1. Osteoid Osteoma RF Ablation

Osteoid osteoma is a benign bone neoplasm with a reported incidence of 2-3% among all bone primary tumors. Although it is a small and benign lesion, it is often cause of patient complaint and discomfort. It is generally characterized by a long lasting, unremitting pain that typically exacerbates at night, often leading to sleep deprivation and functional limitation of the skeletal segment involved, with a significant reduction of patient daily life activities and consequent worsening of the overall quality of life. Over decades, complete surgical resection has represented the only curative treatment for symptomatic patients. In the last years, new percutaneous ablation techniques, especially radiofrequency ablation, have been reported to be a safe and effective alternative to classical surgery, with a low complication and recurrence rate, and a significant reduction in hospitalization cost and duration. The aim of this article is to provide an overview about the radiofrequency thermal ablation procedure in the treatment of osteoid osteoma.

2. Hemangioma Sclerotherapy

Sclerotherapy is a simple, technically easy and effective mode of treatment for infantile hemangiomas (IH). It acts by blocking the growth of actively proliferating lesions, by targeting their vascularity accelerating their regression. Polidocanol is a commonly used sclerosant. We report two interesting cases of IH treated solely with polidocanol sclerotherapy and discuss the unique place this modality has in the armamentarium against IH. Sclerotherapy was found to be especially useful for large, exuberant and pedunculated lesions, producing rapid regression and preventing the disfiguring sequelae which are likely if large or pedunculated lesions are left to involute on their own.
