Symptoms And Signs

Arachnoid cysts represent 1% of all intracranial lesions and appear on the arachnoid membrane (subarachnoid space). The etiology and pathogenesis of arachnoid cysts remain unclear and in their majority they are asymptomatic. Due to the developmental origin of arachnoid cysts, these formations can be identified on prenatal fetal imaging. In this report we presented a case of an enlarged suprasellar arachnoid cyst detected incidentally during a routine fetal sonographic examination at 33 weeks of gestation. The cyst remained stable in size prenatally and postnatally without compressive symptoms and signs and the patient has been set under expectant management with serial clinical evaluation and serial imaging of the cyst.

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.

Arachnoid cysts are benign intracranial lesions that are typically diagnosed incidentally. We describe the case of a 56-year-old man who presented with a multiloculated arachnoid cyst of the middle cranial fossa that extended into the sphenoid sinus. The lesion was identified on computed tomography of the head, which had been obtained for an unrelated investigation. However, establishing a definitive diagnosis proved to be difficult. Because the cyst had caused extensive skull base erosion, the patient was managed conservatively with close observation. We report the radiographic progression of this lesion during more than a decade of follow-up, and we review the literature pertaining to the presentation, pathophysiology, and treatment of arachnoid cysts.

✓ Three cases of suprasellar arachnoid cysts in children are described. The importance of differentiating such a lesion from a dilated third ventricle is stressed. The value of computerized tomography with Conray ventriculography in preoperative diagnosis, symptomatology, and choice of treatment are discussed.

Suprasellar Arachnoid Cyst

Object: Arachnoid cysts are developmental space-occupying lesions filled with CSF-like content and surrounded by a membrane resembling arachnoid mater, with controversial etiology and natural history. Endoscopy has been successfully used for decades to treat a variety of pathologies within thecentral nervous system. Methods: Thirteen patients who underwent endoscopic fenestration for treatment of arachnoid cyst were selected for this study. The surgical indications and techniques were reviewed, and surgical success rates and patient outcomes were assessed. Results: Five patients had middle fossa cysts; 2 a posterior fossa cyst; 3 a quadrigeminal cistern arachnoid cyst and 3 a suprasellar arachnoid cyst. Endoscopic management consisted in a cystoventriculostomy in 8 patients and cystocisternotomy in 5 patients. There was neither mortality nor operative morbidity. Discussion: Arachnoid cysts are a relatively benign pathological entity that can be managed by performing endoscopically guided cyst wall fenestrations into the ventricular system or cerebrospinal fluid containing cisterns. Conclusion: Proper patient selection, preoperative planning of endoscope trajectory, use of frameless navigation, and advances in endoscope lens technology and light intensitycombine to make this a safe procedure with excellent outcomes.

Object Arachnoid cysts may occasionally be associated with subdural hygromas. The management of these concurrent findings is controversial. Methods The authors reviewed their experience with arachnoid cysts and identified 8 patients with intracranial arachnoid cysts and an associated subdural hygroma. The medical records and images for these patients were also examined. Results In total, 8 patients presented with concurrent subdural hygroma and arachnoid cyst. Of these 8 patients, 6 presented with headaches and 4 had nausea and vomiting. Six patients had a history of trauma. One patient was treated surgically at the time of initial presentation, and 7 patients were managed without surgery. All patients experienced complete resolution of their presenting signs and symptoms. Conclusions Subdural hygroma may lead to symptomatic presentation for otherwise asymptomatic arachnoid cysts. The natural course of cyst-associated subdural hygromas, even when symptomatic, is generally benign, and symptom resolution can be expected in most cases. The authors suggest that symptomatic hygroma is not an absolute indication for surgical treatment and that expectant management can result in good outcomes in many cases.

We report four cases of surgically treated intracranial arachnoid cysts, one with cyst-peritoneal shunt and three with craniotomy and arachnoid membrane resection. Their classification and etiopathogeny are discussed, and especially the different methods of treatment comparing the drastic complications (adversities) with the favorable solutions in severe clinical cases (plasticity) treated at our institution.

✓ Intracranial arachnoid cysts are relatively rare; it is believed that they account for only 1% of all intracranial space-occupying lesions. When they occur in the intracranial cavity, they usually develop in relation to an arachnoid cistern as a pocket of cerebrospinal fluid within two layers of arachnoid membrane. Five cases of intradiploic arachnoid cysts have been reported, but an arachnoid cyst presenting as an extradural mass has not been described before. The authors present an unusual case of hemorrhage into a massive intracranial extradural arachnoid cyst with no intradural communication.

✓ Two patients are presented in whom cranial arachnoid cysts developed as diverticuli of the arachnoid membrane through small defects in the dura mater, eroded through the inner table, expanded within the diploe, and eroded the outer table of the skull. Based on observations at the time of surgery and the histological examination of these lesions, it is proposed that they are congenital in origin. Previously reported cases of “traumatic arachnoid cyst without fracture,” “intradiploic cerebrospinal fluid fistula,” and “middle fossa pitholes” appear to represent the same pathological process as the lesions reported in this paper. It is proposed that “intradiploic arachnoid cyst” is the most appropriate term by which these lesions should be described.
