A boy in middle childhood with a history of early morning headaches presented to secondary care after being found to have bilateral papilloedema by his community optometrist. CT head showed a large right-sided heterogeneous calcific and haemorrhagic mass causing marked mass effect and midline shift. Preoperatively, the lesion was characterised on MRI as a haemorrhagic mass with a 'popcorn' appearance suggestive of a giant cavernous malformation measuring 6.

The widespread calcific deposits within the brain tissue that characterize Fahr's syndrome develop secondary to different underlying conditions such as parathyroid disorders, brain infections, and toxic exposures. Hypoparathyroidism, a rare disorder of calcium and phosphate metabolism, is the most commonly identified etiology of Fahr's syndrome.

Prenatal infection of Zika virus was found to be associated with microcephaly, arthrogryposis, intracranial calcifications, fetal growth restriction, and fetal demise.

Aicardi-Goutières syndrome (AGS) is a genetically heterogeneous type-I interferonopathy presenting in infancy with intracranial calcifications, white matter lesions, and brain atrophy. AGS7, caused by gain-of-function (GOF) mutations in the IFIH1 gene, triggers excessive type-I interferon production, leading to autoimmune responses. We describe an 18-year-old female diagnosed with AGS7 due to a somatic GOF mutation in IFIH1.

The management of unruptured intracranial aneurysms (UIA) involves assessing the risk of rupture, which requires a thorough understanding of risk factors such as the geometric characteristics of the neck (neck size) or local structural heterogeneities. This study explores the impact of neck size on the rupture risk of the aneurysmal sac and examines how local heterogeneities, such as calcifications or variations in tissue composition, influence the mechanical response of the wall of a saccular aneurysm during the insertion of an innovative arterial wall deformation device (DDP). The results reveal that high aspect ratios (AR) are associated with increased hemodynamic stress, thereby raising the risk of rupture.
