Spinal meningeal diverticula in autosomal dominant
polycystic kidney disease
Lancet
(Apr) 349:1223-1224 1997

Patients with ADPKD may have intracranial aneurysm, hypertensive
intracerebral hemorrhage, or cervicocephalic arterial dissection. In
the present study (a letter to Lancet) a new cause is identified:
meningeal diverticula. Three of 178 ADPKD patients had such
diverticula. One presented with a 3-month history of headache and
visual blurring. The headache was aggravated by standing but
resolved spontaneously. Multiple thoracic level diverticula were
present. A second patient presented with low back pain and left leg
pain, with a diverticulum at L2-S1. A third patient had a 2 month
history of postural headaches and a spinal canal-pleural cyst.
