To evaluate the benefit of fluoroscopy-guided lumbar spine interventional procedures in treatment of low back pain. ⋯ Lumbar injections improved pain/disability related to discogenic lumbar spinal diseases. Efficacy of facet and sacroiliac injections is limited.

Comparative Study
Apparent diffusion coefficients of sacroiliitis in patients with established ankylosing spondylitis.
To compare apparent diffusion coefficients (ADCs) of sacroiliac joints (SIJs) in ankylosing spondylitis (AS) patients during advanced-active and advanced-nonactive stages. ⋯ ADCs lower than 0.69 × 10-3 mm(2)/s, obtained at subchondral aspect of SIJs of established AS patients with chronic changes, which this number represents the receiver operating characteristic (ROC) best cutoff value, can be considered as normal without possible residual inflammation of concern.

Spontaneous spinal cerebrospinal fluid (CSF) leaks are increasingly recognized in patients presenting with orthostatic headache and ultimately diagnosed with intracranial hypotension. While the precise cause of these spontaneous leaks is unknown, it is thought to result from underlying weakness in the spinal meninges and may be associated with meningeal diverticula or Tarlov cysts. Rarely, calcified intervertebral discs or bony osteophytes can result in CSF leakage, which has been described in the surgery literature but not well recognized in the radiology literature. The authors present three cases of patients presenting with CSF leaks from calcified thoracic disc protrusions that were successfully treated with epidural blood patches.

Case Reports
Petrosquamosal sinus in the temporal bone as a cause of pulsatile tinnitus: a radiological detection.
We report a newly evidenced cause of venous pulsatile tinnitus--the petrosquamosal sinus in the temporal bone. We also present the case of a 45-year-old woman who presented with an incapacitating objective pulsatile tinnitus in the left ear for 10 years. The radiology evidenced a petrosquamosal sinus in the air cells of the left temporal bone. The symptoms of pulsatile tinnitus disappeared completely after surgical treatment.

Case Reports
A rare but radiographically recognizable cause of an irreducible hip fracture-dislocation.
Hip dislocations are emergently reduced to decrease the chance of avascular necrosis of the femoral head. However, in some situations, the dislocation may be irreducible by a closed technique. ⋯ This rare type of irreducible fracture-dislocation demonstrates unique physical and associated radiographic findings. These fractures are important to recognize early, as attempts at closed reduction can lead to femoral neck fractures.
