“…In fact, up to that date the tumor had been correctly localized in only 18 of 87 cases. Davis [10], Bailey and Davis [1], and Davis and Cushing [9] reported on the physiopathology of the choroid plexus and six cases of choroid plexus papilloma (two of the lateral ventricle and four of the fourth ventricle), all of whom had been operated upon be tween the years 1908 and 1923. The papilloma was totally resected in only case 6, which was one of the two survivors (the other was case 5, in whom only a fragmentary removal had been obtained).…”

This is a report of 22 cases of papillomas of the choroid plexus diagnosed and managed personally by the author. The angiographic diagnosis and extension of choroid plexus papillomas are described, as is the surgical technique for removing these tumors from the lateral, third, and fourth ventricles. Specific attention is given to using the angiogram as the study of choice upon which surgical technique is planned. The diagnosis of choroid plexus papilloma of the lateral ventricle is made by observing the presence of a hypertrophied anterior choroidal artery, a ‘double tumor’ sign with one tumor at the trigone and the other within the temporal or frontal horn, tumor stain at the trigone, and asymmetrical hydrocephalus, generally, with a shift away from the side of the larger ventricle. Posterior fossa papillomas cause symmetrical hydrocephalus and generally have tumor stain located within the mid-line, with the major feeding coming from either the superior cerebellar or the posteroinferior cerebellar arteries. Surgical removal of the tumor should entail an ‘en bloc’ resection following occlusion of the feeding and draining vessels. The tumor should be removed directly when it is in the lateral ventricle and following ventriculocerebral spinal fluid shunting when it is in the posterior fossa.

RESUMO -É feita análise estatística, semiológica, terapêutica e da evolução de 15 crianças portadoras de tumor do plexo coróideo, tratadas cirurgicamente no Serviço de Neuropediatria dos Hospitais das Clínicas (UFMG) e São Francisco de Assis, num período de 15 anos (1981 a 1996). A idade variou de quatro meses a 16 anos, com média de três anos e seis meses, dez tinham menos de dois anos; nove eram do sexo feminino; 14 tinham sinais de hipertensão intracraniana; em todas elas a presença do tumor foi confirmada pelo estudo com tomografia computadorizada; em oito crianças o tumor estava localizado em um ventrículo lateral. Das 15 crianças, 11 necessitaram de derivação ventrículo-peritoneal; a exerese radical do tumor foi possível em 13 das 14 crianças operadas. O diagnóstico anátomo-patológico foi papiloma em 12 crianças e carcinoma nas outras duas. Duas crianças faleceram, uma no sétimo dia de pós-operatório e a outra 12 meses após, com metástases disseminadas pelo sistema nervoso central. É feita revisão da literatura pertinente e dados são comparados.PALAVRAS-CHAVE: papiloma do plexo coróideo, carcinoma do plexo coróideo. Choroid plexus tumorsABSTRACT -This analysis comprises 15 children under 16 years of age, with choroid plexus tumors, seen in the Service of Paediatric Neurosurgery, Hospital das Clínicas and Hospital São Francisco de Assis in Belo Horizonte, Brazil, between 1981 and 1996. The patients were aged between 4 months and 16 years (average of 3 years and a half); 10 were less than 2 years, 9 were female; 14 children had clinical evidence of intracranial hypertension. All the children underwent CT scan and the choroid plexus tumors were clearly demonstrated in 14 of then. In 8 children the tumors were located in one lateral ventricle, 5 in the fourth ventricle and 2 had the tumors in more than one ventricle, 11 children required ventriculo-peritoneal shunt; 14 cases were operated on, 13 with total excision; 2 children died, respectively 7 days and one year after the surgery. Pathological examination revealed papillomas in 12 cases and carcinoma in two cases.KEY WORDS: choroid plexus papilloma, choroid plexus carcinoma.As lesões tumorais do plexo coróideo são raras, representando, em todas as idades, de 0,4% a 0,6% dos tumores intracranianos e de 1,0% a 4,0% dos tumores intracranianos até os 15 anos de idade [1][2][3][4][5][6] . Esta incidência observada nas crianças aumenta quando se analisam menores de dois anos de idade, faixa etária em que aparece a maioria dos tumores desta região 3,4,[7][8][9] . Dentre os tumores, o mais comum é o papiloma, seguido pelo carcinoma do plexo coróideo que ocorre entre 20,0 e 40,0% dos casos 3,7,10

Choroid plexus tumors are most common in the first year of life and are quite large at presentation. Total resection is the treatment of choice, and many children require diversion of the cerebrospinal fluid despite removal of the tumor. Tumor size and associated hydrocephalus present formidable challenges to the pediatric neurosurgeon. The operative approaches as well as other treatment options are discussed.
