Intracranial Lesions with Low Signal Intensity on T2-weighted MR Images - Review of Pathologies.

Zimny A, Neska-Matuszewska M, Bladowska J, Sąsiadek MJ - Pol J Radiol (2015)

Bottom Line: In this article we presented intracranial pathological substances and lesions with low signal intensity on T2-weighted images.Eight groups of substances were discussed i.e. 1.Gadolinium-based contrast materials, 2. hemoglobin degradation products 3. melanin, 4. mucous- or protein-containing lesions, 5. highly cellular lesions, 6. lesions containing mineral substances such as: calcium, copper and iron, 7. turbulent and rapid blood or CSF flow 8. air-containing spaces.

ABSTRACT
In this article we presented intracranial pathological substances and lesions with low signal intensity on T2-weighted images. Eight groups of substances were discussed i.e. 1. Gadolinium-based contrast materials, 2. hemoglobin degradation products 3. melanin, 4. mucous- or protein-containing lesions, 5. highly cellular lesions, 6. lesions containing mineral substances such as: calcium, copper and iron, 7. turbulent and rapid blood or CSF flow 8. air-containing spaces. Appropriate interpretation of signal intensity as well as analysis of lesion location and clinical symptoms enable a correct choice of a further diagnostic algorithm or, in many cases, final diagnosis based exclusively on an MRI examination.

f15-poljradiol-80-40: Calcified meningioma in the left frontal location with a very low signal on T2-weighted image.

Mentions: Neoplasms such as meningiomas and gliomas are often associated with calcifications and thus provide appearance of hypointense foci on T2-weighted images (Figure 15).
