The Value of Dynamic MRI Studies in Parotid Tumors

An accurate preoperative diagnosis of parotid tumors is essential for selection and planning of the surgical treatment. Various modern cross-sectional imaging and cytologic investigations can support differential diagnosis of parotid tumors. The aim of this study was to achieve a comprehensive and updated review of modern imaging and cytologic investigations used in parotid tumor diagnosis, based on the latest literature data. This literature review could serve as a guide for clinicians in selecting different types of investigations for preoperative differential diagnosis of parotid tumors. Magnetic resonance imaging (MRI) with its dynamic and advanced sequences is the first-line imaging investigation used in differentiating parotid tumors. Computed tomography (CT) and positron emission tomography (PET)-CT provide limited indications in differentiating parotid tumors. Fine needle aspiration biopsy and core needle biopsy can contribute with satisfactory results to cytological diagnosis of parotid tumors. Dynamic MRI with its dynamic contrast-enhanced and diffusion-weighted sequences provides the best accuracy for preoperative differential diagnosis of parotid tumors. CT allows the best evaluation of bone invasion, being useful when MRI cannot be performed, and PET-CT has value in the follow-up of cancer patients. The dual cytological and imaging approach is the safest method for an accurate differential diagnosis of parotid tumors.

Parotid Tumors

F.NA.C has been used for ages as a safe and economical tool for fast preoperative diagnosis of parotid tumors. It has certain pitfall which sometimes leads to misdiagnosis and consequently it may have affect on treatment of the tumors. Keeping in view of the diverse classification of parotid tumors’ information from cytology should be combined with radiology as well as clinical diagnosis. Aim: To discuss some cases where there was discrepancy between cytological diagnosis and histopathological result and also suggest measures to improve the efficacy of F.N.A.C. Material and methods: The study includes 50 cases of parotid tumours who presented to the department of ENT at Government medical college Haldwani which is a tertiary referral centre during 2009 to 2016. Only adult patients were included and inflammatory swelling were excluded from the study. All patients evaluated Contrast enhanced computerized tomography(CECT) and Magnetic resonance imaging (MRI) followed by Fine needle aspiration cytology .Preoperative diagnosis was made upon the findings of the above investigations and different types of parotid surgeries were done. . Final diagnosis was made on histopathological examination. Result :The most common tumour came out to be pleomorphic adenoma (23 cases-46%) followed by mucoepidermoid carcinoma(12cases-24%). In ten cases there was no clear cut association between cytological diagnosis and final histopathological diagnosis. Conclusion: FNAC is highly sensitive and specific technique for diagnosis of many salivary gland swellings. FNAC can be used preoperatively to avoid unnecessary surgery and biopsy. Details of clinical information and radiologic features may help the pathologist to arrive at the appropriate diagnosis and reduce false interpretation. Pitfalls may also occur with improper technique of FNAC which can be overcome by proper caution.

During 2011-2012, 56 patients diagnosed with parotid tumors were admitted to the Maxillofacial Surgery Department of “Lucian Blaga” University and in Euroclinic Hospital. 72% were benign tumors and 28% malignant. All patients received surgical treatment (total or partial parotidectomy). For the malignant tumors, radiotherapy was added to the modal treatment (94% of the cases). Pleomorphic adenoma was encountered in 70% of the benign cases, followed by Warthin tumor in 15%. Adenoid cystic carcinoma was noticed in 31% of the malignant cases, mucoepidermoid carcinoma in 25% of the cases, and squamous carcinoma and non-Hodgkin lymphoma on 12.5% of the malignant cases.

Migraine is currently considered a common pathology, which in many cases leads to a decrease in performance. Migraine diagnostics is the most important clinical, biomedical andsocial task. MRI studies are important in the diagnosis of migraine disease. Focal lesions are localized mainly in the white matter, which confirms the clinical nature of the disease. As a drug correction, the drug Sumamigren was proposed, the early intake of which allows avoiding migraine recurrence and transition to chronicity
