ABSTRACT
Butterfly vertebras are an abnormal embryological formation of the spinal bodies that occur because of a lack of fusion of the chondrification centers of the vertebral bodies. Langerhans cell histiocytosis is an entity that frequently involves vertebral bodies resulting in flat vertebras, and recovery of the vertebral body height is a very unusual finding. We present a case report of a pediatric patient with a thoracic acquired butterfly vertebra which occurred secondary to a Langerhans cell histiocytosis involvement. It is extremely rare to find vertebra plana that regains its complete height but is even more infrequent to evidence of a butterfly vertebra deformity that is not congenital.

Anterior clinoid process (ACP) mucoceles are an uncommon entity and an even rarer cause of visual impairment. We review the case of a 62-year-old female with a 2-year history of progressive right-sided monocular vision loss. Paranasal sinus computed tomography (CT) scan showed bilateral ACP pneumatization. A soft tissue density mass occupied the right ACP with bone expansion and compression of the right orbital canal. An endonasal approach was performed with total vision recovery. Dedicated images are necessary to diagnose ACP. On CT, the affected sinus will have bone erosions. On magnetic resonance imaging, the signal intensity is determined by its protein concentration and mobile water protons. ACP mucoceles' accurate diagnosis determinates the treatment and surgical approach. Finally, the correct management selection will determine the retrieval of the visual ability.
