A 23yo female patient with neurofibromatosis syndrome because she has got sebaceous adenomatosis around her nose, has usually loss of her vision in short time for 2 months without headache nor nausea.
Ultrasound detected edema of optic disc in both 2 eyes and optic nerve sheath diameter on right and left ocular in 5.1 and 5.5mm, respectively.
Funduscopy of 2 oculars confirmed papilla in edema but the ocular pressures were still in normal values.
A suggestion of elevated intracranial pressure was established.
MDCT showed a choroid plexus tumor of 30mm in diameter which made secondary obstruction of the cerebral ventricle and raising intracranial pressure, into left ventricle with calcification close by the interventricular foramen.
So, increasing measurement of ONSD and edema of papilla in ophthalmology ultrasound could lead more investigation to diagnose a brain tumor in a neurofibromatosis patient.
