Acute suppurative sialoadenitis is now rare because of the progress of antibiotics. Four patients with acute suppurative Sialoadenitis visited our clinic. Three had parotitis, and one had submaxillary gland infection.
All four patients were 70-80 years old. One of them had leukemia. Staphylococcus aureus was isolated from three patients.
It is difficult to differentiate between acute suppurative sialoadenitis and salivary gland malignant'. We recognize various images in CT scans of acute suppurative sialoadenitis, from tumor formation to total salivery gland swelling, so differentiation is difficult by CT scan.
We examined one patient with MRI, and we noted a great increase in the signal level of the salivary gland, which indicated inflamation and a low signal level which indicated abscess. MRI is considered to be useful for the differentiation between acute suppurative sialoadenitis and salivary gland malignancy
