BACKGROUND The apparent paradox of natural history data suggesting low rupture risk of small asymptomatic aneurysms and the median size of aneurysm rupture remains unexplained. Aneurysm growth rates and their potential relationship with rupture risk have not been well examined in natural history studies. OBJECTIVE To examine the question of whether small asymptomatic aneurysms ≤ 7 mm that are...

We review some basic features of shear wave generation and energy balance for a 2D antiplane rupture. We first study the energy balance for a flat fault, and for a fault that contains a single localized kink. We determine an exact expression for the partition between strain energy flow released from the elastic medium surrounding the fault, radiated energy flow and energy release rate. This bal...

We report a 72-year-old female patient with spontaneous rupture of the left external iliac vein. She visited our hospital for abdominal and back pain. She had the abnormal finding of hemoperitoneum. We performed an emergency operation with diagnosis of left ovarian cyst rupture though she suffered from spontaneous rupture of the left external iliac vein. This case provides insight to the experi...

Historically, the treatment of splenic rupture has been splenectomy. With the emergence of splenic conservation in splenic trauma, similar concept has been applied to spontaneous rupture in other conditions. There are only few case reports of isolated splenic rupture in patients with hemophilia managed operatively with splenectomy [1,2]. Here, we describe the successful non-surgical management ...

Tendon rupture in SLE is a rare but potentially disabling complication. The etiology of tendon rupture is not well understood, but in some cases it is secondary to trauma and in others it is related to inflammatory changes in and around the tendon as a result of the underlying disease process. Corticosteroid therapy may also be responsible for tendon rupture in some patients. Therapy must be in...

There have been only sporadic reports of rupture of tendons in cases with lupus erythematosus (LE), e.g. rupture of the Achilles tendon (Cowan and Alexander, 1961; Lee, 1961; Bedi and Ellis, 1970) and rupture of the patellar tendon (Twining, Marcus, and Garey, 1964). We here present a case of spontaneous rupture of tendons in the hand of a male with LE. We were unable to find a similar report i...

Intracranial dermoid cysts are congenital tumors of ectodermal origin. Rupture of these cysts can occur spontaneously, but rupture in association with trauma is reported infrequently. The diagnosis of rupture is made by the presence of lipid (cholesterol) droplets in the subarachnoid spaces and ventricles. Nonenhanced CT of the head demonstrates multiple foci of low attenuation that correspond ...

Non-traumatic, spontaneous diaphragmatic rupture is a rare event whose pathophysiology is not known. We report the case of endometriosis-related spontaneous rupture of the right diaphragm with intrathoracic herniation of the liver, gallbladder and colon. We hypothesize that the invasiveness of endometriotic tissue caused diaphragm fragility, which finally lead to its complete rupture without tr...

Rupture of a gravid uterus is a surgical emergency. Predisposing factors include a scarred uterus. Spontaneous rupture of an unscarred uterus during pregnancy is a rare occurrence. We hereby present the case of a spontaneous complete uterine rupture at a gestational age of 34 weeks in a 35 year old patient. The case was managed at the University Teaching Hospital of Yaounde (Cameroon). She had ...
