Arachnoids cysts (AC) are non-tumoral and congenital lesions and constitute 1% of all intracranial space occupying lesions . Ninety percent of ACs is located in the supratentorial region and 10% are in the posterior fosse . The middle cranial fosse is the most common place of the ACs (60%) other sites include seller region, cerebral convexity, and quadrigeminal plate. The clinical signs and symptoms of ACs are relegated with their size, anatomic location and influence on the cerebrospinal fluid (CSF). Symptomatic ACs is usually diagnosed in the first or second decades of life due to increased intracranial pressure, craniomegaly or developmental delay. The definition of meditational goiter (MG) generally refers to a stoma with location for at least 50% of its volume in substernal position . MG is a rare disease that generally diagnosed incidentally, and up to 40% of MGs are asymptomatic . They may cause compressive symptoms in the surrounding tissues if they are large enough.
