- From spinal ependymoma to superficial siderosis: a bottom to top cause of progressive neurological deteriorationPublication . Valente, Diana; Felix, Catarina; Nzwalo, Hipólito; Gil, InêsSuperficial siderosis (SS) is an infrequent condition characterized by hemosiderin deposition in the central nervous system, resulting from chronic subarachnoid hemorrhage, often linked to dural mater diseases. Through a case report of a 50-year-old male with severe sensorineural hearing loss and newly diagnosed epilepsy, we explore SS triggered by a spinal ependymoma, diagnosed via resonance magnetic imaging (MRI). This case highlights the necessity of comprehensive neuroaxis imaging to identify treatable etiologies. The complexity of SS, with its varied clinical presentations, necessitates early detection and a multidisciplinary treatment approach. Despite limited treatment options and the uncertain efficacy of therapies like deferiprone, early intervention is crucial for mitigating irreversible neurological damage and enhancing patient prognosis.
- Isolated vocal cord paresis as a presentation of acute ischemic strokePublication . Valente, Diana; Gil, Inês; Jacinto, Filipe; Freitas, Luís; Nzwalo, Hipólito; Felix, CatarinaStroke presenting with predominant laryngeal dysfunction manifestations is often part of a clinical constellation of neurological signs associated with acute medullar lesion [1]. Isolated laryngeal symptoms as a stroke presentation are extremely rare due to the intimal anatomical relation of swallowing-related structures with the ascending/descending tracts in the lateral medulla [2]. Herein we present a case with isolated vocal cord paresis as the sole manifestation of acute ischemic stroke.
