The testis: the unusual, the rare, and the bizarre—pictorial review Stewart VR, Sidhu PS (P.S.S.: Department of Radiology, King’s College Hospital, Denmark Hill, London SE5 9RS, UK). Clin Radiol 2007;62:289–302. Ultrasound is the preferred technique when imaging the scrotal contents. Although appearances of many of the more common abnormalities present the examiner with no diagnostic difficulty, the more unusual conditions may present a considerable challenge. Many normal variants, as well as unusual and rare abnormalities, may be instantly recognized once seen. The current review highlights the more unusual and rare conditions affecting the scrotal contents in order to allow the reader the opportunity to gain knowledge of their existence and to aid future interpretation of the difficult examination. n 2007 The Royal College of Radiologists.

Percutaneous osteoid osteoma treatment with combination of radiofrequency and alcohol ablation Akhlaghpoor S, Tomasian A, Arjmand Shabestari A, Ebrahimi M, Alinaghizadeh MR (Noor Medical Imaging Center, Shahid Yosenand St., Motahari St., Tehran, Iran). Clin Radiol 2007;62:268–273. Aim: This article aims to assess the efficacy of percutaneous osteoid osteoma treatment using a combination of radiofrequency ablation (RFA) and alcohol ablation with regard to technical and long-term clinical success.

Materials and methods: From December 2001 to November 2004, RFA and subsequent alcohol ablation were performed on 54 patients with osteoid osteoma, diagnosed clinically using radiography and computed tomography (CT), as well as via the patients’ symptoms. Under general anesthesia, treatment was performed via percutaneous access under thin-section (2-mm) spiral CT guidance in all cases with an 11-G radiofrequency-compatible coaxial needle and 2-mm coaxial drill system and 1.0-cm active tip 17-G noncooled radiofrequency needle. RFA was performed at 908C for a period of 6 min. After needle removal, 0.5–1.0 ml absolute alcohol (99.8% concentration) was injected directly into the nidus using a 20-G needle. Patients were discharged within 24 h and followed up clinically (at 1 week, 1 month, and every 3 months thereafter). Results: The technical success rate was 100%. Complications occurred in two patients consisting of local mild cellulitis in entry site and peripheral small zone paresthesia on the anterior part of the leg. The follow-up period range was 13–48 months (meanFSD, 28.2F7.4 months). Prompt pain relief and return-to-normal activities were observed in 52 of 54 patients. Recurrent pain occurred in two patients after a 1and 3-month period of being pain free; a second RFA and alcohol ablation were performed, achieving successful results. Primary and secondary clinical success rates were 96.3% (52/54 patients) and 100% (2/2 patients), respectively. Conclusion: Percutaneous osteoid osteoma treatment with combination of radiofrequency and alcohol ablation is safe, effective, and minimally invasive with high primary and secondary success rates. Persistent or recurrent lesions can be effectively retreated. n 2007 The Royal College of Radiologists. Reprinted with permission.
