Since October 1993 to October 1995, 11 cases of arachnoid cysts in infant of 2 months -14 years old were operated on at the neurosurgical dep of Hanoi Saint-Paul hospital. Results: excellent and good results: 7/11. Relative: 4/11 No death was reported. The author presents an analysis of detailed clinical signs, anotomo - pathology for clinical diagnosis and surgical treatment, and the method of choice for the treatment. The diagnosis must be made early by CT scaning or Echography.

The association of chronic subdural hematoma (CSDH) and arachnoid cyst (AC) is uncommon. We reported 2 juvenile athletes with CSDH associated with AC which occurred in their daily sports activities and reviewed the literature. Both of them were treated surgically, with satisfactory outcome. AC is a common predisposing factor in young patients with CSDH. The complication of intracranial bleeding is an indication for surgical management. Though there are still controversies in the treatment of asymptomatic AC, it is the consensus that the patients with AC should avoid violent sports so as to reduce the incidence of intracranial hemorrhage resulted from head injuries.

Recently, endoscopic procedures have been recommended as the first surgical option for cerebral arachnoid cyst (AC). The author reports seven ACs treated endoscopically and discuss the role of endoscopic fenestration. The age of the patients ranged from two to 62 years. Three ACs were located in the posterior cranial fossa, two in the suprasellar area, one in the middle cranial fossa, and one in the convexity. All cases were examined by cine magnetic resonance (MR) flow study. The patient's symptoms included headache, vomiting, dizziness, problems in balance, visual disturbance, and seizure. The author performed a cysto-cisternostomy or cysto-ventriculostomy via a single burr hole. The follow-up periods ranged from six to 18 months. There was no mortality or morbidity except one case of intracisternal bleeding during endoscopic procedure. Symptoms were relieved in all seven patients. Follow-up imaging studies revealed a decrease in the size or disappearance of the cysts. The results support that the minimal fenestration procedure as possibly as preserving the internal environment is valuable for the management of ACs.

OBJECTIVE: To explore the pathogenetic mechanism of cystic meningioma and the key to its diagnosis and operation. METHODS: Clinical data of 8 patients with cystic meningioma were analyzed retrospectively. The occuring position and cure rate of cystic meningioma were compared with those of solid meningioma in the corresponding period. RESULTS: All patients were subjected to total resection of tumor parenchyma and cystic wall. No operative death and severe complications occurred. The incidence of uppertentorial region of cystic meningioma was higher than that of solid meningioma, and the difference was significant (χ(2)=2.618, P<0.05). The cure rate was not significantly different between cystic meningioma and solid meningioma (χ(2)=0.010, P>0.05). CONCLUSION Removing tumor totally is the key to preventing its recurrence.

Oculomotor cistern is normal anatomic structure that is like an arachnoid-lined cerebrospinal fluid-filled sleeve, containing oculomotor nerve. We report a case of arachnoid cyst in oculomotor cistern, manifesting as oculomotor nerve palsy. The oblique sagittal MRI, parallel to the oculomotor nerve, showed well-defined and enlarged subarachnoid spaces along the course of oculomotor nerve. Simple fenestration was done with immediate regression of symptom. When a disease develops in oculomotor cistern, precise evaluation with proper MRI sequence should be performed to rule out tumorous condition and prevent injury of the oculomotor nerve.

Objective: To examine the clinical effect of simple muscle packing through transnasal sphenoid approach in the treatment of intrasellar arachnoid cyst. Methods: The clinical data of 11 patients with intrasellar arachnoid cyst treated by transnasal sphenoidal approach with simple muscle packing at the Neurosurgery Department of the First Affiliated Hospital of Zhengzhou University from January 2014 to February 2020 were retrospectively analyzed. There were 5 males and 6 females, with a median age of 48 years (range: 23 to 75 years). The clinical manifestations included headache in 6 cases, dizziness in 4 cases, hypo-libido in 1 case, disturbance of consciousness in 1 case, visual impairment in 7 cases and mixed pituitary dysfunction in 5 cases. The enlargement of the sellar fossa was seen in the preoperative MRI images. The enhanced MRI images showed that the cyst wall of the intrasellar arachnoid cyst was not enhanced, and the compression and thinning of the sellar base was seen in the CT images. In 9 cases, the cyst extended suprasellar and the sellar septum was "arched". In 7 cases, the cyst compressed the optic chiasm upward. The cyst walls of all patients were incised through the nasal sphenoid approach under the endoscope, and the muscle was packed after sufficient drainage. The postoperative symptoms, pituitary endocrine function and recurrence of patients were followed up. Results: MRI images of the sellar region in all patients showed significant reduction or disappearance of cysts. Intracranial infection occurred in 1 case and electrolyte disorder in 2 cases, which were relieved after symptomatic treatment. No cerebrospinal fluid rhinorrhea occurred. Postoperative clinical symptoms were completely relieved in 6 cases and partially relieved in 5 cases. Pituitary endocrine function recovered completely in 2 cases and improved significantly in 4 cases. All patients were followed up for 10 to 40 months. One patient found to have a partial recurrence of the cyst 3 months after surgery. Because there were no new symptoms appeared, the follow-up was continued without second operation. Conclusion: Transnasal sphenoidal approach is a feasible method for the treatment of intrasellar arachnoid cyst.

OBJECTIVETo investigate and evaluate the effectiveness of neuroendoscopic therapy for arachnoid cysts of middle cranial fossa.

METHODSFrom January 2004 to June 2009, 32 patients with arachnoid cysts of middle cranial fossa who were treated with endoscopic cystocisternal fenestration were retrospectively analyzed. There were 21 male patients and 11 female patients, aged from 6 months to 39 years. The clinical and neuroradiological presentation, indications, surgical technique, complications, and clinical and neuroradiological follow-up were analyzed.

RESULTSThe cysts were reduced in size in 20 patients and completely disappeared in 4 patients. For the 27 patients with symptoms before operation, the symptoms disappeared in 8 cases and improved in 17 cases after operation. There were asymptomatic subdural hydroma in 4 patients, intracranial infection and incision cerebro-spinal fluid leakage in 1 patient respectively. The complication incidence rate was 18.8%.

CONCLUSIONSEndoscopic fenestration is an effective treatment for symptomatic arachnoid cysts of middle cranial fossa and could be performed as the first surgical choice for these patients.
