“…Psammoma bodies are as well scattered in the arachnoid mater as in the glomus choroideum (Shuangshoti and Netsky, 1970). The mode of formation of these calcospherites has been debated, but it has been suggested that they are related to the calcification occurring in degenerated meningocytic whorls (Shuangshoti and Netsky, 1970 (Soule and Whitcomb, 1946;Taveras and Ranshoff, 1953;Starkman et al, 1958). Moreover, an old subdural haematoma may become cystic especially when the large clot is partly absorbed; a subdural cyst with inner and outer neomembranes is formed and may be calcified (Merritt, 1973).…”

ThailandS U M M A R Y Two unique findings, advanced calcification and ectopic neuroglia, were encountered in the wall of a giant congenital arachnoid cyst occurring in a 40 year old woman. The cyst almost totally filled the supratentorial subdural space of the left hemicranial cavity, was not connected with the subarachnoid space, and thus developed intra-arachnoidally. Its congenitally derived nature was supported by the unique finding of heterotopic neuroglia in the wall. Congenital arachnoid cyst must be distinguished from various cystic lesions within the central nervous system, including the neuroepithelial cyst which can arise throughout the neuraxis. It is suggested that pathogenesis of the congenital arachnoid cyst is related to aberrant flow of the ventricular cerebrospinal fluid into the developing leptomeninx in the process of differentiation of the subarachnoid space. The tract or pouch may occur within the arachnoid mater, and the cyst is formed intra-arachnoidally when the former filled with fluid is closed off from the subarachnoid space. Arachnoid cyst is rare within the cranium. Only four cysts were found among 1028 intracranial tumours in Thailand reported by Shuangshoti and Panyathanya (1974), a proportion of about 0.4% of intracranial neoplasms. We subsequently encountered an additional example of extensively calcified intracranial arachnoid cyst with ectopic neuroglia in the wall. As no reports could be traced in the medical literature of calcified arachnoid cyst and as ectopic neuroglia was present in the cyst wall, the case is reported as unique.Case report A 40 year old woman was admitted to hospital in coma. According to her son, she had had fever for four days before admission. Two days later, she complained of headache, dyspnoea, and pain in the chest. Subsequently, consciousness had deteriorated, and eventually she became comatose. The patient had had occasional headache in the past. There was no history of cranial trauma.On admission, her body temperature was 38.5°C pulse rate 140/min, respiratory rate 40/min, and

“…Importantly, they were not leptomeningeal cysts (Taveras & Ransohoff, 1953), which, given the CSF-like contents, position, and trauma undergone by Cases 1 and 2, is the most likely alternative. Leptomeningeal cysts form when a traumatic brain injury leads to extensive tissue loss and the gathering of fluid in the subarachnoidal space; they are clearly distinguishable from developmental arachnoid cysts, since there is no blocking of drainage.…”

“…[2][3][4][5][6][7] The risk of an intracranial hematoma is about 12 times higher among patients with a skull fracture than among other patients. [8][9][10][11] Skull fracture may also be complicated by leptomeningeal cyst, 12 growing fracture 13 or displaced fracture. 14 Even though growing fracture is uncommon (2% of all fractures), its detection is important because of the risk of brain hernia if left undiscovered.…”
