  • Neurolymphomatosis as primary presentation of extra-nodal NK/T-cell lymphoma, nasal type
    Publication . Silva, MI; Santos, P; Viegas, D; Miranda, M; Montes, V; Pita, F; Carmona, C
    Neurolymphomatosis (NL) describes an infiltration of cranial and peripheral nerves by lymphoma cells, most frequently in non-Hodgkin B-cell lymphoma. This clinical entity is rare and poses a challenging diagnosis. We describe a case of a 64-year-old female patient with NL associated with extra-nodal NK/T-cell lymphoma (ENKTL), nasal type, presenting as a painful progressive mononeuropathy multiplex with an oral cavity lesion. ENKTL is usually associated with Epstein-Barr virus (EBV) infection and rarely affects the central and peripheral nervous system. Lumbar puncture, magnetic resonance imaging (MRI), nerve biopsy, and 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) help to establish the diagnosis. Thereby, NL should be considered in the differential diagnosis of painful progressive multiple neuropathies, even in patients without previous history of cancer.

  • No reason to smile: giant internal carotid artery aneurysm
    Publication . Miranda, M; Marques, D; Montes, V; Pita, F
    Giant cerebral aneurysms account for approximately 5% of all intracranial aneurysms, affecting morecommonly women in the 5th to 7th decade. When untreated, giant intracranial aneurysms face a poor prognosis withan estimated 2-year mortality of 68%. We present the case of an 82-year-old woman admitted at the emergencydepartment due to two focal to bilateral tonic-clonic seizures with a giant aneurysm of the supraclinoid segment ofthe right internal carotid artery on the CT scan. We discuss different management approaches for giant internalcarotid artery aneurysms, including direct surgical clipping, reconstructive endovascular procedures (coiling, balloon-/stent-assisted coiling, and flow diversion), deconstructive endovascular techniques (parent artery occlusion), andconservative management.
