RESUMO
Authors present a case of spontaneous rupture of internal iliac artery in common iliac venous, and propose a review of cases reported in literature. Abreast of modern imagery and especially computed tomography is able to give a precise diagnosis, but angiography is the Most accurate procedure for detecting arteriovenous fistula and cannot be excluded out of diagnostic approach.

The authors report a case of spontaneous rupture of spleen inaugurating the symptomatology of a pheochromocytoma. After presenting the observation, clinical problems are considered with a deceptive abdominal symptomatology and myocardial ischemia that could be part of an "adrenergic myocarditis"; the mechanism of ruptured spleen is analyzed. The diagnosis approach is discussed through a reliability study of various explorations: computed tomography has a sensitivity ranging from 93 to 97% which approaches 100% when associated with magnetic resonance, methyl-iodo-benzyl-guanidine scanning seems to be provided with similar reliability. During checking up for pheochromocytoma spreading, ectopic location was not found, but a cold thyroid nodule was detected which allowed suspecting a SIPPLE syndrome. The three-stage surgical approach was required by symptomatology, hemostasis splenectomy, lateral pheochromocytoma excision after a short preparation by blocking alpha and beta, and then total thyroidectomy after extemporaneous confirmation of the existence of a medullary carcinoma of the thyroid. This pathologic association leading to a SIPPLE syndrome is listed as part of the multiple endocrine neoplasias of type II (MEN II).
