Locations of Misidentified Intracranial Hemorrhage

"In an article by W.M. Strub et al in American Journal of Neuroradiology 28:1679-1682 did an interesting review on the patterns of error of radiology residents in the detection of intracranial hemorrhage on head CT examinations while on call. Radiology residents prospectively interpreted 22,590 head CT examinations out of which there were a total of 1037 discrepancies identified, of which 141 were due to intracranial hemorrhage. The most common types of intracranial hemorrhage that were missed were subdural and subarachnoid hemorrhage. The most common location for missed subdural hemorrhage was either parafalcine or frontal. The most common location of missed subarachnoid hemorrhage was in the interpeduncular cistern. "
