There are a number of common pain disorders that can be managed effectively by injections around or ablation of peripheral nerves. Ultrasound is a universally available imaging tool, is safe, cost-effective, and is excellent in imaging many peripheral nerves and guiding needles to the site of the nerves. This article aims to present an overview of indications and techniques of such procedures that can be effectively performed by a radiologist.

Aspergillomas are fungal balls developing in pre-existing lung cavities, which are most commonly secondary to tuberculosis. Aspergillomas can cause hemoptysis due to erosion of the blood vessels in cavity walls, which can often be recurrent, massive, and life-threatening. Bronchial artery embolization is considered to be the treatment of choice for short-term control of hemoptysis, and lobectomy as the definitive treatment for aspergilloma. We present a unique observation in two cases of aspergilloma where the fungal balls disappeared radiologically after bronchial artery embolization performed for massive hemoptysis.
