RESUMO
We describe a previously unreported anatomical variant of the peroneal artery that was found both on preoperative angiography and at operation to be related to the fibula only in its distal third. In contrast to previously reported variations, the artery began descending on the medial aspect of the fibula about 26cm from the fibular head.

BACKGROUND: The prevalence of synchronous or metastatic tumors in patients with head and neck squamous cell carcinoma (HNSCC) ranges from 6% to 20% and has implications for prognosis and management of the primary disease. There is no consensus about the role of chest CT prior to definitive treatment patients with HNSCC. METHODS: A systematic review of all chest CT studies in relation to HNSCC was performed, together with a review of our local database. RESULTS: Twenty-four studies were identified in addition to our local data. Prevalence of positive chest CT was 7.93%. Patients were significantly more likely to have a positive chest CT with N2 or N3 neck disease (p = .0062) and stage III or IV disease (p = .0001), and significantly less likely with tumors of the oral cavity (p = .0007). CONCLUSION: We advocate chest CT as part of the initial investigations for patients with HNSCC.
