Bilateral glomus tumor treated with PET-CT based conformal radiotherapy: a case report
نویسندگان
چکیده
INTRODUCTION Glomus tumors are benign, slow growing tumors originating from paraganglionic tissue, mostly located at the carotid bifurcation, jugular foramen, cervical portion vagus nerve, and middle ear cavity. Radiotherapy is treatment of choice for patients with intracranial extension, and patients with bilateral and multiple tumors, or patients who are inoperable. CASE PRESENTATION We present a 53-year-old female patient with a glomus tumor treated with positron emission tomography computed tomography planning and 3D conformal radiotherapy, and the patient has remained free of disease progression 2 years after. CONCLUSION It is suggested that radiotherapy is a good treatment modality in patients with glomus tumor, and metabolic imaging and treatment planning with positron emission tomography computed tomography is superior to other imaging modalities.

Introduction: Modern radiotherapy (RT) techniques allow a highly precise deposition of the radiation dose in tumor. So, high conformal tumor doses can be reached while sparing critical organs at risk. Materials and Methods: This study was conducted in three phases. In the first phase; Fourteen patients with primary or recurrent prostate cancer receive Gallium-...

Introduction: Prostate-specific membrane antigen (PSMA) has been demonstrated as a promising tool for specific imaging of prostate cancer (PCa) via positron emission tomography-computed tomography (PET/CT) scanning. Radiation treatment planning (RTP) based on 68Ga-PSMA PET/CT scanning can also lead to some decision modifications. The specific goal o...

متن کاملMultidisciplinary approach in the treatment of malignant paraganglioma of the glomus vagale: a case report.
Malignant paraganglioma of the glomus vagale is a rare tumor entity originating from paraganglia or glomus cells. It typically affects middle age. It differs from benign paraganglioma because of its rapid growth and more aggressive clinical behavior. We report the case of a 40-year-old man presenting with a 5 cm lesion in the upper right cervical region detected by computed tomography (CT) and ...

Background: Inflammatory myofibroblastic tumor (IMT) is a tumor composed of myofibroblasts and a mixed inflammatory infiltrate that rarely undergoes malignant transformation. The most common sites of involvement include the lung, liver and orbit, but it has been reported to occur in nearly every site of the body, including oral cavity and soft tissue. Although common in other sites, such a tumo...
