Management of pheochromocytoma during pregnancy from diagnosis to laparoscopic adrenalectomy. A case report and review of literature

INTRODUCTION: Pheochromocytoma is an endocrine tumour of chromaffin cells. It can be diagnosed either sporadically or in the context of hereditary syndromes (e.g. Von Hippel Lindau, Neurofibromatosis type 1 and multiple neuroendocrine neoplasia type 2). During pregnancy, its frequency is very low (about 0,007%). This tumour causes paroxysmal hypertension in 0,1-0,6% pregnant women, because of an overproduction of catecholamines. If undiagnosed and nontreated, it's associated with high maternal and fetal mortality (40-50%). We report the case of a 30-year-old female diagnosed with pheochromocytoma during pregnancy at week 31 of gestation. In a multidisciplinary team made of surgeons, gynaecologists, anaesthetists, geneticists and endocrinologists we evaluated the case and according to literature, we choose a surgical approach after childbirth: performing a laparoscopic right adrenalectomy. DISCUSSION: In pregnancy, pheochromocytoma is a rare clinical condition. Gold standard treatment is laparoscopic adrenalectomy. However, the optimum timing of surgery is a challenge. CONCLUSION: Timely diagnosis of pheochromocytoma in pregnant women with hypertension and appropriate therapeutic management can lead to improve maternal, fetal and neonatal outcomes. The multidisciplinary team is necessary to recognize the symptoms and to adopt the right pre - and post - operative treatment. Laparoscopic adrenalectomy after delivery is safe and feasible even though the surgical procedure should be performed by an experienced surgeon.

Laparoscopic left nephro-adrenalectomy for renal vein leiomyosarcoma using (ICG) fluorescence and 3D-CT reconstruction: A case report

Introduction: Leiomyosarcoma is a rare malignant mesenchymal cancer of smooth muscle and about 50-60 % of cases are from inferior vena cava. Recently, preoperative reconstruction of three-dimensional (3D) images from computed tomography (CT) and intraoperative indocyanine green (ICG) are being developed. We present a case of laparoscopic left nephro-adrenalectomy using ICG fluorescence associated with 3D-CT reconstruction:n. Case report: A 72-years-old female patient presented pain in left side from two months. Contrast computed tomography and magnetic resonance imaging showed a solid mass between left-adrenal gland and upper renal pole. After multidisciplinary evaluation, a laparoscopic left nephno-adrenalectomy was performed. Discussion: The surgery was without intra and postoperative complications. The patient was discharged in the 3rd postoperative day without complications and with oral steroid replacement therapy. Histology confirmed leiomysarcoma of renal vein. Conclusion: In this case, use intraoperative ICG fluorescence associated with preoperative 3D-CT was a valuable support for surgery.
