MR sialography of iatrogenic sialocele: comparison with conventional sialography

Abstract

Our preliminary results suggest that MR sialography is a robust, non-invasive method for demonstrating the ductal system up to second-order branches, the site of ductal injury and the focal cystic lesion. MR provided at least the same information as conventional sialography in the evaluation of site of communication but provided additional information about the sialocyst and upstream ductal system in five cases. Being a non-invasive modality, we recommend MR sialography as the investigation of choice in the evaluation of an iatrogenic sialocyst.

Parotid fistula from transparotid approach for mandibular subcondylar fracture reduction

“…On sialogram, the most effective diagnostic modality,[5] the defect was noticed in the parotid substance during rest and stimulation. Hence, this case had to be treated by surgery by internalization.…”

The Role of Magnetic Resonance Imaging and Magnetic Resonance Sialography in the Diagnosis of Various Salivary Gland Disorders: An Interobserver Agreement

“…MRI is the method of choice in patients with palpable salivary gland masses to assess the exact extent of tumors, invasion of neighboring structures, perineural spread, and lymph node staging [2,6]. However, MRI cannot be used to evaluate the duct system of the salivary glands [7].…”

“…MR sialography can also be performed during acute gland infection and in patients with known reactions to iodinated contrast material [10]. Moreover, upstream ductal systems can be visualized in cases of complete ductal obstruction [7].…”

Dynamic Scintigraphy With SPECT-CT of Postoperative Salivary Leak

“…X ray, echo, CT, and MR sialography or fistulography, and salivary gland scintigraphy have been used each with advantages and disadvantages. [5][6][7][8] There is no real accepted standard diagnostic sequence. Scintigraphy is commonly used to assess salivary gland function like in suspicion of Sjögren's syndrome.…”
