Intraparenchymal supratentorial arachnoid cyst: a case report

Abstract

Background: Intracranial arachnoid cysts are collections of cerebrospinal fluid within the arachnoid membrane and subarachnoid space of the cisterns and major cerebral fissures that account for about 1% of all intracranial lesions. Expansion of the cyst and compression on surrounding structures may became symptomatic, which reflects its size and anatomic distribution. Case presentation: Here, we present a very rare case of patient with supratentorial intraparenchymal arachnoid cyst placed in the left frontal lobe without any communication with the subarachnoid space and ventricle and presented with clinical symptoms. The patient underwent fenestration of the lesion and was clinically improved. Conclusions: Although the etiology and the enlargement mechanism of arachnoid cysts remain unclear, both conservative and surgical treatments are optional. According to size, anatomical location, neuroimaging, and clinical symptoms, an arachnoid cyst should be included in the differential diagnosis of primary intracerebral cysts.

Notions of Temporalities in Artistic Practice

“…I miss it … I miss it… because we don't have a city hotel anymore and everything else is a poor substitute. The younger generation will not be as fortunate as we were, that is certain (Dlaka, 2019). (Fig.…”

“…"If some of his hotels did not have a roof, we would not even perceive them as volumes", writes architect Ivana Nikšić Olujić in her book ZDRAVKO BREGOVAC: arhiv arhitekt8 (Korbler, 2015). The art historian Irena Dlaka emphasises that not only did the architects of post-war modernism in Yugoslavia, especially in the 1960s, show respect for what was already there, but that the hotel employees themselves, who were also co-owners of the hotel, were very careful and "tender" with the already existing plants when designing the green spaces such as the park atrium of the Hotel Helios: "[…] the plants that were found got their openings in the roofs […]"9 (Dlaka, 2019).…”

Arachnoid cyst presenting as a neurosurgical emergency: a case report

“…Arachnoid cysts tend to form within the subarachnoid space and arachnoid membrane of the major cerebral fissures and arachnoid cisterns, with the sylvian fissure being the most common location. Along with these areas, the quadrigeminal plate, sellar and suprasellar regions, quadrigeminal cerebellopontine angle, posterior infratentorial midline cisterns, and convexities of the brain are other potential sites 13 – 15 .…”
