Aspiración estereotáctica de una larva de Spirometra spp. / Stereotactic aspiration of Spirometra mansonides larvae

Brain sparganosis is a non-common parasite infection by Diphyllobothrium or Spirometra mansonoides larvae. This last one is responsible for most of the infestations in humans. We report a 19 years male patient bearer of a brain sparganosis. The patient presented with headache and left hemiparesis. CT diagnosis of right thalamic lesions was made and aspiration biopsy was performed using stereotactic system, obtaining a whole and death larvae. Histopathology confirms a CNS parasitism and it was treated initially with albendazol. ELISA test confirmed Spirometra spp. infestation. The patient developed asymptomatic with total remission of the lesions. It constitutes the second report in Cuba of brain sparganosis.

Se presenta el caso clínico de un varón con 19 años de edad y el diagnóstico de una esparganosis cerebral. Consultó por cefalea y una hemiparesia izquierda. En una tomografía computarizada cerebral con contraste se observaron lesiones talámicas derechas. Se realizó una biopsia cerebral guiada por estereotaxia con aspiración completa de un verme. En el estudio histopatológico se planteó un probable parasitismo de SNC y fue tratado inicialmente con albendazol. Se confirmó la infección por Spirometra spp. por test de ELISA. Evolucionó con regresión de síntomas y remisión imagenológica de las lesiones. Este caso constituye el segundo reporte en Cuba de una infestación cerebral por este parásito y aspiración estereotáctica de la larva de Spirometra spp.

Brain schistosomiasis in mice experimentally infected with Schistosoma mansoni

Introduction Human neuroschistosomiasis has been reported in the literature, but the possibility of modeling neuroschistosomiasis in mice is controversial. Methods In two research laboratories in Brazil that maintain the Schistosoma mansoni life cycle in rodents, two mice developed signs of brain disease (hemiplegia and spinning), and both were autopsied. Results S. mansoni eggs, both with and without granuloma formation, were observed in the brain and meninges of both mice by optical microscopy. Conclusions This is the first description of eggs in the brains of symptomatic mice that were experimentally infected with S. mansoni. An investigation of experimental neuroschistosomiasis is now feasible. .

Monitoring of parasitic cysts in the brains of a flock of sheep in Egypt / Monitoramento de cistos parasitários no cérebro de um rebanho de ovinos no Egito

Cerebral parasitic cysts constitute a major problem for livestock. Among these, coenurosis and toxoplasmosis are predominant. Here, a total number of 60 sheep obtained from a private farm in Suez province, Egypt, were examined postmortem to detect visible parasitic cysts, and microscopically to detect small-sized entities. Necropsy revealed bladder-like cysts measuring 0.5-6.5 cm in diameter that were filled with a translucent fluid containing a large number of protoscolices. Accordingly, the cysts were identified as the metacestode Coenurus cerebralis. Among the sheep examined, 11 animals (7 males and 4 females) (18.3%) were infected. Most of the cysts were located in the cerebral hemispheres, with numbers ranging from one to three per infected animal. The effect of the presence of cysts in the brain tissue was evaluated. Histopathologically, pseudocysts of the apicomplexan Toxoplasma gondii were found in two animals with no detectable inflammatory cell reactions. In conclusion, coenurosis and toxoplasmosis are serious parasitic problems that play a significant role in sheep management in Egypt, as a result of close contact between livestock and dogs and cats, which play a critical role in the life cycle of these parasites.

