ABSTRACT
Gallbladder duplication results from a rare abnormality of embriogenesis and is twice as common in women as in men. The signs and symptoms of double gallbladder cholecystitis are the same as those of single gallbladder cholecystitis: strong pain in the epigastric region and right hypochondrium, which may irradiate to the back and be accompanied by nausea and/or vomiting, Murphy positive sign, and pain on palpation of these regions; plastron may also be present. For this reason, many cases are still diagnosed intraoperatively, making surgery difficult and increasing the possibility of biliary tract injury. We report the case of a female patient with epigastric and dorsal pain for 4 days, which worsened with the ingestion of salty and fatty foods and was accompanied by nausea and vomiting. Physical examination showed a positive Murphy sign. A complete abdominal ultrasound examination showed gallbladder duplication, both lithiasic. Magnetic resonance cholangiography confirmed the duplication of the gallbladder and cystic ducts, with a single main biliary tract and acute lithiasic cholecystitis in both gallbladders. A laparoscopic cholecystectomy of both vesicles was performed without complications, and the patient was discharged 3 days after the procedure. (AU)

Atypical rhabdoid teratoid tumors (ARTTs) are rare embryonic tumors, usually localized in the posterior fossa and diagnosed in children under 3 years-old. The treatment includes surgical resection, radio and chemotherapy, and the prognostic is unfavorable, with an average median survival of 1 year. We present the case of a 3-year-old patient, with history of headache and vomiting, followed by absence seizures, temporal automatism, syncope accompanied by sialorrhea and sphincteric loss succeeded by a postictal period. Surgical excision was performed and the anatomopathological study confirmed ARTT. The ARTTs are embryonic tumors, a category in which medulloblastoma and primitive neuroectodermal tumors (PNETs) represent the most common central nervous system (CNS) malignancies in childhood.
Tumores teratóides rabdóides atípicos (TTRA) são tumores embrionários raros, geralmente localizados na fossa posterior e diagnosticados em crianças com menos de 3 anos de idade. O tratamento inclui ressecção cirúrgica, radio e quimioterapia. Contudo, o prognóstico é desfavorável, com uma sobrevida média de 1 ano. Apresentamos o caso de um paciente de 3 anos de idade, com quadro de cefaléia e vômitos, companhados por automatismo temporal e perda de consciência, seguidos por período pós-ictal. A ressonância nuclear magnética (RNM) do encéfalo evidenciou lesão frontal compatível com tumor intra-axial, efeito de massa local e invasão do corpo caloso. Foi realizada excisão cirúrgica, e o estudo anatômico-patológico confirmou TTRA. Os TTRA são tumores embrionários, categoria na qual o meduloblastoma e os tumores neuroectodermais primitivos representam as malignidades mais comuns no sistema nervoso central de crianças.
