Vertebral artery dissection and stroke after scuba diving Sir, A 27‑year‑old man without past medical history developed vertigo and gait imbalance two hours after diving in cold water. The magnetic resonance imaging revealed ischemic lesion in the right side of medulla oblongata in the area of right posterior inferior artery (PICA). Computerized tomography‑angiography (CTA) showed right vertebral artery (VA) dissection [Figure 1a and b]. Six months later patient had no symptoms and the neurological examination was normal. The follow‑up magnetic resonance examination showed partial regression of the previous ischemic lesion and the CTA revealed normal right VA [Figure 1c and d]. The association

An unusual cause of low backache: Lumbar interspinous bursitis Sir, A 52‑year‑old male presented with low back pain of considerable intensity. Pain was essentially localized to lower lumbar region and got exaggerated on spinal extension. There was no history suggestive of radiculopathy or claudication. Magnetic resonance imaging (MRI) of lumbo‑sacral spine revealed inflammatory fluid‑like hyperintense signal in the interspinous ligaments at L3‑4 and L4‑5 levels on short tau inversion recovery (STIR) images [Figures 1a and b]; consistent with interspinous bursitis. Lumbar interspinous bursitis, also called Baastrup disease, is characterized by close approximation and contact of adjacent spinous processes (kissing spine) with resultant enlargement, flattening, reactive sclerosis of apposing interspinous surfaces forming neo‑articulation. [1,2] Repetitive strain on the interspinous ligaments is thought 711
