A two-month-old girl with a history of an incidental arachnoid cyst in the prenatal period (38 weeks) presented with persistent irritability. A follow-up computed tomographic (CT) scan revealed an enlarged arachnoid cyst with hydrocephalus. We performed craniotomy and fenestration, but the cyst size did not decrease, and hydrocephalus had worsened on a follow-up CT scan performed 13 months after fenestration. The patient was treated with cystoperitoneal shunting. Follow-up magnetic resonance imaging (MRI) performed 5 years later revealed that the arachnoid cyst had decreased in size and that the hydrocephalus had resolved. Enlarging arachnoid cysts are not common, and optimal surgical treatment is uncertain. Based on the features of this case, we believe cystoperitoneal shunting is an advisable surgical intervention for patients with enlarging arachnoid cysts presenting with hydrocephalus.

A 4-month-old female patient admitted because of hydrocephalus. She was premature infant with germinal matrix hemorrhage at gestational period 27 wks. A ventriculoperitoneal shunt with a low-pressure type valve was placed. Follow-up CT scan obtained 3 months after VP shunt placement, revealed a new Lt. middle cranial fossa cyst. The girl was readmitted to hospital at 7 months after VP shunt placement, complaining of lethargy and vomiting. A CT scan was demonstrated a increase in size of a cyst, She subsequently underwent a left-sided pterional craniotomy with partial excision of membrane and cyst fenestration into the basal cisterns. Follow-up CT scan after 18 months revealed reaccumulation of cyst, the girl was reoperated on. After 2 months, the size of cyst was not decreased. Finally, She underwent a cystoperitoneal shunt. Follow-up CT scan after 5 months was demonstrated disappeared cyst and reexpansion of brain parenchyma. We report the development of a symptomatic sylvian fissure arachnoid cyst developed after ventriculoperitoneal shunt.

The simultaneous correction of the hypertelorism and exophthalmos combined with craniosynostosis is very rarely performed operative procedures in the world. The craniosynostosis is the congenital anomaly that designates premature fusion of one or more sutures in either cranial vault or cranial base. Hypertelorism is not a distinct clinical syndrome in itself, but is a physical finding secondary to facial and cranial maldevelopment and it is defined as a increase in the distance between the medial orbital walls. Exophthalmos can occur following the decrease in the size of the orbit in patients with developmental skeletal disorders such as craniofacial synostosis. The authors experienced 9-year-old male patient, who has complex cranio-facial abnormality. The craniosynostosis was oxycephaly type and primary fronto-orbital advancement surgery had been performed in other hospital. The abnormal cranial vault combined with hypertelorism and exophthalmos due to maldeveloped both orbital walls. Surgical correction was obtained by various cranio-fronto-orbital remodeling technique such as calvarial bone craniotomy, fronto-orbital advancement, paramedian resection, medial canthopexy, Tessier-Wolfe three wall orbital expansions. We achieved a quite satisfactory result both functionally and aesthetically in a complex cranio-facial deformity patient by combination and modification of previously developed various cranio-facial plasty technique and hereby report the case with brief discussion and review of literature.

Objective : Earlier reports have revealed that the incidence of posttraumatic hydrocephalus (PTH) is higher among patients who underwent decompressive craniectomy (DC). The aim of this study was to determine the influencing factors for the development of PTH after DC. Methods : A total of 693 head trauma patients admitted in our hospital between March 2004 and May 2007 were reviewed. Among thee, we analyzed 55 patients with severe traumatic brain injury who underwent DC. We excluded patients who had confounding variables. The 33 patients were finally enrolled in the study and data were collected retrospectively for these patients. The patients were divided into two groups: non-hydrocephalus group (Group I) and hydrocephalus group (Group II). Related factors assessed were individual Glasgow Coma Score (GCS), age, sex, radiological findings, type of operation, re-operation and outcome. Results : Of the 693 patients with head trauma, 28 (4.0%) developed PTH. Fifty-five patients underwent DC and 13 (23.6%) developed PTH. Eleven of the 33 study patients (30.3%) who had no confounding factors were diagnosed with PTH. Significant differences in the type of craniectomy and re-operation were found between Group I and II. Conclusion : It is suggested that the size of DC and repeated operation may promote posttraumatic hydrocephalus in severe head trauma patients who underwent DC.

Objective : Hydrocephalus after intracerebral hemorrhage (ICH) is known to be related to poor prognosis and mortality. We analyzed predictors of permanent hydrocephalus in the patients with surgically treated supratentorial ICH. Methods : From 2004 to 2019, a total of 414 patients with surgically treated primary supratentorial ICH were included. We retrospectively analyzed age, sex, preexisting hypertension and diabetes, location and volume of ICH, presence and severity of intraventricular hemorrhage (IVH), and type of surgery. Results : Forty patients (9.7%) required shunt surgery. Concomitant IVH was higher in the 'shunt required' group (92.5%) than in the 'shunt not required' group (67.9%) (p=0.001). IVH severity was worse in the 'shunt required' group (13.5 vs. 7.5, p=0.008). Craniectomy (47.5%) was significantly high in the 'shunt required' group. According to multivariable analysis, the presence of an IVH was 8.1 times more frequent and craniectomy was 8.6 times more frequent in the 'shunt required' group. In the comparison between craniotomy and craniectomy group, the presence of an IVH was related with a 3.9 times higher (p=0.033) possibility and craniectomies rather than craniotomies with a 7-times higher possibility of shunt surgery (p<0.001). Within the craniectomy group, an increase in the craniectomy area by 1 cm² was correlated with a 3.2% increase in the possibility of shunt surgery (odds ratio, 1.032; 95% confidence interval, 1.005-1.061; p=0.022). Conclusion : Presence of IVH, the severity of IVH and decompressive craniectomy were related to the development of shunt dependent hydrocephalus in the patients with ICH. The increasing size of craniectomy was related with increasing rate of shunt requirement.
