A large pheochromocytoma requiring aortic and inferior vena caval reconstruction: A case report

Resection of inferior vena cava, abdominal aorta, bilateral common iliac arteries, and bilateral partial external iliac arteries with artificial vessel replacement during radical endometrial cancer surgery: a case report

BACKGROUND

Endometrial carcinoma (EC) is a common malignant tumor of the female reproductive system, often accompanied by lymph node metastasis. Artificial vascular implantation is a common surgical treatment for mediastinal tumors and abdominal aortic aneurysms but is rarely used in gynecological surgery.

CASE PRESENTATION

A 54-year-old female patient was first admitted to the hospital in January 2018 due to "irregular vaginal bleeding over 3 months". CT showed a mass in the uterine cavity, and several swollen lymph nodes in the retroperitoneum and pelvic cavity. The initial diagnosis was an endometrial malignant tumor. We performed radical endometrial cancer surgery with parallel resection of inferior vena cava, abdominal aorta, bilateral common iliac arteries, bilateral external iliac arteries, and artificial vessel replacement, which was successful, with good postoperative recovery and no lesion progression at 3 years postoperative follow-up.

CONCLUSION

This is an early case of gynecological clinical use of prostheses. Through multidisciplinary cooperation, the surgical resection rate of patients with EC in radical surgery was improved without serious fatal complications and achieved a high long-term postoperative survival rate.

The good, the bad, and the ugly: uncommon CT appearances of pheochromocytoma

Pheochromocytoma is a neuroendocrine tumor arising in the adrenal medulla with varied imaging appearances and associated risk of serious cardiovascular complications if left undiagnosed and untreated. It is discovered incidentally in up to 70% of cases due to the increase in use of CT in clinical practice. Biopsy can have life-threatening consequences, so imaging is crucial for diagnosis and surgical planning. The purpose of this review is to demonstrate unusual CT appearances of pheochromocytoma and enhance diagnostic confidence in cases discovered incidentally. High level of suspicion for pheochromocytoma based on CT findings, along with urinary metanephrine levels, can obviate the need for additional expensive imaging.
