with tumor in the lateral ventricle or the third ventricle suffered higher rates of severe hydrocephalus than those with tumor in the fourth ventricle
(lateral ventricle: 51.7%, 30/58; third ventricle: 47%, 8/17; fourth ventricle
: 11.1%, 2/18; ?

Cranial CT showed bilateral ventriculomegaly (Figure 1), enlarged third ventricle, enlarged fourth ventricle
with posterior fossa cyst (Figure 2), and cerebellar hypoplasia (Figure 3), which was consistent with his previous cranial MRI.

(b) Coronal T2 weighted images showing central necrosis of the mass and compression effect over the fourth ventricle
In the present patient, compression from the meningioma extended to and around the basal ganglia as well as the cerebellum and deformed the fourth ventricle
. It may be likely that the effect of the mass on the basal ganglia led to the OCD symptoms.
Noncontrast CT imaging of the head performed in the ER demonstrated a roughly 6 cm mass centered in the superior right cerebellar hemisphere with cortical involvement and mild mass effect upon the fourth ventricle
. A solitary punctate superficial focus of hyperdensity was seen, deemed equivocal for focal hemorrhage or dystrophic calcification.

The second mechanism involves large amounts of aneurysmal SAH regurgitating into the fourth ventricle
via the foramina of Luschka.
Despite external lumbar and ventricular (both lateral ventricles and fourth ventricle
) CSF drainage, her neurologic condition deteriorated.
The rostral opening of the mesencephalic aqueduct was slightly dilated, but no enlargement of the lateral extensions of the aqueduct or the fourth ventricle
was observed (Fig 1).
