BACKGROUND Rotator cuff unit plays an important role in the normal functioning of the shoulder joint and any injury to these muscles will lead to potential clinical consequences. Hence, it is necessary to understand its anatomy, functioning and to identify any deviation from its normal pattern in imaging. For this, MRI of shoulder joint gives us the required information in detail without actually subjecting the patients to ionizing radiation.
Ameloblastic carcinoma has been described as an ameloblastoma in which there is histological evidence of carcinoma in a primary or recurrent ameloblastoma. The frequency of the lesion is estimated to be less than 1% of all ameloblastomas occurring in the mandible and maxilla.1 We present a case of a 30-year-old woman who presented with painless swelling of left upper face and recurrent upper respiratory tract infections. She was evaluated with CECT, MRI and PET-CT which showed 3.6 x 3.5 x 3.3 cm mass arising from the inferomedial wall of left orbit with sunburst periosteal reaction and cloudy osteoid matrix which was thought to be an osteosarcoma. She underwent a transorbital and trans nasal endoscopic wide local excision of the lesion which was then diagnosed as ameloblastic carcinoma on histopathology. Imaging features and pathological findings of the tumor along with novel treatment strategies and differential diagnosis are discussed in this case report.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
