In another study, Heston (1953) fonnd that snbcntaneous injections of HD (0.05 cc of a 0.05% solution at weekly intervals for 6 weeks, or 0.1 cc of a 0.1% solntion in olive oil at 2-day intervals for a total of 6 doses) into the mid-dorsal region of mice (strains A, C3H, and C3Hf) resulted in injection-site tumors, whereas injections of vehicle alone did not indnce tnmor formation. Tumors occurring at the injection site included sarcomas, sarcomas neurogenic in origin, a rhabdomyosarcoma, papillomas, a squamous cell carcinoma, a hemangioendothelioma, and a mammary carcinoma.

Extracranial meningiomas are very rare (1%). In some cases they may be located in the parapharyngeal space even though most of the tumors within this location are benign salivary grand tumors or neurogenic tumors like schwannomas.

A variety of solid and cystic masses can be encountered around the knee as incidental findings. Most are benign, have an indolent behavior, such as lipomas, synovial and ganglion cysts, bursitis and neurogenic tumors, and can be easily diagnosed with US based on previously described criteria (Fig. 12.135). In the knee, however, there are some specific masses which merit particular attention. These include the lipoma arborescens and pigmented villonodular synovitis. In addition, an accessory muscle, the tensor fasciae suralis, can present as a pseudomass arising on the posterior aspect of the knee and warrants additional brief discussion here. 

Soft-tissue masses in the ankle are uncommon (OzDEMiR et al. 1997). They may he asymptomatic or may cause disturbances, such as pain, weakness, swelling, joint impairment or tarsal tunnel syndrome. With US, the diagnosis of a solid or complex mass versus a cystic mass can reliably be performed in the soft tissue of the ankle. The US characteristics of many masses that arise around the ankle joint are reported in the General Section of this book. However, the specific features of some of them, including ganglia, neurogenic tumors and abscesses, warrant additional brief discussion here. Accessory muscles (peroneus quartus, flexor digitorumlongus accessorius, accessory soleus) have already been described in previous sections of this chapter.
