Here is a case of a sublingual solid mass lesion. The CT picture is similar to cystic lesions (ranula, retention cyst, epidermoid cyst, others) that are much more common than solid lesion in this location, however,  MRI was superior in demonstration of the lesion signal and enhancement

Differential diagnosis includes:

• Pleomorphic adenomas of the salivary glands are benign tumors present as well-circumscribed masses, most commonly located within the parotid gland, hypoechogenic on ultrasound, and bright on T2WI with homogeneous enhancement on MRI. The sublingual gland is the least common salivary gland to be involved 0.5%
• Hemangioma: considering intense bright signal in T2

Unfortunately, no available histopathological proof
