Clunealgia is caused by neuropathy of inferior cluneal branches of the posterior femoral cutaneous nerve resulting in pain in the inferior gluteal region. Image-guided anesthetic nerve injections are a viable and safe therapeutic option in sensory peripheral neuropathies that provides significant pain relief when conservative therapy fails and surgery is not desired or contemplated. The authors describe two cases of clunealgia, where computed-tomography-guided technique for nerve blocks of the posterior femoral cutaneous nerve and its branches was used as a cheaper, more convenient, and faster alternative with similar face validity as the previously described magnetic-resonance-guided injection.

To assess interobserver agreement between thoracic radiologists, radiology residents, and emergency physicians in diagnosing pulmonary embolism (PE). ⋯ Important differences in interobserver agreement were found, with emergency physicians tending to overdiagnose PE.

To discuss the rare finding of bronchial artery aneurysms and pseudoaneurysms as well as describing available endovascular treatment options. ⋯ Bronchial artery pseudoaneurysms are rare but have a chance of rupture. Percutaneous embolization is a reasonable treatment option for these patients.
