Three cases of peritoneal pseudocysts are reported with guidelines for the diagnosis of this type of complication. The authors point out the value of the following signs: 1--increase of ventricular pressure with worsening of the clinical picture; 2--localized pain in the abdomen; 3--difficulty to depress the capsule; 4--occurrence of subcutaneous collection of CSF around the pathway of the catheter. In some occasions it is possible to palpate the mass of the pseudocyst. The presence of subcutaneous collection of CSF around the pathway of the catheter is an important warning sign of peritoneal pseudocyst and must be differentiated from that originated by the disconnection between the capsule and the catheter. In this condition however, the accumulation of liquid begins in the cervical region. Also in this case the capsule depresses easily. The most precise diagnosis is achieved by X-Ray. The authors describe a method that consists in introducing a needle through the capsule and injecting 8cc of Dimer-X contrast. The catheter and the cavity of pseudo-cyst appear contrasted in the X-Ray film, establishing the definitive diagnosis. The authors discuss the physiopathology of CSF accumulation; once the pseudocyst is formed, the intracranial pressure increases, and the fontanelle bulges, this leads to repeated pumping by the relatives and subsequent rising of pressure within the pseudo-cyst. At this point the patient refers pain at the location of the pseudo-cyst and the CSF tends to lead around catheter. In babies the abdominal pain leads to crying, thus increasing once more the intra-cystic pressure which favors the leakage of CSF from the pseudo-cyst around the catheter.
The authors present a case of spinal cord schistosomiasis which simulated a tumoral lesion determining spastic paraparesis with a sensitive-motor level at T1. The patient was treated with surgery, praziquantel and dexamethasone, with “restitutio ad integrum”. Seven years later the patient presented recrudescence of the symptoms, without a good response to the medication and without a plausible explanation.The authors wonder about the reasons of the low incidence of central nervous system schistosomosis in an endemic area such as the Northeast of Brazil. A brief review of the literature is done.
Nasci no dia 5 de abril de 1931, na cidade de Limoeiro do Norte, Ceará, às margens do Rio Jaguaribe, o maior rio seco do mundo. Meus pais: Miguel Ângelo de Figueiredo e Gesumira Gurgel de Figueiredo. Inicialmente, não pretendia ser médico, mas militar.
Os autores apresentaram um caso raro de um neurinoma cervical em paciente qu vinha apresentando inicialmente sintomas reladionados com hidrocefalia. Os sintomas melhoram inicialmente após a colocação de derivação ventrículo-peritoneal (DVP), embora a tetraparesia progredisse. A TC de crânio pós-operatória mostrou caractér ventricular bem posicionado e normalização do tamanho dos ventrículos. Ressonância magnética da coluna cervical revelou tumor intradural, extramedular, no nível C2-C3. Após a ressecção tumoral, houve importante melhora da tetraparesia. Em casos de hidrcefalia de causa desconhecida, deve-se procurar descartar a exist~encia de tumores intra-raquidianos.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