Cistos cerebrais parasitários constituem um grande problema para o gado. Entre estes, coenurosis e toxoplasmose são predominantes. Aqui, um número total de 60 ovelhas obtidas em uma fazenda particular na província Suez, Egito, foram examinadas post-mortem para a detecção de cistos parasitários visíveis e microscopicamente para detectar cistos de pequenas dimensões. A necropsia revelou cistos medindo entre 0,5-6,5 cm de diâmetro, preenchidos com um fluido transparente, contendo um grande número de protoscolices. Por conseguinte, os cistos foram identificados como o metacestóide Coenurus cerebralis. Entre as ovelhas examinadas, 11 animais (7 machos e 4 fêmeas) (18,3%) estavam infectados. A maior parte dos cistos estavam localizados nos hemisférios cerebrais, com números variando de um a três em ovinos infectados. O efeito da presença de cistos no tecido do cérebro foi avaliado. Histopatologicamente, pseudocistos de Toxoplasma gondii foram encontrados em dois animais sem reações inflamatórias detectáveis. Em conclusão, coenurosis e toxoplasmose são graves problemas parasitários que desempenham um papel significativo no manejo de ovelhas no Egito, como resultado do contacto íntimo dos animais com os cães e gatos, que desempenham um papel crítico no ciclo de vida desses parasitas.

Esparganosis cerebral: Presentación de un caso pediátrico / Cerebral sparganosis in a child: Case report

Se presenta el caso de un niño de 8 años con antecedentes de epilepsia en quien el examen anatomopatológico del material extraído de una lesión de 2,5 por 3 cm localizada en la zona corticosubcortical del lóbulo occipital derecho reveló la presencia de un proceso inflamatorio crónico granulomatoso con una larva de Spirometras pp. El paciente nació y vivió varios años en una zona rural de Tarija (Bolivia). Es el primer ejemplo pediátrico de esta infestación parasitaria a nivel cerebral reconocido en la Argentina.

We are reporting the case of an 8-year-old boy with history of seizures in whom the pathology exam of 2.5 by 3 cm surgical specimen obtained from a cortical-subcortical area of the de right occipital lobe showed a chronic granulomatous inflammatory process with a Spirometras pp larva. The patient was born and lived several years at a rural area of Tarija (Bolivia). This appears to represent the first reported case of this parasitic infection localized to the brain of a child in Argentina.

Neurological involvement in visceral leishmaniasis: case report / Envolvimento neurológico na leishmaniose visceral: relato de caso

Visceral leishmaniasis is a severe and potentially fatal vector-borne disease. The most typical symptoms are fever, hepatosplenomegaly, weight loss, bleeding and bacterial infections. Neurological changes are rarely reported. This paper describes a child who presented with neurological signs as the first symptoms of leishmaniasis; tone was diminished and tremors in the extremities were observed. A diagnosis of visceral leishmaniasis was confirmed by parasite detection in the bone marrow. Symptoms were reversed by specific treatment. The nature of a possible mechanism of neurological involvement in visceral leishmaniasis remains unexplained.

A leishmaniose visceral é uma doença severa e potencialmente fatal transmitida pela picada de flebótomos infectados pelo parasita. Os sintomas mais comuns incluem febre, hepatoesplenomegalia, perda de peso, sangramentos e infecções bacterianas. Alterações neurológicas têm sido raramente descritas nesses pacientes. Descrevemos aqui o caso de uma criança que desenvolveu um quadro de infecção pela Leishmania, tendo como principal sintoma tremor de extremidades. O diagnóstico da doença foi confirmado pela demonstração do parasita no aspirado de medula. Os sintomas foram revertidos pelo tratamento específico. A natureza do possível mecanismo do envolvimento neurológico na leishmaniose visceral permanece duvidoso.

A serological study of cysticercosis in patients with HIV / Estudo sorológico da cisticercose em pacientes com HIV

Neurocysticercosis (NCC) has attained the importance of one of the most common cause of focal brain lesions in patients infected with HIV (human immunodeficiency virus). Adequate data regarding the rate of this co-infection is lacking. Therefore, the present study was carried out to determine the prevalence of cysticercosis among HIV patients residing in Puducherry or its neighboring districts of Tamil Nadu State, India. A total of one hundred blood samples were collected from HIV seropositive cases visiting JIPMER hospital, Puducherry, between June 2007 and May 2008. Enzyme immunotransfer blot (EITB) and enzyme linked immunosorbent assay (ELISA) were used to demonstrate anti- T. solium larval stage antibodies and Co-agglutination (Co-A) test was used to detect T. solium larval stage antigens in sera. Two HIV seropositive cases were found positive for anti-T. solium larval stage antibody by EITB and four were positive by ELISA. Only one sample was positive by both EITB and ELISA. No serum sample was found positive for T. solium larval stage antigen by Co-A test. The overall seropositivity detected by all the methods was 5 percent in this study group. The accurate clinical diagnosis of NCC in HIV is difficult due to deranged immunological parameters in the HIV infected patients. The results of this study provides important data on the prevalence of cysticercosis in HIV positive patients in Puducherry and neighboring areas which was previously unknown. This study will also increase awareness among physicians and public health agencies about T. solium cysticercosis in the selected group.

