Junior call case 8
1. Left inferior orbital wall blow-out fracture. This is concerning for inferior rectus muscle entrapment. - 22. Asymmetric hyperdensity of the right tentorium. DDx: small right subdural vs normal variant.
- Rectus muscle entrapment is a clinical diagnosis. Clinical signs and symptoms of entrapment can occur with or without CT evidence of rectus muscle herniation. Therefore, clinical correlation is important for any orbital wall fracture.
- Sagittal and coronal reformatted planes are critical for visualization of the fracture and the adjacent soft tissues.
- A hyperdense fluid level in any sinus is highly suggestive of an associated bony fracture.
- For subdural hematomas, always look carefully along the falx and tentorium, the latter of which is cut obliquely in the axial plane, “fans out” over the cerebellum, and can be easily missed.
