Intraspinal dermoid cyst

Case contributed by Dr Ian Bickle


Renal mass on ultrasound.

Patient Data

Age: 85 years
Gender: Male

4.5cm left lower pole renal mass.

Non enhancing mixed attenuation lesion in the spinal canal at the level of T12.


2.5 cm intradural, extramedullary mass dividing the filum terminale just distal to the conus.  Fat and soft tissue composition.  No enhancement.

4.5 cm left lower pole renal tumor.

Case Discussion

The appearances are in keeping with an incidental spinal dermoid cyst identified at the time of assessing for a renal mass (a renal cell carcinoma).

This is one of the less commonly observed intradural, extramedullary masses.
