Brain Capillary Telangiectasia: CT Calcification, MRI Enhancement, SWI Susceptibility, and the Critical Differential Diagnosis
Edited by ScholarGen MesiAI Team Executive Clinical Summary A woman in her 60s with a long history of headache underwent brain CT because her headaches had recently become more frequent. Neurologic examination revealed no specific abnormality. CT unexpectedly demonstrated a focal coarse calcification in the medial right inferior temporal region. At first glance, an intra-axial calcified lesion can raise a broad differential diagnosis, including previous infection, congenital abnormalities, vascular malformation, and chronic blood products or post-traumatic change. However, calcification itself is not a diagnosis. The critical diagnostic step is to correlate the CT finding with multiparametric MRI. In this case, MRI demonstrated a small enhancing lesion without a significant surrounding FLAIR abnormality, without diffusion restriction, and without a prominent T2 flow void. MRA showed no major high-flow vascular abnormality. Susceptibility-sensitive imaging provided an additional vascula...
