Right nasolabial lesion with remodeling of the maxillary alveolus bone. On MRI it shows high signal intensity on both T1- and T2-weighted images with no signal suppression on the T2 FLAIR with Fat saturation sequence. Differential Diagnosis:
Nasolabial cyst with hemorrhage
Epidermal inclusion cyst
* Benign proliferative condition affecting the synovial membrane. Most commonly monoarticular
* MRI: Mass-like synovial proliferation with lobulated margins and articular erosions
– Signal -> T1: low-intermediate ; DPFS/STIR: heterogeneous with areas of high signal ; GE: blooming artifact ; T1GD: variable enhancement.
