9-year-old, female, Maine C**n was presented with recurrence of a peripheral vestibular syndrome. A ventral osteotomy of the left tympanic bulla was previously performed. An MRI of the head was performed.
There is a lesion extending from the horizontal portion of the left external ear canal, adjacent to the tympanic membrane (orange arrows), occupying the tympanic bulla (pink arrows) with intracranial extension, as an extra-axial lesion (blue arrows). The lesion shows a mixed signal intensity on T2W, mainly hyperintense compared to the musculature, is slightly hyperintense on T1W and has a marked and homogeneous post-contrast enhancement. The lesion also affects the soft tissues adjacent to the tympanic bulla (green arrows).

Associated with this lesion, there is a mild expansion of the tympanic bulla, with thickening of its wall (pink arrows). In addition, there is a defect in the ventral aspect of the wall of the bulla, corresponding to the location of the previous osteotomy described in the history (yellow arrow).

There is marked permeative osteolysis along the distal diaphysis of the femur, with disruption and thinning of the cortex (green arrows) with a wide transition zone. At this level, there is a soft tissue lesion with moderate contrast enhancement affecting the medullary cavity of the bone (pink arrows).
