Management of a Complex Case of a Recurrent Paraganglioma.

Paragangliomas are rare, slow-growing, hypervascular, catecholamine-secreting neuroendocrine tumors arising from the paraganglia. Paragangliomas are rarely found in the head and neck and are typically benign, presenting as a painless, slow-growing mass. Surgical extirpation in combination with long-term surveillance has been long regarded as the standard of care; however, the advances in imaging, radiation therapy, and embolization techniques have improved diagnostic and therapeutic modalities. We present a case of an 87-year-old female who had previously undergone resection of a paraganglioma in 1998, with no evidence of disease in 2002. Eighteen years later, the patient presented to the clinic with otogenic complaints. Imaging showed an expansive mass from the jugular foramen with bone destruction and opacification within the ear canal. The patient opted for observation. The patient eventually presented to the emergency room with neurologic manifestations. Imaging showed a cerebellar abscess prompting emergency drainage. Intraoperative cultures grew Prevotella loescheii and S. intermedius , and the patient was started on 6 weeks of IV antibiotic therapy. Debulking of the paraganglioma was performed followed several months by mastoid and ear canal obliteration; however, the patient experienced complications, including dehiscence of the external auditory canal and Clostridium difficile infection. The patient was eventually treated successfully, marked by a reduction in complaints, a return to baseline activities, and imaging showing no increase in tumor size.
