Question
The child sustained a forehead injury one month ago and underwent a CT scan and MRI. The images show a ring-shaped short T2 signal in the left cerebellar hemisphere with an iron ring feature, measuring approximately 6.5 mm by 8.5 mm, with slightly blurred edges and a stippled, slightly longer T2 signal in the center. Magnetic susceptibility-weighted imaging (SWI) shows a low-signal node-like low signal, with an irregularly shaped piece of a long T1/T2 signal underneath, which appears as a low signal in FLAIR sequences. Please explain the significance of these imaging findings.
Answer
Based on the detailed MRI findings, it is considered to be a vascular abnormality, likely a cavernous hemangioma. This condition could be caused by trauma or congenital abnormalities. It is recommended that the patient follow the doctor’s advice for regular follow-ups or surgical treatment based on the condition and symptoms. This is a suggestion for the issue, and I hope it will be helpful to you. Wish you good health.
