1848 W. H. Walshe in Todd's Cycl. Anat. & Physiol. IV. 139/2 Pseudo-tumours, composed essentially of epithelium, and susceptible of vascularization, form, it is affirmed, on some mucous surfaces.

1869 T. H. Tanner Pract. Med. I. iv. x. 426 Sometimes the pseudo-tumour has had its origin in syphilitic caries of the vertebræ.

1898 C. K. Mills Nerv. Syst. & its Dis. v. 503 Tuberous Sclerosis. An interesting form of sclerotic pseudotumor is sometimes found in the brain, especially among the idiotic..and epileptic.

1968 H. O. Mackey & J. P. Mackey Handbk. Dis. Skin (ed. 9) xxviii. 308 The Ehler's Danlos syndrome is a tetrad consisting of:—(1) hyperelasticity of the skin; (2) hyperlaxity of the joints. (3) fragility of the skin and blood vessels; (4) molluscous and pseudo-tumours following injury.

1993 Discover Aug. 6/3 He wrote about a woman with pseudotumors in the brain.

2. More fully pseudotumour cerebri. A syndrome characterized by increased intracranial pressure occurring in the absence of an intracranial mass or abnormality of the cerebral ventricles.
