RESUMO
Choroid plexus papilloma (CPP) is a rare intraventricular tumor. The common locations of the tumor vary based on the age of the patient. It usually occurs in the supratentorial region in children, however in adult patients, these tumors commonly present in the infratentorial region. We are presenting a rare case of a pediatric patient with a two month history of decreased activity and loss of interest in his surroundings and gait imbalance. He underwent a suboccipital craniotomy and excision of a CPP in the fourth ventricle. In conclusion, CCP should be considered as part of the differential diagnosis of intracranial tumors when the clinical presentation and investigations are suggestive regardless of the location to avoid misdiagnosing it when it occurs in an uncommon location.
RESUMO
Acute subdural hemorrhage (SDH) is a rare complication that can occur after a spontaneous intracranial aneurysmal rupture. It is commonly associated with a subarachnoid and/or an intracerebral hemorrhage but rarely occurs as an SDH alone. A 52-year-old female presented to our institution with a severe headache and third cranial nerve palsy. A computed tomography (CT) scan revealed acute left SDH, without a subarachnoid hemorrhage (SAH), and a computed tomography angiogram (CTA) and cerebral angiography demonstrated the presence of a left supraclinoid aneurysm pointing towards the cavernous sinus. Endovascular occlusion of the aneurysm was performed using a flow diverter. A follow-up CT scan revealed a resolved SDH. In similar situations, vascular imaging, such as CTA and cerebral angiography, is required to assess the cerebral vasculature. This case report describes a patient presenting with the sudden onset of a severe headache associated with a cranial nerve palsy and a brain CT scan showing an acute SDH in the absence of trauma or an anticoagulation history. The treating physician should be highly vigilant of the possibility of a ruptured intracranial aneurysm as the underlying SDH etiology.
RESUMO
Carpal tunnel syndrome (CTS) is one of the most common peripheral nerve diseases. It is managed medically and if not, resolved by surgical procedure. Decompression of the carpal tunnel is considered the definitive treatment. There are multiple complications after this procedure, which can be classified into three categories: (I) persistent, (II) recurrent, or (III) new symptoms, and ulnar nerve palsy after decompression of the carpal tunnel is a rare complication. In this study, we present a case of carpal tunnel decompression, which was complicated by ulnar nerve palsy, which exacerbated a pre-existing chronic ulnar nerve injury. We also explore the possible causes that may have led to this outcome.
