1/91. myocardial infarction and death after caesarean section in a woman with protein s deficiency and undiagnosed phaeochromocytoma.We describe the case of a 36-year-old woman, with a previous history of recurrent abortion due to protein s deficiency, undergoing an elective Caesarean section at 39-weeks gestation. During pregnancy no signs of hypertension or cardiovascular disease were reported, but at the end of the surgical procedure, the patient developed acute hypertension, leading to myocardial infarction, severe heart failure and death. The autopsy revealed a 2-cm undiagnosed phaeochromocytoma in the right adrenal gland. Clinical diagnostic features of phaeochromocytoma during pregnancy as well as the main therapeutic approaches suggested in the literature are discussed.- - - - - - - - - - ranking = 1keywords = pregnancy, gestation (Clic here for more details about this article) |
2/91. pheochromocytoma and sub-clinical Cushing's syndrome during pregnancy: diagnosis, medical pre-treatment and cure by laparoscopic unilateral adrenalectomy.The coexistence of pheochromocytoma and primary adrenal Cushing's syndrome of the same adrenal gland has rarely been reported. We describe here the case of a female patient presenting with mild Cushing's stigmata, hypertension and diabetes mellitus in whom we diagnosed a pheochromocytoma of the left adrenal gland with coexisting non-ACTH-dependent cortisol hypersecretion. While hormonal work-up was still in progress, the patient became pregnant and wanted to carry her pregnancy to full-term. A laparoscopic adrenalectomy in the 17th week of gestation was decided upon and the patient accordingly prepared for surgery by pre-treatment with phenoxybenzamine. Successful surgery--the first ever reported laparoscopic resection of a pheochromocytoma in pregnancy--without perioperative complications was performed under general anesthesia, with the patient receiving peri- and post-operative hydrocortisone substitution. Pathohistological examination revealed a pheochromocytoma with positive immunostaining for interleukin-6 (IL-6) and negative immunostaining for ACTH, vasoactive intestinal polypeptide (VIP) and cytochrome P450, and with no signs of malignancy. A paracrine stimulation of the ipsilateral adrenal cortex by IL-6 produced by the pheochromocytoma, leading to cortical hyperplasia and subclinical Cushing's syndrome, is suggested by the positive immunostaining for IL-6 and the MRI findings. Post-operatively, secondary adrenal insufficiency ensued, necessitating continuing hydrocortisone replacement over 12 months. hypertension resolved after surgery, and diabetes after the uncomplicated vaginal delivery at term.- - - - - - - - - - ranking = 2.8109051231866keywords = pregnancy, gestation (Clic here for more details about this article) |
3/91. Diagnosis and management of pheochromocytoma during pregnancy: a case report.pheochromocytoma is known to increase morbidity and mortality. We describe a case of pheochromocytoma during pregnancy. A patient was transferred to our hospital during gestational week 15 with severe hypertension, acute pulmonary edema, and cardiomyopathy. One day after transfer, she had a spontaneous abortion of the fetus. One week after hospital transfer, she developed acute dyspnea, supraventricular tachycardia degenerating into ventricular tachycardia, and respiratory failure requiring mechanical ventilation. pheochromocytoma caused by a right adrenal mass was diagnosed. The patient was treated with titrated doses of phenoxybenzamine, intravenous nicardipine, and metyrosine over a period of 3 weeks with resultant stabilization of her blood pressure. She underwent a successful right adrenalectomy 1 month after her initial presentation. Four months after surgery, all antihypertensive medications were discontinued and her blood pressure remained stable 1 year after the surgery. This case describes the maternal morbidity and fetal mortality that may be associated with pheochromocytoma during pregnancy.- - - - - - - - - - ranking = 2.8109051231866keywords = pregnancy, gestation (Clic here for more details about this article) |
