Calvarial Langerhans cell histiocytosis in an Adult: Typical imaging findings in an atypical age group.

Langerhans Cell Histiocytosis (LCH) is a rare disorder characterized by neoplastic proliferation of Langerhans-type dendritic cells. LCH is most frequently encountered in the pediatric populations, and involvement of the skeletal system is a common manifestation. Herein, we report a case of LCH presented as an isolated skull lesion in a 66-year-old patient.

ACR Appropriateness Criteria Breast Cancer Screening.

Mammography is the recommended method for breast cancer screening of women in the general population. However, mammography alone does not perform as well as mammography plus supplemental screening in high-risk women. Therefore, supplemental screening with MRI or ultrasound is recommended in selected high-risk populations.

Intracranial Capillary Hemangioma in the Posterior Fossa of an Adult Male.

Intracranial capillary hemangioma (ICH) is a rare entity, with approximately 24 reported cases in the literature. There are only three reported cases of ICH in an adult male. In this case report, we describe the fourth documented case of ICH in an adult male and, to the best of our knowledge, the first ever documented case of ICH in the posterior fossa of an adult male.

Adrenal Incidentalomas: Clinical Controversies and Modified Recommendations.

Objective: A variety of imaging and clinical guidelines have been developed to assist radiologists and referring physicians in the workup of incidental adrenal masses. The objective of this article is to provide a concise review of incidental adrenal mass imaging and present the key differences between the available guidelines.

Conclusion: An alternative algorithm for the imaging and clinical workup of adrenal incidentalomas is presented in an attempt to bridge sometimes conflicting recommendations.

Patellotibial contusions in anterior cruciate ligament tears.

Bone contusions are an important ancillary finding of many knee injuries. Not only are they a source of pain, they may suggest a mechanism of injury or a specific derangement of the knee joint. We have encountered a small number of patients being evaluated for anterior cruciate ligament (ACL) tears with unexplained patellar and tibial edema at magnetic resonance (MR) imaging.
