Double Pituitary Incidentaloma in a Young Woman With Sinusitis-Related Headache

Intracranial Complications of Sinogenic and Otogenic Infections in Children: an...

Background: COVID-19 pandemic is thought to have changed the epidemiology of some pediatric neurosurgical disease: among them are the intracranial complications of sinusitis and otitis (ICSO). According to some studies on a limited number of cases, both streptococci-related sinusitis and ICSO would have increased immediately after the pandemic, although the reason is not clear yet (seasonal changes versus pande...

Cerebrospinal Fluid Hypotension Following Fall in a Child: Case Report

CSF hypotension arises in the context of a leak of CSF which causes negative intracranial pressure. Sacral fractures result from high-energy trauma which are frequently underdiagnosed. A ten-year-old boy presented with hip pain, after a fall. He mobilized both lower limbs, reported no leg pain, irradiation nor lack of sphincter control. The neurological examination was normal. When asked to stand, he began bipa...

Periodontoid Pseudotumor in Tuberous Sclerosis Associated With Neck Diffuse Lip...

Tuberous sclerosis (TS) is a genetic multisystem disorder associated with the development of benign tumors in many organs. Diffuse lipomatosis, which represents the overgrowth of fatty tissue in one part of the body, is a very rare finding reported in patients with tuberous sclerosis. We describe the case of a patient with diffuse lipomatosis in the right scapular, posterior cervical and perivertebral regions, ...

A T1-Hypointense Intracranial Dermoid Cyst

Langerhans Cell Histiocytosis in the Occipital Condyle: A Case Study and a Brie...

We present a case study of a 5-year-old patient, who presented with left-sided torticollis. Due to persistence of problems, a CT and an MRI were made showing a single osteolytic lesion centred on right occipital condyle. After an open biopsy, histology confirmed it to be Langerhans cell histiocytosis (LCH). Torticollis or restricted range of motion is a presenting feature in 76% of children with LCH with cervic...

BRAF V600E Mutation and 9p21: CDKN2A/B and MTAP Co-Deletions - Markers in the C...

Genetic alterations in pediatric primary brain tumors can be used as diagnostic and prognostic markers and are the basis for the development of new target therapies that, ideally, would be associated with lower mortality and morbidity. This study evaluates the incidence and interplay of the presence of BRAF V600E mutation and chromosomal 9p21 deletions in a series of 100 pediatric gliomas, aiming to determine t...

Extensive Inner Ear and Facial Canal Lipoma - a Case Report

Inner ear lipomas are rare benign congenital lesions, most frequently presenting at the internal auditory canal and labirynth. Lipomas of the facial nerve are even less frequent. We present a case of a lipoma involving all internal ear structures and VII nerve canal and extending intracranially and extracranially, presenting with facial palsy and ipsilateral hearing loss. To our knowledge this is the most exten...

Cordoma do Clivus: Abordagem Endocópica Endonasal Transesfenoidal

Os cordomas da base do crânio são tumores raros, localmente destrutivos, que constituem um desafio cirúrgico pela proximidade a estruturas neurovasculares vitais e ao elevado potencial de recidiva. Os autores descrevem o caso de uma mulher de 45 anos, com quadro de cefaleias, anisocória e diplopia, com cinco meses de evolução, cujos exames complementares de diagnóstico revelaram uma volumosa lesão expansiva dos...
