pneumatosisn.

Brit.

/ˌnjuːməˈtəʊsɪs/, U.S.

/ˌn(j)uməˈtoʊsəs/

Origin: A borrowing from Latin. Etymon: Latin pneumatosis.

Etymology: < post-classical Latin pneumatosis accumulation of air in the stomach or intestines (5th cent. in a medical writer; a1250 in a British source as neumatosis ), nervous activity (1664 in a British source) < ancient Greek πνευμάτωσις evaporation, in Hellenistic Greek also accumulation of air in the stomach or intestines < πνευματοῦν to turn into vapour, to blow up, inflate ( < πνευματ- , πνεῦμα wind, breath: see pneuma n.) + -ωσις -osis suffix. Compare French pneumatose generation of nervous activity in the brain (1665 or earlier), windiness of the stomach (1752 or earlier), accumulation of gas in the intestinal wall (in pneumatose intestinale: 1828 or earlier).

†1. Nervous activity; the generation of this. Obsolete. rare.

1684 tr. S. Blankaart Physical Dict. 233 Pneumatosis is the Generation of Animal Spirits, which is performed in the barky Substance of the Brain; the little Arteries there are emptied, and the Spirits distil, which after they are come as far as the middle of the Brain, they actuate and Invigorate all the Nerves.

2. Medicine. Abnormal accumulation of air or gas in a part of the body, esp. (more fully pneumatosis intestinalis, pneumatosis cystoides intestinalis) in the intestinal wall; an instance of this. Cf. emphysema n.
