AI Article Synopsis

  • A 10-year-old French bulldog was diagnosed with a large retroperitoneal mass after an MRI was performed to investigate pain and reluctance to move, which was initially suspected to be from a herniated disc.
  • The mass, identified as a retroperitoneal paraganglioma, caused compression of the dog's caudal vena cava and required surgical removal, along with a nephrectomy due to complications during surgery.
  • Post-surgery, the dog recovered well, and the study highlights that paragangliomas are under-researched in veterinary medicine, suggesting that future cases will enhance understanding and treatment of this tumor type.

Article Abstract

This article reports a case of a 10-year-old French bulldog initially seen for reluctance to move and episodes of pain. A magnetic resonance imaging study was undertaken in order to rule out a herniated disc. A large, retroperitoneal mass was visualized and cytological analysis suggested a neoplastic proliferation. The mass appeared to compress the caudal vena cava when viewed by abdominal CT scan. The mass was surgically removed. A nephrectomy was also carried out and aortic bleeding identified after dissection of adhesions. Despite these complications, the dog did well after the procedures. Postoperative checkups were normal. Histological and immunohistochemical analyses of the mass were compatible with a retroperitoneal paraganglioma. Key clinical message: This type of tumor is poorly described in the veterinary literature. As the behavior of this tumor type is not yet fully understood, each new description adds to our knowledge and should help in diagnosing and treating it more effectively in the future.

Paraganglioma, a catecholamine-producing tumor originating in extra-adrenal paraganglion cells, is rare in children. Although diagnosis of paraganglioma is based on the presence of catecholamine symptoms, some patients lack such symptoms. Delayed diagnosis is associated with tumor growth and invasion of surrounding vessels.

Durable and deep response to CVD chemotherapy in SDHB-mutated metastatic paraganglioma: case report.

Introduction: Succinate dehydrogenase subunit B (SDHB)-mutated paragangliomas (PGLs) are rare neuroendocrine tumors characterized by increased malignancy, readily metastasizing, and poorer prognosis. Here we report a case of SDHB-mutated metastatic PGL, wherein the patient showed significant tumor shrinkage and complete symptom remission following chemotherapy. We aim to contribute additional evidence to the existing knowledge associated with SDHB-mutated PGLs.

Paragangliomas originating from blood vessels are exceptionally rare, presenting diagnostic challenges due to their histological resemblance to other vascular neoplasms. We present a case study of a 60-year-old woman with underlying hypertension and dyslipidemia with obesity, initially diagnosed with angiosarcoma based on imaging and histological characteristics viewed via CT-guided biopsy. Intraoperative exploration revealed a lobulated tumor located between the inferior vena cava (IVC) and aorta measuring 7 cm × 8 cm, during which the patient developed transient hemodynamic instabilities.

Extra-adrenal, functional paraganglioma, if not medically controlled, requires early surgical resection. This can often be challenging when found in a retroperitoneal location, where resections are prone to lymphatic disruption and chyle leaks. Chylous ascites carry a significant risk of protein and caloric malnutrition, dehydration, and even mortality given the nutrient-rich characteristic of lost lymphatic fluid.

Pheochromocytoma and paraganglioma are often associated with hereditary syndromes, particularly those involving genes such as , which is linked to multiple endocrine neoplasia type 2A. Genetic testing plays a crucial role in diagnosing these conditions, guiding treatment strategies, and providing early intervention options for the affected families. A 57-year-old man presenting with back pain was found to have a left adrenal tumor and a retroperitoneal tumor near the left renal hilum.
