This is a long shot, and I agree these look more like phleboliths, but have you considered a parasitic infection?
Parasites that are present as calcifications within the soft tissues:
� Cysticerosis (tacnia solium)- Invasion of human tissue by the larval form of the pork tapeworm- Typically produces multiple linear or oval calcifications- usually have non-calcified central area, long axis is in plane of surrounding muscle bundle- intracranial involvement as well� Guinea Worm (Dracunculus medinensis)- serpinginous calcifications coiled in soft tissue, can be several feet long- more common in lower extremities due to life cycle- calcification frequently segmented because of muscle movement � Loa Loa (Filiaria banerofta)- calcified dead worm appears coiled -> thread-like density- difficult to visualize -> best seen in web spaces of hands or feet� Trichinosis (Trichinella spiralis)- calcification of encysted larvae (< 1 mm)- difficult to detect radiographically� Hydatid disease (Echinococcus)- infrequent calcification in cysts

Dear Colleagues I have questions regarding a patient, Caucasian, female, 44 years-old, submitted to cone beam tomography for analysis of the maxilla to implant planning. I found an area of calcification in soft tissue. See attached pictures 1-5. It is located above the ramus of mandible, internally to the zygomatic arch, between the condyle and coronoid process. It could be a phlebolite ("a small calcareous concretion formed in a vein")? The same patient has calcifications in other places (picture 6) - same side. I think that they represent: salivary calculi (sialolith) from submandibular gland and paraoral soft tissue calcifications (tonsillolith - calcification of tonsilar lynphoid tissue)I want to know the opinion of you. Thank you for your reply. -- Allan AbuabaraDDS, Specialist in Oral & Maxillofacial Radiology.Joinville, SC - Brazil.
