BACKGROUND
An intracranial neurenteric cyst (NC) is a rare congenital benign lesion that usually has a well-demarcated cystic appearance without contrast enhancement on magnetic resonance imaging (MRI). In particular, an intracranial NC with an enhanced mural nodule is extremely rare.

Fargesin is commonly used in the treatment of allergic rhinitis, inflammation, sinusitis and headache.The aim of the study is to investigate a new function of fargesin against melanin production and its underlying molecular Dynamic thalamic regulation of sensory signals allows the cortex to adjust better to rapidly changing behavioral, physiological, and environmental demands. To fulfill this role, thalamic neurons must themselves be subjected to constantly changing modulatory inputs that originate in multiple
It was one of the great pleasures to have fulfilled my long-held dream in 1986, newly opened the Kitasato University East Hospital (KUEH). In 1965, I served at chronic ward of Baltimore City Hospitals as a resident of neurology, where most of the patients were relaxed and enjoyed their hospital
We report a 74-year-old woman and a 50-year-old woman with similar histories of headache and visual disturbance who were found to have adamantinomatous craniopharyngiomas which contained melanin pigment. This finding was confirmed by the Masson Fontana method and ultrastructural studies. These are
A 54-year-old male presented with the history of headache and vomiting. MRI of the head showed right posterior temporal mass which was surgically excised. Histopathological examination revealed features of glioblastoma with pigmented cells. The pigment was demonstrated to be melanin which was
BACKGROUND
Meningeal melanoma is a rare tumor of the central nervous system, whose amelanotic variant is the so-called 'amelanotic meningeal melanoma (AMM)'. AMM does not produce melanin and therefore does not exhibit typical short-T1 and short-T2 signal on MRI, and thus can be easily misdiagnosed
We conducted a retrospective study of 58 cases of cryptococcosis (1986-2008) with urine test positive for Cryptococcus sp, in Mycology Laboratory, Santa Casa-Hospital Complex, Porto Alegre, RS, Brazil. The diagnosis of cryptococcuria was based on microscopic examination and culture of urinary
Phaeohyphomycosis is a term used to define infections caused by darkly pigmented fungi with septate hyphae which contain melanin in their cell walls. Although fungi rarely cause central nervous system (CNS) infections, the incidence of CNS infections caused by melanin-containing fungi has been
Meningeal melanocytoma is a primary melanocytic neoplasm with certain MR and immunohistochemical characteristics worthy to note. In a 38-year-old man with a complaint of headache for a couple of years and recently added nausea, vomiting, diplopia, progressive visual blurring and hearing loss,
Medulloblastoma is an embryonal neuroepithelial tumor of the cerebellum and is the most common malignant central nervous system tumor in children. Different histological variants and patterns have been described. The classic variant represents the majority of cases. This report describes a rare case
Neuro cutaneous melanocytosis (NCM) is a non-familial, congenital disorder characterized by multiple congenital nevi and brain or leptomeningeal abnormal melanin deposits. Here, we present an adult onset NCM. A 17-year-old boy presented with headache and double vision for 1 month. Magnetic resonance
BACKGROUND
Case report of congenital grouped albinotic spots.
METHODS
A 24-year-old woman was referred for frontal headache related to +1.50 hypermetropia. Visual acuity was 20/20 in both eyes. During routine examination, fundus examination revealed multiple, irregular white spots involving the
Central neurocytoma is a low-grade neuronal neoplasm that occurs most often within the lateral ventricles. We report the case of a 60-year-old woman who presented with gait problems, headache and memory loss. Preoperative evaluation demonstrated a heterogeneous, hypervascular and partially cystic
Intracranial schwannomas account for 8% of all intracranial tumors, out of which 90% are acoustic schwannomas. Other rare varieties include trigeminal melanotic schwannomas that account for 0.2% of all intracranial tumors. Melanotic schwannomas are intracranial tumors that are heavily pigmented due
