Case Reports
Investigation of polymethylmethacrylate pulmonary embolus in a patient ten years following vertebroplasty.
Percutaneous vertebroplasty (PV) is a procedure commonly used for the treatment of vertebral compression fractures, and the number of procedures has been steadily increasing over the past decade. We report a case of an 81 year old female with a history of breast cancer that developed two vertebral body compression fractures and was subsequently treated with PV. ⋯ Ten years following the procedure, she remained asymptomatic with the PMMA embolus being discovered incidentally during workup for a suspected chronic obstructive pulmonary disease (COPD) exacerbation. In reviewing the case, we describe the typical presentation of a pulmonary PMMA embolus and consider methods to decrease the incidence of this complication.

Plunging ranulas are rare cystic masses in the neck that are mucous retention pseudocysts from an obstructed sublingual gland. They "plunge" by extending inferiorly beyond the free edge of the mylohyoid muscle, or through a dehiscence of the muscle itself, to enter the submandibular space. ⋯ We present a case of plunging ranula in a 44 year old female who presented with a painless, slowly enlarged neck mass. Plunging ranulas should be considered in the differential diagnosis of cystic neck masses, specifically when seen extending over, or through, the mylohyoid muscle.
