ABSTRACT CONTEXT: Central nervous system (CNS) infectious diseases have high prevalence in developing countries and their proper diagnosis and treatment are very important for public health planning. Cryptococcus neoformans is a fungus that may cause several CNS manifestations, especially in immunocompromised patients. Cryptococcal meningitis is the most common type of involvement. Mass-effect lesions are uncommon: they are described as cryptococcomas and their prevalence is even lower among immunocompetent patients. The aim here was to report an extremely rare case of cryptococcoma causing a mass effect and mimicking a brain tumor in an immunocompetent patient. The literature on CNS cryptococcal infections was reviewed with emphasis on cryptococcomas. Clinical, surgical and radiological data on a female patient with this rare presentation of cryptococcoma mimicking a brain tumor are described. Case Report: A 54-year-old female patient presented to the emergency department with a rapid-onset progressive history of confusion and completely dependency for basic activities. Neuroimaging showed a left occipital lesion and neurosurgical treatment was proposed. From histopathological evaluation, a diagnosis of cryptococcoma was established. She received clinical support with antifungals, but despite optimal clinical treatment, her condition evolved to death. CONCLUSIONS: Cryptococcal infections have several forms of presentation and, in immunocompetent patients, their manifestation may be even more different. Cryptococcoma is an extremely rare presentation in which proper surgical and clinical treatment should be instituted as quickly as possible, but even so, there is a high mortality rate.

O aumento da sobrevivência do paciente oncológico decorrente da melhoria e do avanço das modalidades terapêuticas promove progressivo aumento da prevalência das neoplasias metastáticas da coluna vertebral, tornando o seu conhecimento condição sine qua non para os profissionais da área de saúde. As metástases na coluna vertebral são usualmente procedentes de neoplasia maligna da mama, pulmão e próstata, o gênero masculino é o mais acometido e a dor é o sintoma inicial em mais de 90% dos pacientes. Estima-se que 30-90% dos pacientes com câncer em estágio terminal apresentem metástase em algum segmento da coluna vertebral. A alta prevalência das neoplasias malignas e a significativa experiência dos autores no tratamento das metástases na coluna vertebral motivaram uma atualização do tema. Acreditamos que a padronização da conduta e o conhecimento pormenorizado dos principais aspectos da doença, podem promover a melhor opção terapêutica. O presente estudo visa à revisão e descrição didática dos principais aspectos relacionados à fisiopatologia, diagnóstico e tratamento desta entidade.

The increased survival of cancer patients due to the improvement and advancement of therapeutic modalities has promoted progressive increase in the prevalence of metastatic tumors of the spine, making it important for healthcare professionals to acquire knowledge in the field. Spinal column metastases are usually secondary to malignant neoplasm of the breast, lung and prostate, male gender being the most often affected and pain being the initial symptom in 90% of patients. It is estimated that 30-90% of terminally ill patients with cancer have metastases at some spinal column segment. Clinical history, physical and neurological assessments are critical to determine the degree and extent of the lesion, and therefore choose the appropriate imaging method to be requested. This study aims to perform a review and didactic description of the main aspects related to the physiopathology, diagnosis and treatment of this disease.

Os meningeomas são neoplasias derivadas das células aracnóideas, sendo sua origem ligada a alterações genéticas idiopáticas (deleção do braço longo do cromossomo 22), doenças predisponentes à sua formação e indução por radioterapia. Relata-se o caso de um homem de 50 anos com meningeoma pós-radioterapia diagnosticado 20 anos após o tratamento de um oligodendroglioma. Os critérios que suportam o diagnóstico de meningeoma induzido por radioterapia são discutidos, assim como é revisada a literatura pertinente ao assunto.

Meningiomas are neoplasms derived from arachnoid cells with their origin linked to idiopathic genetic abnormalities (delection of the long arm of chromosome 22), predisposing diseases and radiotherapy induction. We report the case of a 50 years-old man radiation-induced meningioma 20 years after the diagnosis, surgical and radiation treatment of an oligodendroglioma. The supporting diagnostic criteria of radiation-induced meningiomas are discussed and the pertinent literature of the theme is revised.
