Cryptococcosis is a relatively common mycotic infection of the CNS caused by a ubiquitous saprophytic fungus. We present an unusual case of CNS cryptococcosis in an immunocompetent patient. Florid choroid plexitis resulted in the formation of intraventricular enhancing mass lesions that filled the ventricles and were hyperintense to associated periventricular edema on T2-weighted MR images. We ...

Skin lesions are visual clinical manifestations of decompression sickness (DCS). Comprehensive knowledge of skin lesions would give simple but strong clinical evidence to help diagnose DCS. The aim of this study was to systematically depict skin lesions and explore their pathophysiological basis in a swine DCS model. Thirteen Bama swine underwent simulated diving in a hyperbaric animal chamber ...

The radiological abnormalities reported in CNS tuberculosis and their pathological correlates are discussed. Focal tuberculous involvement of the CNS without formation of tuberculoma is rare. The MR features in this case were also distinctly unusual for CNS tuberculosis. Therefore, histological confirmation of all lesions thought to be a low grade glioma is mandatory.

The complex interplay between hypernatremic osmotic disturbances and cerebral lesions is yet to be clarified. In this review, we discuss, on the basis of the reported data of hypernatremic CNS challenge in the adult population, the clinical and radiologic features of the condition. Our search captured 20 case studies and 1 case series with 30 patients in total who acquired acute hypernatremia d...

Balò's concentric sclerosis (BCS) is a rare primary demyelinating disease of central nervous system (CNS) and is considered to be a variant of multiple sclerosis (MS). It is characterized by a severe, rapidly evolving course with CNS lesions consisting of concentric rings of demyelination alternating with myelination in the white matter. We report a patient with BCS from mainland China diagnose...

BACKGROUND Although aneurysm formation accompanying parenchymal hemorrhage is one of devastating complications in the central nerves system (CNS), imaging studies of the brain are not routinely warranted in patients with infective endocarditis (IE). To assess the clinical importance for detecting silent lesions in the central nervous system, we investigated hypointense signal spots detected on ...

Our patient was worked up for mild developmental delay associated with focal scalp alopecia at age 6, and was diagnosed with encephalocraniocutaneous lipomatosis (also known as Haberland or Fishman syndrome), a rare neurocutaneous syndrome characterized by skin lesions (most commonly focal alopecia with or without underlying lipoma), ocular lesions, and CNS anomalies. CNS anomalies are usually ...

Neurofibromatosis type 1 (NF1) is the most common neurocutaneous disease. Main neurologic manifestations are represented by neoplasms such as optic gliomas, but epilepsy can occur by CNS lesions in less than 10%. Our patient was diagnosed, based on café-au-lait spots and axillary freckles. Her brain MRI did not show only multiple CNS lesions, like hamartomas, but also mesial temporal lesions. O...

When a central nervous system (CNS) lesion is found in patients with chronic lymphocytic leukemia (CLL), the diagnostic possibilities include CNS involvement of CLL, transformation to large B-cell lymphoma (Richter’s syndrome [RS]), or coincidental presence another tumorous non-tumorous disease. RS commonly occurs preexisting CLL other nodal/extra-nodal involvement, but it extremely rare find i...