4/91. pheochromocytoma associated with pregnancy: case report and review of the literature.We report on a young woman with pheochromocytoma associated with pregnancy and review 41 other cases reported in the literature from 1988 to 1997. This review reveals that the overall maternal mortality was 4 percent and the fetal loss 11 percent; antenatal diagnosis of pheochromocytoma reduced maternal mortality to 2 percent; however, fetal loss was 14 percent. Diagnosis of pheochromocytoma was made antepartum in 83 percent of the cases. Although pheochromocytoma associated with pregnancy is rare, a high index of clinical suspicion must be kept and all those at risk must be investigated to achieve an early diagnosis and improved outcome. Once the diagnosis is confirmed, alpha-adrenergic blockade is essential and beta-blockade may be required. magnetic resonance imaging and computerized tomography scan may be used to localize the tumor during the antenatal period. In early pregnancy, i.e., before 24 weeks, both tumor resection and medical treatment are associated with good fetal outcome; in later pregnancy, elective cesarean delivery followed by tumor resection results in favorable maternal and fetal outcome. TARGET AUDIENCE: Obstetricians & Gynecologists, family physicians. learning OBJECTIVES: After completion of this article, the reader will be able to understand the clinical manifestations of a pheochromocytoma during pregnancy, how to make the diagnosis of a pheochromocytoma during pregnancy, and to know the medical and surgical management of a pheochromocytoma during pregnancy.- - - - - - - - - - ranking = 4.9799890887633keywords = pregnancy (Clic here for more details about this article) |
5/91. Massive bilateral phaeochromocytomas in association with Von Hippel Lindau syndrome in pregnancy.We report a rare case of large bilateral phaeochromocytomas in pregnancy, found coincidentally by ultrasonography at 26 weeks' gestation, in a woman with a family history of Von Hippel Lindau syndrome. Further, we report maternal and fetal serum and amniotic fluid phenoxybenzamine levels from this case.- - - - - - - - - - ranking = 2.35817884239keywords = pregnancy, gestation (Clic here for more details about this article) |
6/91. Phaeochromocytoma in pregnancy.The diagnosis of phaeochromocytoma during pregnancy requires a high index of suspicion and is essential for the favourable outcome of mother and offspring. delayed diagnosis is associated with considerable morbidity and mortality. The cases of 4 patients presenting with phaeochromocytoma during pregnancy over an 11-year period are presented.- - - - - - - - - - ranking = 2.71635768478keywords = pregnancy (Clic here for more details about this article) |
7/91. pheochromocytoma with negative urinalysis in pregnancy.We present a rare case of adrenal pheochromocytoma in pregnancy, with serial 24-h urine specimen collections showing normal concentrations of catecholamine metabolites. The diagnosis was based on clinical presentation, abdominal ultrasound, and magnetic resonance imaging, and was confirmed on post-operative pathohistological examination. Clinical suspicion of pheochromocytoma in pregnancy should be sufficient to implement adequate therapeutic measures, regardless of urine catecholamine concentrations.- - - - - - - - - - ranking = 2.71635768478keywords = pregnancy (Clic here for more details about this article) |
8/91. Acute heart failure in the parturient--do not forget phaeochromocytoma.Phaeochromocytoma is a rare condition and extremely rare in pregnancy. Diagnosis is notoriously difficult, as phaeochromocytoma may present a broad spectrum of clinical manifestations. The key to a successful outcome is a high index of suspicion of its existence and its early diagnosis.- - - - - - - - - - ranking = 0.45272628079666keywords = pregnancy (Clic here for more details about this article) |
9/91. Phaeochromocytoma diagnosed during labour.The diagnosis of phaeochromocytoma during pregnancy is rare.

10/91. pheochromocytoma of the heart.This is a presentation of a unique case of cardiac pheochromocytoma during pregnancy. The case is significant because pheochromocytoma is a difficult diagnosis and its rarity during pregnancy may lead to this important diagnosis being overlooked, even though treatment is specific and highly successful.- - - - - - - - - - ranking = 0.90545256159332keywords = pregnancy (Clic here for more details about this article) |
