Thorotrast-induced oro- and hypopharyngeal fibrosis with recurrent bleeding

Cervical Thorotrast granuloma: a review of the literature and a new treatment modality

Extravasation of thorium dioxide after transcervical carotid angiography has resulted in persistent open draining neck wounds. These difficult problems have remained a challenge for the treating head and neck surgeon. Neck dissection has been the mainstay of treatment in the past; however, this has been fraught with complications. The application of doxycycline sclerosis is described in the successful resolution of a large thorotrast granulomatous neck wound. A review of the literature and the management options of Thorotrast granulomas are discussed.

Thorotrast granuloma: an unexpected diagnosis

An example of a Thorotrast granuloma (thorotrastoma) occurred in the neck of a patient 44 years after a carotid angiogram in which Thorotrast was used as radiological contrast medium. The lesion had produced a "cold" abscess and the patient was undergoing treatment for retropharyngeal tuberculosis. Thorotrast leakage can produce unusual clinical symptoms and signs which are frequently misdiagnosed.
