Vascular lesions: Hemangioma or venous malformation?

We present a case of a 62-year-old female who was incidentally found to have a venous malformation. Venous malformations are part of a larger category of slow flow vascular malformations and are associated with various familial syndromes and localized intravascular coagulation. Venous malformations were often misdiagnosed as hemangiomas; however, the treatment modalities of vascular malformations and hemangiomas vary significantly.

Heroin-induced leukoencephalopathy: Chasing the imaging findings.

We present a case of a 29-year-old male who was brought into the hospital due to unresponsiveness and found to have heroin inhalational leukoencephalopathy (HLE). HLE is one component of a broad spectrum of opioid encephalopathies that is associated with heroin inhalation and other opioids. There is considerable overlap of HLE with other toxic and hypoxic-ischemic encephalopathies; however, the specific territories of brain involvement help distinguish it from other cerebral insults.
