IMAGING OF MASS LESIONS OF TONGUE

ABSTRACT NO : 1171

AIMS & OBJECTIVES

• To demonstrate the role of Multi detector computed tomography and Magnetic Resonance Imaging in detection of mass lesions of tongue .

• To demonstrate their role in pre operative diagnosis and management.

MATERIALS & METHODS

• 29 patients with mass lesions in tongue are evaluated with CT or MRI for a period of 7 months from March 2014 till October 2014.

• CT - 64 Slice GE Contrast enhanced Axial, Coronal and Sagittal images

• MRI - 1.5 Tesla GE 16 channel MRI. Three plane T1 , T2 FS are basic sequences.

DEMOGRAPHIC DISTRIBUTION

SQUAMOUS CELL CARCINOMA

• Squamous cancers of gingivobuccalregion,oral tongue and retromolar trigone are common oral cancers in our country.

• Among these carcinoma tongue is the second most common .

• Lateral border- most common site.

• Staging is important in the management.

CONCLUSION

• Though MR is the sensitive imaging modality for tongue evaluation , CT is most commonly used in preoperative assessment and post operative surveillance.

• When CT and MRI are combined together the sensitivity and specificity of delineating tongue lesions is increased.

TAKE HOME MESSAGE

• CT -cortical erosions.

• MRI -soft tissue extension, bone marrow involvement and peri neural spread.

• CT and MRI are complementary in evaluating tongue lesions.
