They are seldom misdiagnosed as chronic sialadenitis with
sialolith. The other differential diagnosis would be submandibular lymph node, plunging ranula and a second branchial cyst.
However, depending on the location of
sialolith (e.g., mainly in the duct of the submandibular gland), occlusal radiograph can be used for its visualisation [3, 8] if it is located in the glandular parenchyma; otherwise, other imaging examinations allow a better visualisation.
Giant
sialolith: case report and review of the literature.
When the patient exhibited only minimal improvement with conservative management, he was scheduled for
sialolith removal with general anesthesia in the operating theater.
(16-18) Sialocele has been reported in a yellow-naped Amazon parrot (Amazona ochrocephala auropalliata) associated with
sialolith (a calculus of the salivary system).
The presence of the
sialolith was confirmed on plain radiograph (Fig.
Some common affections of head related to oral cavity are tongue laceration (Kashyap et al., 2015), salivary ducts are ectasia of parotid duct, salivary fistula,
sialolith causing obstruction of salivary ducts and sialocele (Sagar et al., 2010, Misk et al., 2014).
(7,12) In cases where it is initially difficult to identify a lesion as a
sialolith or phlebolith, distinguishing features have been identified.
Pathological radio-opaque calcifications simulating tonsilloliths are of vasculature (atherosclerosis or phleboliths), lymph node calcification, calcified peritonsillar abscess, salivary gland
sialolith or an intraosseous abnormality within the mandibular ramus.

Thirdly, approximately 45% of plunging ranulas occur iatrogenically after surgery to remove oral ranulas or secondary to surgical procedures for
sialolith removal, duct transposition and implant placement.
