Female 55 years old Reason: head and neck cancer, metastatic, with bone pain in left hip/spine There is a mass within the left ilium resulting in expansile remodeling of bone representing patient's known metastasis. The signal intensity of the lesion is heterogeneous on T1 and T2-weighted images with enhancement following gadolinium administration. There is mild enhancement of adjacent iliacus muscle. The remainder of the left ilium and lateral one third of the sacrum is predominantly yellow marrow which likely reflects radiation treatment effect. There are multiple foci of abnormal signal intensity and mild enhancement in the right iliac wing, and sacral body likely representing metastatic disease. There are also tiny foci of abnormal signal intensity and mild enhancement in the proximal right femur which may represent metastases.There is compression deformity of L3 with abnormal signal in the underlying bone presumed to represent pathologic fracture; please refer to lumbar spine MR report. Fibroid uterus is again noted.
Metastatic disease involving the bones of the pelvis and other findings as described above.
