Hyperintense Perilesional Edema on T1-Weighted Imaging in Cavernoma: A Case Report.
Alturki et al., Cureus 2024

The case study highlights an atypical radiological feature of cerebral cavernous malformations (CCMs), which are vascular anomalies in the brain that resemble berry-shaped lesions. The focus is on a 35-year-old female patient who experienced progressive left-side weakness and nausea. The key radiological finding was hyperintense perilesional edema on non-contrast T1-weighted MRI images, which is not commonly associated with cavernomas.
This finding is significant because it suggests that such hyperintensity on T1-weighted images could be indicative of a cavernoma, thus contributing to the diagnostic criteria for these lesions. The patient underwent successful surgery to remove the hematoma and the cavernoma, indicating that recognition of this sign can lead to timely and effective treatment.
The importance of this case lies in its potential to enhance diagnostic accuracy for cavernomas, especially when atypical features are present on MRI scans. It adds to the literature by documenting a rare radiological sign that could be crucial for clinicians in identifying and managing cerebral cavernous malformations.
