Case contributed by A.Prof Frank Gaillard


Low pressure headache suggestive of CSF leak.

Patient Data

Age: 40 years
Gender: Female
Nuclear medicine


Increased activity is noted on the left at C1/2 level. This should not be interpreted as being the site of leakage, as CSF in the epidural space can ascend and exit the canal at this level. It is known as a false localizing sign, also encountered on CT myelography. 

Case Discussion

This patient had a thoracic calcified disc eventually identified as the cause and was treated successfully with a blood patch.
