RESUMO
We describe a unique case of a 38-year-old female who presented at the emergency room due to a minor sacral fracture and local pain complicated by an initially undiagnosed cerebrospinal fluid (CSF) leak. This case emphasizes the importance of radiologists being attentive to subtle imaging findings of CSF leaks on computed tomography (CT) examinations, even in cases of low-energy traumas, as well as the complementary role of a dedicated magnetic resonance (MR) imaging protocol for such diagnosis.
RESUMO
Ulnar collateral, radial collateral, lateral ulnar collateral, and annular ligaments can be injured in an acute trauma, such as valgus stress in athletes and elbow dislocation. Recognizing normal anatomy in magnetic resonance imaging and ultrasonography studies is important to identify ligamentous abnormalities in these imaging modalities.