Neurocisticercose (NCC) tem alcançado a importância de uma das mais comuns causas de lesões focais no cérebro em pacientes infectados pelo HIV (vírus da imunodeficiência adquirida). Dados adequados relativos à frequencia desta co-infecção estão faltando. Portanto, o presente estudo foi realizado para determinar a prevalência da cisticercose entre pacientes com HIV residindo em Puducherry ou distritos vizinhos do Estado de Tamil Nadu, India. Um total de cem amostras foram coletadas de casos soropositivos do Hospital JIPMER, Puducherry, entre junho de 2007 e maio de 2008. "Enzyme immunotransfer blot" (EITB) e ELISA foram utilizados para demonstrar anticorpos contra a fase larval do T. solium. Testes de co-aglutinação (Co-a) foram usados para demonstrar antígenos da fase larval do T. solium no soro. Dois casos HIV soropositivos foram positivos para anticorpos contra a fase larval do T. solium por EITB e quatro foram positivos por ELISA. Somente uma amostra foi positiva por ambos EITB e ELISA. Nenhuma amostra de soro foi positiva para antígeno da fase larval do T. solium pelo teste Co-a. A soropositividade total detectada por todos os métodos foi 5 por cento neste grupo de estudo. O diagnóstico clínico exato de NCC em HIV é difícil devido aos desordenados parâmetros imunológicos nos pacientes infectados pelo HIV. Os resultados deste estudo fornecem dados importantes sobre a prevalência da cisticercose em pacientes HIV positivos em Puducherry e áreas vizinhas que eram previamente desconhecidos. Este estudo também aumentará a atenção dos médicos e agências de saúde pública sobre a cisticercose por T. solium em grupo selecionado.

Cerebral schistosomiasis caused by Schistosoma mansoni: a case report with clinical analysis

Central nervous system involvement arising from schistosomiasis is uncommon. It may be produced most frequently by Schistosoma japonicum infection, but reports of S. mansoni presenting as an intracerebral mass lesion are particularly rare. The authors describe the case of a 35-year-old woman with a 3-month history of partial epileptic seizures and headaches. She immigrated to Egypt 4 years ago and had worked in Iraq for 2 years after the immigration. The patient's general physical and neurological examinations were unremarkable. Magnetic resonance [MR] imaging revealed an enhancing lesion with surrounding edema and mild mass effect in the left frontal lobe. A stereotactic brain biopsy demonstrated intraparenchymal granulomas surrounding S. mansoni eggs. S. mansoni was identified by stool examination. Prednisone [1 mg/kg per day for 1 week, with gradual withdrawal during the following 3 weeks] and praziquantel [2 doses at 20 mg/kg per day] therapy was initiated. The patient's symptoms resolved following medical treatment and the follow-up MR imaging yielded normal findings. This case is the rare imported case of cerebral schistosomiasis in China and the neuroschistosomiasis should be considered as the patient lived in a region in which this disease is endemic

