[The joint management of Geriatrics-Neurosurgery of patients older than 75 years reduces the average stay, morbidity, hospital readmissions and mortality per year].

Objective: Population ageing is a reality for which national health systems are not adapted. The World Health Organisation has already raised awareness about the implementation of specific measures, from undergraduate training to dedicated elderly care units, to tackle this situation. In this article, the aim is to analyse the potential benefits of geriatric monitoring on elderly neurosurgical patients.

Neurosarcoidosis presenting with isolated intracranial mass lesion and communicating hydrocephalus.

Isolated neurosarcoidosis is a very rare disease, which makes up 5-15% of sarcoidosis cases. Hydrocephalus is a rare clinical feature with a prevalence of 6% among these patients. Considering neurosarcoidosis in the differential diagnosis of a unique parenquimal mass lesion could help in the early identification of this disease.

Remote cerebellar hemorrhage caused by undetected dural tear after lumbar spinal surgery.

Remote cerebellar haemorrhage is a rare but serious complication after spinal surgery. Although the mechanism is not well known, it always occurs after loss of cerebrospinal fluid due to dural tear, not always identified, which produces remote venous bleeding. Prognosis depends largely on the severity of this bleeding.
