Non-functional retroperitoneal paragangliomas are rare tumors. They are often asymptomatic and can reach very large sizes. We report the case of a 49-year old woman with retroperitoneal tumor detected during CT scan examination performed to find the cause of non-specific abdominal pain. Malignant forms, more frequent than benign forms, show locoregional invasion and are characterized by delayed-onset metastases. The treatment of these tumors is based on the most complete degree of surgical resection, since prognosis depends on it. There is no consensus on the usefulness of complementary therapies which may nevertheless constitute a supportive treatment.

Background And Aims: Cardiac ParaGangliomas (PGLs) are rare extra-adrenal tumours that arise from chromaffin cells of the sympathetic ganglia. PGL are often diagnosed incidentally, with no symptoms or symptoms related to cardiovascular dysfunction.
Methods: Cardiac Computed Tomography (CCT) and Cardiac Magnetic Resonance (CMR) can detect the correct morphology and position of the lesion and provide proper tissue characterization.

Paragangliomas are mostly benign, slow-growing, hypervascular tumors originating from neural crest derivatives. Head and neck (H&N) paragangliomas represent <1% of all H&N tumors and <5% are malignant. They are mostly non-secreting tumors that originate from autonomous parasympathetic paraganglia.

Background: Carotid body tumors (CBTs) are rare neuroendocrine neoplasms arising near the carotid bifurcation with a reported incidence of 1 to 2 cases in 100,000 patients. Most CBTs are sporadic, benign, slow-growing, and non-secreting, but untreated CBTs can grow locally to compress the nearby blood vessels, esophagus, and airway. Regional metastases can occur in 5% to 10% of cases, but distant metastases are exceedingly rare, occurring in roughly 1-2% of cases.

A 55-year-old woman presented with a 4-month history of right-sided non-specific loin pain and 6 kg weight loss. A CT scan of the abdomen and pelvis showed an incidental 4.5 cm right-sided adrenal lesion which was not typical of an adrenal adenoma.

Pheochromocytomas are tumors derived from chromaffin cells within the medulla of adrenal glands, whereas paragangliomas are tumors derived from extra-adrenal chromaffin cells of the sympathetic prevertebral and paravertebral ganglia. The growing deployment of genetic testing has shown that approximately 30% of pheochromocytoma and paraganglioma (PPGL) patients carry familial pathogenic germline mutations in known PPGL-susceptibility genes. This prompts genetic screening of their family members and leads to an increase in the detection of asymptomatic PPGLs or non-secreting tumors reported in familial cases discovered after the index patient work-up.
