Radiographic evaluation of reactive osteitis in traumatic injury of sacroiliac joints.

Objectives: After traumatic Sacroiliac (SI) joint injury, follow up radiographic imaging can demonstrate subchondral bone resorption resembling inflammatory sacroiliitis. No studies have described the incidence of marginal SI post-traumatic osteitis, the probable temporal relationship to the initial traumatic injury, or the possible effect of unilateral hardware fixation on the contralateral SI joint.

Methods: A Level 1 trauma center imaging database was queried to identify patients with pelvic bony trauma between 2005 and 2017 with CT baseline preserved SI cortication and unilateral/bilateral traumatic SI diastasis.

Imaging of pediatric pelvic neoplasms.

Pediatric pelvic neoplasms, although relatively uncommon, are often difficult to evaluate and characterize with imaging, due to their overlapping appearances. This article discusses key clinical features and imaging findings that help limit the differential diagnosis of pediatric pelvic neoplasms. Testicular, ovarian, uterine, and bladder masses are included in addition to sacrococcygeal teratoma.

Torsed pulmonary sequestration presenting as a painful chest mass.

Pulmonary sequestration is a congenital abnormality that can be divided into intralobar or extralobar types. Both types are characterized by pulmonary tissue that does not communicate with the bronchial tree or pulmonary arteries and typically has its arterial supply arising from the descending aorta. We report a case of an 11-year-old girl with extralobar sequestration who presented with torsion causing abdominal pain and pleuritic chest pain.
