[3] Cerebral microhemorrhages is a smaller form of hemorrhagic parenchymal contusion and are typically found in white matter. Such microhemorrhages are ...
Hemorrhagic transformation is a process which involves the bleeding of brain tissue that has been affected by the stroke and can take two forms: petechial hemorrhage and parenchymal hemorrhage. [ 1 ] HT can lead to further damage to the brain tissue and worsen the outcome of the initial stroke.

A chest X-ray showing right sided (seen on the left of the picture) pulmonary contusion associated with rib fractures and subcutaneous emphysema. Chest X-ray is the most common method used for diagnosis, [37] and may be used to confirm a diagnosis already made using clinical signs. [20] Consolidated areas appear white on an X-ray film. [42]
