Abstract
We thank Dr Linn for her response to our letter entitled “Extracranial Internal Carotid Artery Stenosis as a Cause of Cortical Subarachnoid Hemorrhage.”[1][1] We certainly agree that cerebral amyloid angiopathy (CAA) is an important cause of focal sulcal subarachnoid hemorrhage (fsSAH) in the
Highlights
A recent study of the Boston criteria by Linn et al[2] demonstrated that the addition of SS as a diagnostic criterion improves the sensitivity for identifying CAA-related hemorrhage to 94.7%
In our case in which there was no MR imaging evidence of CAA, the likelihood of CAA should be low if the study is correct
The Boston criteria and the modified version proposed by Linn et al[2] require that other causes of intracranial hemorrhage be excluded.[3]
Summary
A recent study of the Boston criteria by Linn et al[2] demonstrated that the addition of SS as a diagnostic criterion improves the sensitivity for identifying CAA-related hemorrhage to 94.7%.
