Abstract
INTRODUCTION
Subependymomas are benign intraventricular tumours that most often occur asymptomatically and are found incidentally on autopsy. Symptomatic examples requiring surgical intervention are exceedingly rare.
CASE PRESENTATION
A 55-year-old man with no history of neurological symptoms presented with multiple episodes of loss of consciousness and increasing headaches. MRI revealed a lobulated intraventricular mass centred at the right Foramen of Monro. Obstructive hydrocephalus with localised midline shift and a second lesion were noted. Right frontal craniotomy with total removal via transcortical resection was performed.
DISCUSSION
Symptomatic subependymomas generally present with signs of hydrocephalus due to obstruction of cerebrospinal fluid pathways. There is only one other reported case of multifocal subependymomas in a symptomatic patient. An example of multiple supratentorial subependymomas causing obstructive hydrocephalus has not been previously reported.
CONCLUSIONS
Multiple subependymomas are rare. Judicious surgical management with full excision led to symptomatic improvement in our patient.
