Transcallosal Removal of a Choroid Plexus Tumor From the Lateral Ventricle in a Dog. Case Report

et al. 2020

A 6-years-old female Staffordshire terrier was referred for periodic generalized seizures and asymmetric visual deficits. Magnetic resonance imaging revealed a 23.2 × 19.3 × 23.0 mm soft tissue mass within the right lateral ventricle and consequential dilatation of the lateral ventricles. Surgically, an interhemispheric approach was performed next to the marginal gyrus after a right parieto-parasagittal craniotomy, and a large choroid plexus tumor was transcallosally removed. After 3 days, the dog was discharged to home, and supportive treatment was continued. Histology revealed a choroid plexus papilloma, which was also confirmed by immunohistochemistry. One month after surgery, a control MRI showed that the ventricles were still dilated, but there was no sign of recurrent tumor. The dog had two additional seizures at home during the month following the intervention and one more grand mal episode was observed 4 months after the surgery. Nine months after the surgery, the dog showed no seizure activity, but her vision had not yet returned.

ResumoO presente trabalho relatou um caso clínico de meningioma na tenda cerebelar, evidenciando seus aspectos clínicos, imaginológicos e histopatológicos, com o intuito de ampliar o conhecimento do médico generalista, favorecendo o diagnóstico e o tratamento da doença. O caso relatado foi de um paciente do sexo masculino na sétima década de vida, que permaneceu com a lesão durante 4 meses após apresentar os primeiros sinais e sintomas. O diagnóstico definitivo foi realizado com auxílio de ressonância magnética e, imediatamente, a opção terapêutica instituída foi a ressecção completa da lesão. Mediante tal relato, pode-se concluir que a investigação clínica é essencial mesmo em pacientes fora do grupo de maior incidência da lesão, sendo que o conhecimento das principais características da doença facilita o diagnóstico precoce e, consequentemente, antecipa o tratamento adequado, resultando no melhor prognóstico do paciente.

AbstractThe present study reported a clinical case of meningioma in the cerebellar tent, evidencing its clinical, imaging and histopathological aspects, in order to broaden the knowledge of the general practitioner, favoring the diagnosis and treatment of the disease. The case reported was of a male patient in the seventh decade of life, who remained with the lesion for 4 months after presenting the first signs and symptoms. The definitive diagnosis was made with the aid of magnetic resonance imaging, and immediately, the therapeutic option instituted was the complete resection of the lesion. By means of such a report, it can be concluded that clinical investigation is essential even in patients outside the group with a higher incidence of the injury, and knowledge of the main characteristics of the disease facilitates early diagnosis and, consequently, anticipates appropriate treatment, resulting in better prognosis for patients.

“…The symptoms of intraventricular ganglioglioma are caused by obstruction of CSF flow and hydrocephalus, headache and visual impairment being common 8 . According to various reports 6 - 11 , intraventricular gangliogliomas can originate in the lateral ventricles, in the third ventricle, and fourth ventricles-some even originating in the choroid plexus-and should always be included in the differential diagnosis of intraventricular lesions.…”
