Computed tomography (CT) scan of the brain showed a left middle fossa, Galassi type 3 arachnoid cyst, with bilateral subdural hygroma/hematoma (chronic), bilateral diffuse cerebral edema, and mass effect causing compression of both frontal horns [Figure 1].

Magnetic Resonance Imaging (MRI) of the brain showed bilateral collection in the subdural space, hypo on T1W [Figure 2] and hyper on T2W [Figure 3] images, matching with the intensities of Cerebrospinal Fluid (CSF) with widened Sylvian fissure on the left side and a compressed temporal lobe on the left side, suggestive of arachnoid cyst with subdural hygroma and mass effect.

The postoperative imaging showed resolution of subdural hygroma with small extradural and subgaleal collection of cerebrospinal fluid
