Intraneural pseudocyst (so-called ganglion) in an unusual retroperitoneal periadnexal location?

A case of an unusual unilocular cystic lesion of diameter 7 cm located retroperitoneally in the pelvis in close connection to the right adnexa of a 61 year-old woman is presented. Macroscopically, the lesion had a smooth outer and inner surface and was filled with translucent fluid. Histological examination revealed a fibrous and hyalinized wall which lacked a specific lining. Numerous nerve bundles in the cyst wall constituted the most conspicuous element of its histology possibly with some contribution of perineurial and/or mesothelial components. The morphology and immunohistochemistry speak for an intraneural pseudocyst sometimes called intraneural ganglion cyst which is rare in this location

Endarterectomia de carótida sob anestesia local: evolução de 104 pacientes Carotid endarterectomy under regional anesthesia: follow-up of 104 patients

A estenose carotídea cervical é uma das causas mais freqüentes de acidente vascular cerebral isquêmico. A endarterectomia de carótida é um tratamento eficaz para lesões estenóticas moderadas e graves, tanto sintomáticas quanto assintom��ticas. A endarterectomia realizada sob anestesia local permite a monitorização neurológica do paciente durante o ato cirúrgico. O objetivo deste trabalho foi avaliar as complicações cirúrgicas e acompanhar a evolução dos pacientes submetidos a endarterectomia sob anestesia local em nossa instituição, comparando os resultados com outras publicações. 104 pacientes foram submetidos a 110 procedimentos no período de abril de 1996 a maio de 2002. 64 pacientes eram sintomáticos (61,54%) e 40 assintomáticos (38,46%). Todos possuíam grau de estenose carotídea igual ou superior a 70%. Os pacientes foram avaliados retrospectivamente. O tempo de evolução variou de um a 72 meses (média: 29,5). Três pacientes apresentaram hematoma cervical necessitando drenagem cirúrgica. Dois pacientes (1,92%) tiveram acidente vascular cerebral do mesmo lado da endarterectomia no pós-operatório e outros dois durante o seguimento. Dois pacientes faleceram em decorrência da cirurgia (1,92%). Os resultados desta série, comparados com a literatura, permitem concluir que a endarterectomia é uma forma segura de tratamento para as estenoses carotídeas moderadas e graves.<br>Cervical carotid stenosis is one of the main causes of ischemic stroke. Carotid endarterectomy is a safe procedure for treatment of moderate and severe symptomatic and asymptomatic carotid stenosis. Regional anesthesia allows neurological evaluation of the patient during the surgery. We reviewed the results of 104 patients operated on at our institution under regional anesthesia during the period of April 1996 and May 2002. 64 patients were symptomatic (61.54%) and 40 asymptomatic (38.46%). All patients had carotid stenosis over 70%. The patients were followed from one to 72 months (Mean: 29.5). Three patients had cervical hematoma, that required surgical drainage. Two patients had minor stroke at the same side of the endarterectomy at the post-operative period and another two during the follow-up (1.92%). Two patients died due to complications related to the surgery (1.92%). Our results, compared with the literature, show that endarterectomy is a safe procedure to treat moderate or severe carotid artery stenosis
