“…The cyst in this case was lined by thin flattened cells of arachnoid rather than by ependyma as in the case of ttamby and Gardner. 5 The fact that this cyst was lined with arachnoid cells calls to mind the cases reported by Bucy, 1 Craig} Kaplan, ~ Thompson, 11 and Trowbridge and French. 13 Each of these authors described cysts in the posterior fossa, causing obstructive hydrocephalus, lined entirely with arachnoid cells.…”

“…Often no cyst-fluid has been obtained for analysis and it is difficult at operation to determine whether or not a small communication exists between the cyst itself and the rest of the subarachnoid space. The cases of Jakubiak et al (1968) and even the tegmental ependyma-lined cyst described by Hamby and Gardner (1935) might have had tiny communications with the CSF pathways. In the latter case, the cyst fluid was similar to ventricular CSF with a total protein content of less than 10 mg per 100 ml and a negative Pandy reaction.…”

SYNOPSIS Three cases of progressive hydrocephalus, two occurring in infants and one in a 12 year old girl who also exhibited precocious puberty, were found to be associated with large arachnoid pouches originating within the posterior fossa. The pathogenesis of such cysts is discussed with special reference to the possibility that their progressive distension results from CSF pulsations of venous origin. Both a direct method of treatment (opening the cyst into the adjacent subarachnoid space) and an indirect one (insertion of a ventriculo-atrial shunt) have been used with success.

“…It is likely that they result from more than one cause. Hamby and Gardner (1935) thought in their case that the cyst had formed from a ventricular diverticulum, but since their patient had suffered a fall they could not exclude trauma as a causative factor. Alexander's (1953) patient had had severe pertussis at the age of 5 months so the cyst could not necessarily be considered congenital in origin.…”

Cummins, Taveras, and Schlesinger (1960) Case Report A 13-month-old boy was admitted to the Syracuse Memorial Hospital on March 29, 1960, because of regression in neuromuscular function and a rapidly enlarging head. The baby had developed normally to the age of 10 months at which time he could stand with help and spoke a few simple words. He then became irritable, slowly lost the ability to stand or sit, and at 12 months developed an internal squint of the right eye.The mother's pregnancy and delivery were uneventful. There was no history of infectious disease in childhood.Physical examination revealed a very irritable child. The skull was enlarged (52 5 cm. maximum circumference), but the scalp veins were flat and no cranial bruit was heard. Neurological examination demonstrated a right abducens palsy, bilateral papilloedema, a positive MacEwen's sign, and severe generalized spasticity and clonus. The blood count and urine analysis were indeterminate. Plain skull films showed widened sutures, an enlarged vault, and a simple linear fracture in the right parietal bone.On the second hospital day subdural taps were performed through the enlarged anterior fontanelle, but no fluid was obtained.Two days later contrast radiographs were obtained. (A detailed description of the pertinent films made during this and subsequent studies is given beneath Figs. I and 2.)A gas ventriculogram was performed first because of 374
