A 56-year-old woman was referred to our hospital for the further evaluation of drug-refractory heart failure with a reduced ejection fraction. A family history interview revealed that men in her family had died of Duchenne muscular dystrophy (DMD), whereas she had no skeletal muscle disorder. ⋯ X-linked dilated cardiomyopathy (XLDCM).

The early diagnosis of cerebral venous thrombosis in the emergency department is challenging. A 70-year-old man presented to the emergency department after falling with new-onset convulsions. ⋯ Brain unenhanced CT on day 2 revealed increased density in the anterior superior sagittal sinus (SSS), namely 'dense inverted triangle sign.' Brain magnetic resonance venography showed a filling defect in the anterior SSS. When interpreting unenhanced brain CT findings in the setting of acute convulsions or cortical stroke, including SAH, cerebral sinus abnormalities near stroke foci should be evaluated carefully.
