The lesion appeared hypointense with the grey matter on Tl-weighted images (figure lA). In this same sequence, a peripheral halo of hypersignal due to haemoglobin metabolites was also evident toward the white matter. The lesion was inhomogenesously hyperintense on PD (figure lB) and T2-...
cerebellitis, MRI is often unremarkable at presentation, even though T2/FLAIR hyperintensity of cerebellar hemispheres can be seen, while a more typical imaging finding is paraneoplastic cerebellar degeneration (PCD), consisting in cerebellar atrophy at follow-up, manifesting months to years later [29]...
Direct findings include focal interruptions in the hypointense myometrial border at sites of placental invasion (Baughman et al., 2008). The soft tissue resolution of MRI allows for increased sensitivity for extra-uterine invasion in cases of PAS Grade III which can be essential for surgical ...
The relation of the hypointense vein (black arrow) with the demyelinating plaque is better depicted with the FLAIR* image, which is calculated as the prod- uct of the coregistered T2-FLAIR and SWI images. Lesion probability map obtained with brain MRI in a group of patients with multiple ...
A brain MRI, requested to characterize the suspected lesion con firmed the presence of a right temporal rounded cystic lesion (42x33x31 mm) which appeared hypointense in T1 and hyperintense in T2, with an inferior and lateral solid part (20 mm of maximum diameter) (Figure 2C– F(i)...
On magnetic resonance imaging, aspergilloma is hypo intense in both sequences T1 and T2 because of the lack of water and the high content of proteins of the fungus ball (Gustafson and Bansberg, 2000). The cause of aspergillomas remains obscure, and the role of dental filling material is ...
DNET is a benign mixed neuronal-glial tumor causing drug-resistant epilepsy primarily in children and young adults. The typical radiological pattern is a magnetic resonance imaging (MRI) T1-hypointense, T2-, and fluid-attenuated inversion-recovery hyperintense multicystic lesion involving the cerebral ...
Typically, PLGFSs are hypo- or isointense in relation to muscle in T1 MRI and show heterogenous high-intensity signals in T2 MRI. Hemorrhages may occur occasionally [133]. Liang and Xu reported on a case of a PLGFS patient. The MRI revealed a cystic solid tumor with a hypointense central...
