Meaning
A pathological dilation, expansion, or distention of a tubular structure or hollow organ in the body.
Less commonly, any abnormal stretching or widening of a bodily structure. In ophthalmology, it specifically refers to a thinning and bulging of the cornea.
Linguistics
Semantic Notes
Always refers to an abnormal, pathological state, not a normal physiological dilation. It is often part of a compound term specifying the affected structure (e.g., 'corneal ectasia', 'aortic ectasia').

FAQ
Frequently Asked Questions
No, it is a very low-frequency, specialised medical term unlikely to be encountered in everyday conversation.
No, 'ectasia' is strictly a noun. The related adjective is 'ectatic'. There is no common verb form; one would use phrases like 'become dilated' or 'undergo ectasia'.
Both involve dilation, but 'aneurysm' implies a more localised, sac-like bulging, often with a higher risk of rupture. 'Ectasia' is a broader term for diffuse dilation and may be a precursor or a milder form.
In American English, it is pronounced like the 's' in 'vision' or 'pleasure' (the /ʒ/ sound): 'ek-TAY-zhuh'.
