This model, when compared to distal catheter complications on a ventriculoperitoneal (VP) shunt, presents similarities that could help understand the mechanism of the nonfunctional complications of the distal VP catheter (complication with functional shunt), providing valuable data to support an inflammatory mechanism.

-Congenital dermoid inclusion cyst over the anterior fontanel (CDIC) is an uncommon cystic lesion located over the anterior fontanel. It is a benign and curative lesion and most of the time, can be diagnosed at birth. From 1994 to 2001, three patients were operated with this kind of lesion and after reviewing the literature we found 229 cases and only 6 cases described in Brazil. Our objective in this study is to report three more cases.KEY WORDS: congenital inclusion, dermoid cyst, epidermoid cyst, anterior fontanel.Cisto dermóide de inclusão congênita sobre a fontanela anterior: relato de três casos Cisto dermóide de inclusão congênita sobre a fontanela anterior: relato de três casos Cisto dermóide de inclusão congênita sobre a fontanela anterior: relato de três casos Cisto dermóide de inclusão congênita sobre a fontanela anterior: relato de três casos Cisto dermóide de inclusão congênita sobre a fontanela anterior: relato de três casos RESUMO -Cisto dermóide de inclusão congênita sobre a fontanela anterior (CDIC) é lesão rara localizada na região da fontanela anterior. Trata-se de lesão benigna e curável que, na maioria das vezes, é diagnosticada no nascimento. De 1994 a 2001, três pacientes foram operados com este tipo de lesão e, através dos dados disponíveis na literatura, verificamos somente 229 casos descritos, apenas 6 descritos no Brasil, o que nos motivou a registrar mais três casos. PALAVRAS-CHAVE: inclusão congênita, cisto dermóide, cisto epidermóide, fontanela anterior. Many different types of lesions over the children's skull exist and some are commonly diagnosed in daily practice. Congenital dermoid inclusion cyst over the anterior fontanel (CDIC) is a rare and benign lesion located over the anterior fontanel. Many children are examinated with lesions over the skull in our hospital. In a recent review of these children, our attention was drawn to three patients with a cystic rounded mass over the anterior fontanel. These three patients showed no neurological abnormality and the diagnosis of CDIC were confirmed by surgery and histological examination. Our literature search found 229 other cases (Table 1) of CDIC worldwide. CASESFrom 1994 to 2001, three patients were operated with a cystic mass over the anterior fontanel, being of different ages and without neurological abnormality at the time. The first patient a three-year-old-white boy. The second patient (Fig 1) a five-month-old-black girl and the third patient (Fig 2) a five-month-old-white boy. All patients were treated with surgery and using the same approach for each of them (Figs 3 to 12 -the second patient shows all the surgical steps, for better illustration). All three patients presented in this paper are similar in all aspects when compared to those in other papers. Two patients were reviewed recently. The first patient (Fig 13 -no photograph prior to surgery) has a learning disability but is not due to the cyst. He was noted to have a small lipoma over the callosal body. The recent photograph shows the cyst has not recurred. ...
