An alternative adjective form meaning 'relating to or characteristic of an aneurism,' used interchangeably with 'aneurismal' in older medical texts.
From aneurism (the noun) plus the adjective suffix -atic (from Greek -atikos), providing another way to form the descriptive adjective beyond the more common -al ending.
Medical terminology sometimes had multiple 'correct' ways to say the same thing—'aneurismal,' 'aneurismatic,' and 'aneurysmal' all existed at different times, which made medical writing confusing and is why modern medicine prefers standardized terminology.
