Brain Midline Shift Measurement and Its Automation: A Review of Techniques and Algorithms by Chun-Chih Liao, Ya-Fang Chen, Furen Xiao

“…Being a sign of increased intracranial pressure, MLS is also an indicator of reduced brain perfusion caused by an intracranial mass or mass effect. We review studies that used the MLS to predict outcomes of patients with intracranial mass. …”

Bone within bone as a calcified chronic extra-dural hematoma mimicking ossified chronic subdural hematomas: a rare case report in pediatric patients by Mohan Karki, Yam Bahadur Roka, Abhinash Jha

“…Abstract Background Calcified chronic extra-dural hematoma is a rare presentation which often can be observed in traumatic or ventriculoperitoneal shunt cases; it can result in mass effect and raised intracranial pressure. It is common in young adults presumably due to relatively lax adhesion of dura to calvarium. …”

Paraneoplastic anti-Yo antibody mediated subacute cerebellar degeneration. Case series and literature review by M. Vaišvilas, R. Mameniškienė, A. Barkauskienė

“… Paraneoplastic neurologic syndromes are a subgroup of diseases due to indirect cytotoxic effects of the immune system on specific brain structures rather than the mass effect itself. Paraneoplastic anti-Yo antibody mediated subacute cerebellar degeneration is characterised by an insidious onset, a characteristic neurologic syndrome of cerebellar dysfunction, normal or near/normal brain imaging on MRI, and gynaecologic malignancies identified by thorough investigation in middle aged post-menopausal women. …”
