Dengue hemorrhagic fever, Axial FLAIR image ( ) shows symmetrical hyperintense signal in bilateral frontoparietal white matter and right frontal gray matter. Axial SWI images ( ) show multiple macrobleeds and microbleeds in bilateral frontal and left parietal posterior temporal lobe. (Diagnosis was confirmed by positive dengue serology).

Intraparenchymal brain hemorrhage is not uncommon and results from a wide variety of causes ranging from trauma to tumor. Many a time, it is not possible to determine the exact cause of non-traumatic hemorrhage on conventional magnetic resonance imaging (MRI). Susceptibility-weighted imaging (SWI) is a high-resolution (3D) gradient-echo sequence. I...
