Thoracic Extradural Paraganglioma Localized on 68Ga-DOTANOC PET/CT.

We present the case of a 33-year-old woman with complaints of headache and palpitations with raised urinary catecholamines. Ultrasound of the abdomen was noncontributory, and the patient was referred for 68Ga-DOTANOC PET/CT, which revealed tracer accumulation in the thecal sac/spinal canal at D5-D7 level, suggestive of a thoracic paraganglioma. MRI of the spine subsequently confirmed the presence of an extradural mass in the spinal canal extending from D4 to D8.
