Where available, sialography has also been useful in diagnosing RJP in the past, with the very characteristic patterns of multiple areas of punctate and globular sialectasis scattered throughout the glandular parenchyma.
Recurrent parotitis and sialectasis in childhood: Clinical, radiologic, immunologic, bacteriologic, and histologic study.
Chronic sialadenitis was diagnosed when there was change in the calibre of the duct, sialectasis.
Sialectasis was identified in two patients due to chronic sialadenitis due to obstructing calculus.
The parenchyma demonstrated a heterogeneous blush, but no focal sialectasis
Thus, it was assumed that the most likely etiology was sialectasis
, secondary to the prolonged history of a parotid tumor.
1) As acinar destruction progresses, salivary production decreases and ascending infections develop, eventually leading to sialectasis
developing in the gland, enlargement of the microcysts and fatty replacement of the destroyed acinar within the salivary gland parenchyma.
Recurrent parotitis (RP) is defined as recurrent parotid inflammation, generally associated with non-obstructive sialectasis of the parotid gland.
Sialographic studies have shown a combination of sialectasis, strictures, dilations, and kinks.
2,8,9) Ultrasonography is helpful when making a specific diagnosis such as sialectasis
Recurrent parotid insufflation can predispose the patient to recurrent parotitis and sialectasis
