WHXR QA Meeting 070327 - Slide14 Haemorrhage or calcification? (7 of 17)
The logical conclusion was given that this was not a simple haemorrhage, and a differential diagnosis of vascular anomaly or (less likely) tumour was offered.
While a vascular anomaly can give this appearance, it would most likely be a cavernous angioma rather than a capillary haemangioma, which is a rare lesion that, in the CNS, occurs mostly in the spine. The reporting radiologist may have meant a capillary telangiectasia, but these are mostly in the brainstem and are rarely if ever visible at CT imaging. The suggestion of a neoplasm (even as a "less likely" diagnosis) was probably not warranted by the appearance and stability of the lesion, especially in the absence of any clinical concern or relevant provided history.