Hydatid cysts of the brain

Brain involvement with hydatid disease occurs in 1-2% of all Echinococcus granulosus infections. Cerebral hydatid cysts are usually supratentorial, whereas infratentorial lesions are quite rare. Objective of the study was to determine the clinical presentation and surgical outcome of cranial hydatidosis. This retrospective study was performed in the department of neurosurgery LRH Peshawar from December 2000 to Oct 2007. Twenty one cases with intracranial hydatidosis were operated. The patients were either admitted through OPD or referred from other units. CT and/or MRI were the imaging modalities to reach the diagnosis in addition to serological and haematological tests. Surgery was the only treatment option used. Pericystic hydraulic method was the technique used for the excision of the hydatid cyst of brain. There were 9 males and 12 females with male to female ratio of 1:1.3. All patients belonged to paediatric age group with age range of 3-14 years and mean age of 7.42 +/- 3.2 years. Headache, vomiting, papilloedema were present in all the patients while seizures were the present in 16 patients. The lesion was removed surgically by adopting pericystic hydraulic method during craniotomy in all cases. There was no intra-operative morbidity except that the cyst ruptured in one case. No postoperative complications were noted and there was no mortality. Hydatid cyst of the brain presents clinically as intracranial space occupying lesion and is more common in children. Surgery is the treatment option with affordable morbidity and low mortality

Large primary cerebral hydatid cysts in children

Hydatid cyst disease in childhood is still a serious health problem in the rural areas of Turkey and other places where the parasite is endemic. The brain involvement rate varies from 1-2% in hydatid disease. Especially in children, hydatid cysts can grow to enormous sizes, and the cases can remain neurologically intact. In this report, a 7-year-old boy, a 15-year-old girl, and a 10-year-old girl, in whom large primary brain hydatid cysts were diagnosed radiologically and treated surgically, are presented. Severe headache in childhood should be taken into consideration carefully in countries where hydatid disease is seen

Neurocysticercosis in pregnancy

Neurocysticercosis is a common cause of adult onset epilepsy. Neurocysticercosis in pregnancy can present with convulsions and may be difficult to differentiate from a pregnancy related disorder. We present a case of neurocysticercosis diagnosed by magnetic resonance imaging

Cerebral hydatid cyst: 31 cases

Hydatid cyst is a pathology observed in developing countries; where it is a serious public health problem. Cerebral localisations are rare and the disease is primarily revealed by cranial hypertension signs, focal deficits, seizures and mental disturbances. The diagnosis is based on cerebral computerised tomography scan. The treatment is surgical with enucleation of the intact cyst. The authors report 31 cases of cerebral hydatid cyst operated during the period 1984 to 2001

Unusual presentation of echinococcal cysts

We report a case of echinococcal disease affecting the brain and the kidney. The case is unusual because of multiplicity of the intracerebral lesion and sparing of the liver and lungs. The intracerebral lesion was presented with epileptic convulsions. This was successfully treated surgically. Subsequently renal echinococcal cysts were identified. These were treated by partial nephrectomy due to the location of the cysts. The patient is disease free at 8 years

Neurocysticercosis in Kuwait: Computerized tomography and magnetic resonance imaging findings

To study the computerized tomographic [CT] and Magnetic Resonance Imaging [MRI] findings in seven Kuwaiti patients with neurocysticercosis. Material and The study population composed of seven Kuwaiti patients aged 3-44 years presented with seizures. The CT and MR imaging findings suggested neurocysticercosis. Serology [n = 2], histology [n = 2] and p resence of scolex on neuroimaging studies [n = 3], in addition, close contact with a carrier of neurocysticercosis further confirmed the diagnosis. CT and MRI depicted all lesions successfully. The lesions involved the brain parenchyma. There was no involvement of the cerebral ventricles, cisterns or brain stem. All patients, except one, had only one lesion and all were in the colloid vesicular stage. No calcification was noted. Neurocysticercosis is increasingly diagnosed in Kuwait. CT and MRI play an important role in the diagnosis of neurocysticercosis. Ring enhancing lesion with adjacent white matter edema was the dominant neuroimaging finding in our study. Neurocysticercosis should be an important differential diagnosis among Kuwaiti patients who have CT or MRI brain study showing ring-enhancing lesions

Neurocisticercosis en fase granulomatosa: presentación de un caso / A case report of glanulomatous-phase neurocysticercosis
