Abstract Urethral melanomas are a rare subtype of noncutaneous melanomas. The disease has tendency to have skip lesions and early metastases as compared with cutaneous role fluorine-18 fluorodeoxyglucose (18F-FDG) positron emission tomography computed (PET-CT) is well established in cases recommended by the National Comprehensive Cancer Network (NCCN) for stage IIB IV cancer. There no guideline...

Thallium-201 (201Tl) scintigraphy is one of the imaging methods used in the detection of various tumors including brain metastasis. We evaluated a patient with meningeal carcinomatosis from breast cancer by using 201Tl single-photon emission computed tomography (SPECT). Meningeal spread of a tumor was noted on enhanced CT. SPECT revealed tumor localization in meningeal carcinomatosis. These res...

Introduction Cortical spreading depression (CSD) is believed to promote migraine headache by enhancing the activity and mechanosensitivity of trigeminal intracranial meningeal afferents. One putative mechanism underlying this afferent response involves an acute excitation of meningeal afferents by cortical efflux of K+ and the ensuing antidromic release of proinflammatory sensory neuropeptides,...

BACKGROUND Timely diagnosis of meningeal carcinomatosis is often difficult even with the assistant of magnetic resonance imaging examination, cerebrospinal fluid analysis, or both. To the best of our knowledge, gadobutrol-enhanced MRI has not been reported in the diagnosis of meningeal carcinomatosis. Here we present two cases where meningeal carcinomatosis was identified on gadobutrol-enhanced...

Background Dynamic optical coherence tomography (D-OCT) allows in vivo visualization of blood vessels the skin and malignant tumours. Vessel patterns melanoma may be associated with tumour stage. Objective The aim this study was to describe vessel melanomas correlate them Methods One hundred fifty-nine were assessed a multicentre study. Every imaged using D-OCT prior surgery histologic evaluati...
