(Postural Change Syndrome)

General: Caused by tumors of the third, fourth, or lateral ventricle or by lesions of the midline in the brain.
Ocular: Partial ophthalmoplegia (third nerve paralysis) and gaze paralysis; oculomotor paresis associated with postural change of head or body; amaurosis or transient blindness; flashes of light.
Clinical: Severe paroxysmal headache; nausea and vomiting; vertigo; irregular respiration; apnea; syncope; tachycardia; free-floating cysts within the fourth ventricle may produce intermittent foramen obstruction and Bruns syndrome; Kramer reported a patient with a free-floating cysticercus cyst with this condition.
