ABSTRACT This is a case report of a patient with tuberous sclerosis who has been followed since the age of 8 months. An ophthalmological examination revealed left eyelid ptosis and a lesion consistent with retinal astrocytoma. Imaging studies, including magnetic resonance imaging and computed tomography, demonstrated multiple abnormalities such as cortical-subcortical lesions, subependymal nodules, callosal dysgenesis, and probable renal cysts. The patient also presented with refractory epilepsy, developmental delay, and frequent seizures. Correlating the clinical and radiological findings with the […]

ABSTRACT Cavernous hemangiomas are benign malformations of vascular origin, generally well circumscribed and with slow growth. These lesions can be asymptomatic, being discovered unintentionally on imaging exams, or symptomatic, indicated mainly by the presence of proptosis, diplopia, and visual disturbances due to compression of the optic nerve. Preoperative evaluation is essential and makes the use of imaging exams essential for carrying out adequate planning, with computed tomography and magnetic resonance imaging being the first choices. Treatment can be conservative or […]

ABSTRACT Penetrating cranio-orbital injuries are uncommon events and represent a small percentage of cranioencephalic traumas. The clinical condition and surgical management were described by reviewing the patient’s electronic medical records. This case reports on a 37-year-old male patient who suffered penetrating trauma to the skull from the brake lever of his bicycle as a result of an accidental fall while cycling. Brought in by the SAMU, the patient had a Glasgow score of 15, a preserved left orbit, while the […]

ABSTRACT Traumatic chiasmal syndrome is one of the rare etiologies of chiasmal syndrome, characterized by optic chiasm injury following head trauma. The main visual defect associated is bitemporal hemianopia with macular splitting; however, it can present with a variety of other visual defects and neurologic signs. The authors report a case of complete bitemporal hemianopia after head trauma, with multiple frontal and skull base fractures and no other neurologic deficits, or hypothalamic-pituitary abnormality. Most cases of traumatic chiasmal syndrome are […]

Melanomas coroidais são os tumores malignos intra-oculares primários mais comuns em adultos. Eles tendem a ser mais malignos; devido à sua localização ser escondida por detrás da íris eles não podem ser detectados até se tornarem maiores. A estratégia terapêutica está relacionada com tamanho, extensão, número e localização dos padrões tumorais e de crescimento. O biomicroscopio ultra-sónico de alta frequência (BMU) fornece imagens transversais de alta resolução das lesões do segmento anterior. Lesões pós-equatoriais e de extensão intracraniana dos melanomas […]

A adrenoleucodistrofia ligada ao X (X-ALD) representa um grupo de doenças caracterizadas pelo acúmulo de ácidos graxos de cadeia muito longa (VLCFAs) nos tecidos. Suas manifestações clínicas costumam ser múltiplas. Alterações visuais podem estar presentes, contudo costumam surgir mais tardiamente na doença. Descrevemos aqui o caso de um menino de 9 anos com X-ALD, cujo primeiro sintoma foi perda visual, iniciada aos 8 anos de idade. A sua avaliação oftalmológica não revelou alterações. Pouco tempo depois, ele sofreu um traumatismo […]

Choroidal melanomas are the most common primary intraocular malignant tumor in adults. They tend to be more malignant; because of their location hidden behind the iris they can not be detected until they become larger. Therapeutic strategy is related by size, extension, number and location of tumor and growth patterns. High frequency ultrasound biomicroscopy (UBM) gives high resolution, cross-sectional images of the anterior segment lesions. Postequatorial lesions and intracranial extension of the melanomas are scanned by magnetic resonance imaging (MRI). […]

X-linked adrenoleukodystrophy (X-ALD) represents a group of diseases characterized by the accumulation of very long chain fattyacids (VLCFAs) in the tissues. Its clinical manifestations are usually manifold. Visual changes may be present, but they often appear later in the disease. We describe here the case of a 9-year-old boy with X-ALD, whose first symptom was visual loss, which began at 8 years of age. His ophthalmologic evaluation revealed no alterations. Shortly thereafter, he suffered a head injury. The magnetic resonance […]
