Colloid cyst of the third ventricle presenting with features of Terson's syndrome.

Jacob MK, Anand SK, George P - Middle East Afr J Ophthalmol (2014 Oct-Dec)

Bottom Line: Emergency craniotomy and excision of the cyst was done, and the patient is doing well for the last 18 months after the surgical intervention.The mechanism of this presentation, importance of early investigations, and timely intervention are highlighted in order to avoid serious neurological sequelae.The literature was extensively reviewed for atypical presentations of intraventricular colloid cyst.

ABSTRACT
This report describes a middle-aged man presenting to the ophthalmologist with history of seeing floaters before both eyes since 2-weeks duration. A history of intermittent headache and dizziness of recent onset was elicited on questioning. Ocular examination showed bilateral early papilloedema and mild vitreous hemorrhage. Brain computed tomography (CT) disclosed features suggestive of colloid cyst of the third ventricle in the region of foramen of Monro with moderate hydrocephalus. Emergency craniotomy and excision of the cyst was done, and the patient is doing well for the last 18 months after the surgical intervention. The mechanism of this presentation, importance of early investigations, and timely intervention are highlighted in order to avoid serious neurological sequelae. The literature was extensively reviewed for atypical presentations of intraventricular colloid cyst.

Contrast-enhanced brain CT scan showing a well-defined round hyperdense lesion (arrow head) in the roof of the third ventricle. Lesion is causing obstruction of the outlet foramina of the lateral ventricle and causing moderate hydrocephalus. CT features suggestive of colloid cyst

Figure 2: Contrast-enhanced brain CT scan showing a well-defined round hyperdense lesion (arrow head) in the roof of the third ventricle. Lesion is causing obstruction of the outlet foramina of the lateral ventricle and causing moderate hydrocephalus. CT features suggestive of colloid cyst

Mentions: A diagnosis of bilateral early disc edema with mild vitreous hemorrhage was made, and he was investigated. Contrast-enhanced CT scan of brain showed a well-defined oval nonenhancing hyperdense lesion measuring 2 × 1.9 × 2.3 cm at the anterosuperior aspect of third ventricle bulging through the right foramen of Monro and compressing the left foramen of Monro causing dilatation of both lateral ventricles with cerebrospinal fluid (CSF) seepage [Figure 2]. Fourth ventricle appeared normal. Moderate 0.8-cm midline shift was also seen to the left side.
