Not exactly what you are looking for but similar flavor. The most obvious option to me is liar. claim, verb. state or assert that something is the case, typically without providing evidence or proof. purport, verb. to claim to be or do a particular thing when this claim may not be true.

Two-thirds of patients treated for otosclerosis are women. About 75 percent of all cases are bilateral. Otosclerosis often starts in an area anterior to the stapes footplate called the fistula ante fenestrum but can occur in any part of the otic capsule. The second most common site of origin is the round window. Histologically, otosclerosis is characterized by 2 phases: 1) otospongiosis; and, 2) otosclerosis. In otospongiosis, affected bone becomes hypervascular and osteoclasts and osteolytic osteocytes cause enlargement of the vascular spaces of the bone.
