Abstract

Background: The floor of the mouth (FOM) is located below the tongue in the oral cavity. Many diseases can occur in the FOM that are unique to this anatomical location.

Objective: To assess the role of CT in assessing lesions of the floor of the mouth with complementary US or MRI if needed.

Subjective: The study was carried out on 26 patients referred to the Radio-diagnosis department at Alexandria Main University Hospital diagnosed with the floor of mouth lesions during the time period December 2018 to September 2020. Biphasic CT was performed in all 26 patients with an initial non-contrast phase taken before contrast administration. Complimentary MRI was done in 8 cases along with complimentary ultrasound in 12 cases.

Results: MDCT helped in classifying lesions according to the nature of the lesion into three groups: cystic, solid and mixed lesions. Solid lesions were the commonest; fourteen (53.8%) of the lesions were of solid nature, seven (26.9%) were cystic in nature and lastly five (19.2%) lesions were of mixed nature. Nineteen (73%) lesions were well defined on MDCT, while seven (26.9%) lesions showed ill-defined borders.


Conclusion: CT is within reach with rapid image acquisition; this is why it is a primary investigation to broadly differentiate between different pathological processes in the floor of the mouth. Based upon the MDCT characteristics of the lesion such as tissue density, tissue composition, enhancement pattern, and vascularity.
