RESUMO
Neurofibromatosis type 2 (phacomatosis) is a rare inherited autosomal dominant condition defined by the development of numerous central neuronal tumors. In addition to classic intracranial schwannomas, intracranial and spinal meningiomas, and intramedullary ependymomas, it can be associated with a few cutaneous abnormalities. In this report, we discuss the case of a 21-year-old female who was examined for persistent headache with cutaneous masses and bilateral hearing loss. Magnetic resonance imaging of the cranium and the whole spine detected multiple meningiomas, intracranial, and intramedullary tumors.
RESUMO
Neuroblastomas commonly metastasize to the cranium and orbit, although other facial bones were less implicated. In this report we present a 3 years old child with metastatic neuroblastoma to the mandible that presented with swollen right jaw. The first assessment of the head with computed tomography revealed soft tissue mass with permeative lytic changes of the osseous structures centered on the right mandible, as well as osteo-meningitis metastases. These masses were proven to be metastatic lesions from intra-abdominal neuroblastoma of the right adrenal gland. Over the previous several years, only 29 cases of neuroblastoma metastasis to the mandible have been reported in the literature.
RESUMO
Hepatic metastases from carcinoid tumours are typically solid, hypervascular lesions on imaging. The cystic form, mimicking an abscess, is extremely rare. We report a case of a 48-year-old female presenting with a large hepatic mass that was diagnosed as a hepatic abscess, but the ultrasound-guided biopsy showed well-differentiated grade 1 neuroendocrine tumour. CT scan of chest, abdomen and pelvis was performed, looking for the primary tumour, it revealed an endobronchial mass of the right inferior lobe. Lung biopsy by rigid bronchoscopy was taken confirming the diagnosis of a typical carcinoid tumour.
