Arachnoid cysts are congenital, cerebrospinal fluid (CSF)-filled, intra-arachnoidal lesions that are a common incidental finding on routine brain imaging... Arachnoid cysts are intra-arachnoidal space-occupying lesions containing fluid similar to CSF... His neurological examination was unremarkable and there was no focal neurological abnormality, cranial nerve deficit, or papilledema... He had no significant past medical history... MRI of the brain showed a right middle cranial fossa arachnoid cyst with an associated right-sided subdural hygroma, causing mass effect with ipsilateral ventricular compression and effacement of the convexity sulcal spaces [Figures 1 and 2]... Although the precise pathogenesis of a subdural hygroma in a patient with an intracranial arachnoid cyst is not fully understood, trauma appears to be the most important causative factor... This trauma is often trivial... The majority of arachnoid cysts complicated by subdural hygromas are located in the middle cranial fossa... Our patient had a relatively large middle cranial fossa cyst, which was asymptomatic prior to its rupture... The patient developed symptoms of raised intracranial pressure, following a minor head injury... Though the majority of arachnoid cysts can be managed conservatively, surgical treatment is appropriate, as in our case, when there is an associated subdural hygroma.

Figure 0001: T2W axial images of the brain at different levels show a right middle cranial fossa arachnoid cyst (arrow) with an associated subdural hygroma (arrowheads)

Mentions: An 8-year-old boy presented with a history of intermittent headache and nausea. One week prior to his presentation he had slipped while walking and suffered a mild head injury. There was no history of loss of consciousness at the time of the injury. His neurological examination was unremarkable and there was no focal neurological abnormality, cranial nerve deficit, or papilledema. He had no significant past medical history. MRI of the brain showed a right middle cranial fossa arachnoid cyst with an associated right-sided subdural hygroma, causing mass effect with ipsilateral ventricular compression and effacement of the convexity sulcal spaces [Figures 1 and 2]. The patient underwent surgery, and cyst fenestration and evacuation of the right-sided subdural hygroma were performed. His symptoms resolved immediately and he made an uneventful recovery.
