Hepatic Liquoric Cyst as a Complication of Ventriculoperitoneal Shunt Insertion: A Case Report

Background The ventriculoperitoneal shunt (VPS) procedure is still themost used technique for management of hydrocephalus. This article reports a case of hepatic cerebrospinal fluid (CSF) pseudocyst as a rare, but important, complication of the VPS insertion. Case Description An 18-year-old male presented to the hospital complaining of temporal headache and visual turbidity for approximately 3 months with a history of VPS insertion for treatment of hydrocephalus and revision of the valve in adolescence. The diagnosis was based on abdominal imaging, demonstrating an extra-axial hepatic CSF pseudocyst free from infection. Following the diagnosis, the management of the case consisted in the removal and repositioning of the catheter on the opposite site of the peritoneum. Conclusion The hepatic CSF pseudocyst is an infrequent complication of VPS procedure, but it needs to be considered when performing the first evaluation of the patient. Several techniques are considered efficient for the management of this condition, the choice must be made based on the variables of each individual case.

Aspectos clínicos e evolutivos da hidrocefalia na neurocisticercose / Clinical and evolutive aspects of hydrocephalus in neurocysticercosis

Com o propósito de analisar os aspectos clínicos da hidrocefalia (HDC) na neurocisticercose (NCC), realizou-se o estudo retrospectivo de 47 prontuários de pacientes com HDC e NCC. Verificou-se que 70,2 por cento eram homens, entre 21 e 50 anos. A hipertensão intracraniana (HIC) ocorreu em todos os pacientes, cefaléia (CEF) em 89,4 por cento, meningoencefalite (ME) em 80,8 por cento e distúrbios psíquicos (PSI) em 74,5 por cento. A síndrome liquórica da NCC foi detectada em 65,9 por cento pacientes. Além da HDC, as tomografias computadorizadas de crânio (TC) mostraram lesões císticas e edema cerebral difuso em 59,6 por cento cada, calcificações em 55,3 por cento. Dos 41 pacientes (87,2 por cento) com derivação ventriculoperitoneal (DVP), em 22 (53,7 por cento) deles foram necessárias uma a sete revisões/paciente (média=3). A evolução foi satisfatória em 51,1 por cento e fatal em 31,9 por cento. Conclui-se que a hidrocefalia é mais comum no sexo masculino em idade produtiva, tendo a HIC, CEF, MN e PSI como manifestações freqüentes e que, a necessidade de revisões de DVP, piora o prognóstico.

With the purpose to verify clinical aspects of hydrocephalus (HC) in patients with neurocysticercosis (NCC), a retrospective study of 47 patients was performed. The majority of patients (70.2 percent) were men aging 21-50 years. Intracranial hypertension (ICH) occurred in all patients, headache (HA) in 42 (89.4 percent), meningoencephalitis (ME) in 38 (80.8 percent) and psychiatric disorders (PD) in 34 (72.3 percent). The cerebrospinal fluid syndrome of NCC was detected in 31 patients (65.9 percent). In addition to HC, computed tomography (CT) scans showed cystic lesions in 28 (59.6 percent) patients, diffuse brain edema also in 28 (59.6 percent), and calcifications in 26 (55.3 percent). Shunts were inserted in 41 (87.2 percent) patients and 22 (53.7 percent) of them were submitted to 1-7 surgical revision/patient (mean=3) that were higher (mean=4) in those who died than in survivors (mean=2). Evolution was satisfactory in 24 (51.1 percent) patients and fatal in 15 (31.9 percent). It is possible to conclude that, in patients with NCC, HC occurs predominantly in men in productive life with ICH, HA, ME and PD as common manifestations, and the need for shunt revision makes patient's prognosis worse.

Cerebrospinal fluid, sodium, potassium and bicarbonate concentrations in congenital hydrocephalus children

The objective of this investigation is to throw the light on the biochemical changes of cerebrospinal fluid electrolytes, sodium, potassium and bicarbonate in normal control and congenital hydrocephalus CSF samples of children, their ages ranged from 0.6 to 3 years]. These electrolytes regulate hydration and dehydration intracellular. The results revealed a nonsignificant decreasing of sodium with slightly decreasing in potassium and bicarbonate compared with control CSF samples. Although there is a significant decrease in Na + and K + [P <0.01] and Na+/HCO3 [P <0.01] in hydrocephalus patients, while insignificant decreasing of K + and HCO3 in the same patients. The results suggested that decreasing of CSF electrolytes is relatively to defect of brain membrane permeability or humoral contribution
