From: An atypical imaging characteristic of calvarial metastasis of neuroblastoma as multiple multi-loculated cystic masses with internal blood-fluid levels: a case report

Fig. 1

Brain MRI with and without contrast media administration [a to h] revealed multifocal multi-loculated cystic lesions in the epidural space [white arrows in all images] containing fluid–fluid levels [dashed white arrows in a, b and c] which the dependent fluid was hyperintense on axial T1w and FLAIR [b and c respectively] and hypointense on axial T2w [A] sequences compatible with blood representing blood-fluid level. Diffuse pachymeningeal enhancement and enhancement of wall and septa of lesions are noted on axial contrast-enhanced T1w sequence [f]. Image [g] shows involvement of overlying calvarial bones as hyperintense signal change on axial T2 w sequence [dashed white arrows]. DWI and ADC map sequences [e and d] show no restriction. Image [h] is coronal contrast-enhanced T1w sequences showing similar large epidural metastatic lesion around flax [white arrow], note the calvarial involvement of frontal bone as abnormal bone and adjacent dural enhancement with overlying enhancing soft tissue component [dashed white arrow]. Follow up CT scan after chemotherapy treatment [i] shows complete resolution of meningeal lesions. Image j shows low attenuating soft tissue mass in left adrenal gland [black arrow]
