"Disproportionate oedema associated with this type of meningioma can results in unexpected postoperative complication so extended sedation, aggressive treatment of peritumoural cerebral oedema, and a lower threshold for postoperative imaging are required for this type of meningioma; hence, it is very important to recognise the imaging pattern and warn clinicians before operation so intra-operative frozen sections can be performed and subtype of the tumour determined prior to the transfer of the patient to the ICU for early and more aggressive initiation of the post-op treatments."

"It is not clear that epidemiology, clinical presentation, treatment or prognosis differ substantially from more common 'typical' meningiomas, and this information is not repeated here."
"Secretory meningiomas histologically are seen to contain glandular lumina with periodic acid-schiff (PAS)-positive, eosinophilic secretory globules (also known as pseudopsammoma bodies), which may be the cause of the frequently encountered peritumoural oedema 1,2. These pseudopsammoma body inclusions are cytokeratin (CK) and carcinoembryonic antigen (CEA) positive 2. Of note in at least some patients, elevated levels of CEA are detectable in peripheral blood 2."
