Right Parapharyngeal Cavernous Hemangioma, A Rare Entity: Case Report and Literature Review

Abstract

Cavernous hemangioma is a noncancerous vascular growth that arises from different parts of the head and neck region. However, parapharyngeal space contributes a very small percentage for its occurrence. We present a case of right parapharyngeal cavernous hemangioma, a very rare clinical presentation. This is a 57-year-old female presented with throat discomfort for 3 months. Examination finding showed a soft, diffuse, and non-pulsating mass over the right upper jugulodigastric region. A contrasted computed topographic scan revealed multiple calcifications in right parapharyngeal space. T2-weighted magnetic resonance imaging showed right parapharyngeal space mass with high signal and multiple phleboliths and dynamic angiogram unremarkable. Surgical resection done via transcervical approach and histopathological report revealed cavernous hemangioma with calcified thrombi. In conclusion, surgical intervention is the mainstay treatment and transcervical approach which is adopted in this case is the commonest approach used in surgical resection of cavernous hemangioma.
