The association between arachnoid cyst and subdural hygroma (SH) is rare. We report a case, presenting of left middle cranial fossa arachnoid cyst with traumatic SH and spontaneous resolution of SH. The patient was totally asymtomatic prior to the injury and his arachnoid cyst was detected incidentally during investigations following minor head trauma. Our case with normal neurological examinat...

Chronic subdural hematomas (CSHs) are generally regarded to be a traumatic lesion. It was regarded as a stroke in 17th century, an inflammatory disease in 19th century. From 20th century, it became a traumatic lesion. CSH frequently occur after a trauma, however, it cannot occur when there is no enough subdural space even after a severe head injury. CSH may occur without trauma, when there is s...

We reviewed serial computed tomographic (CT) scans of 58 patients with traumatic subdural hygroma (SDG) to investigate its natural history. All were re-evaluated with a special reference to the size and density of SDG. Thirty-four patients (58.6%) were managed conservatively and 24 patients (41.4%) underwent surgery. The lesion was described as remained, reduced, resolved, enlarged and changed....

arachnoid cysts are congenital lesions arising from the arachnoid membrane. the incidence of arachnoid cysts in the general population is around 0.1% and their most common location is the middle fossa. arachnoid cysts usually present during the childhood and are identified incidentally. when symptomatic, the most common presentations include headache and seizure. the popular treatment for this ...

OBJECTIVE Brain atrophy and subdural hygroma were well known factors that enlarge the subdural space, which induced formation of chronic subdural hematoma (CSDH). Thus, we identified the subdural volume that could be used to predict the rate of future CSDH after head trauma using a computed tomography (CT) volumetric analysis. METHODS A single institution case-control study was conducted invo...
