•  Conventional CT/MRI may fail to identify the cause of spontaneous ICH in a non-hypertensive patient.
• Intra-arterial cone-beam CT angiography (CBCT-A) provided critical angioarchitectural detail, enabling precise endovascular planning.
•  Complete and complication-free nidus occlusion was achieved with Onyx 18, demonstrating the diagnostic and therapeutic value of CBCT-A in micro-AVMs.

• Bladder dysfunction can occur in association with lumbosacral spinal stenosis(LSS) and can create urinary reflow to the ureter and upper urinary tract lesions.
• Urodynamic studies (UDS) can aid in the primary diagnosis and assessment of cases with neurogenic bladder, as well as in targeting therapeutic modalities, especially for preventing renal dysfunction.
• There is a drastic improvement in maximum flow rate, post-voiding residual urine, and maximum cystometric capacity following surgical decompression.  

● Consider spinal fracture risk in every patient with AS, even after minor trauma. ● CT scan is the gold standard for spinal column trauma evaluation in AS patients.

● Literature favors surgical management with internal fixation in traumatic lumbar fractures in AS patients with the posterior or combined posterior-anterior approach.

● Spine surgery in AS patients needs careful pre-operative and intraoperative consideration to minimize complications
