Hepatic hydatid cyst rupture and anaphylaxis after a fall.

A 15-year-old boy presented to the emergency unit complaining of dyspnea, urticaria and vomiting developed after he fell down when he was playing football. Abdominal ultrasound showed a ruptured hydatid cyst in the right lobe of the liver which was of communicating type. Echinococcus granulosus serologic tests were positive. Medical treatment was started immediately. One week later, follow up US showed no changes in the findings. Intrabdominal fluid leakage was not detected. Patient's general condition showed improvement and he was discharged 12 days later.

Ruptured hydatid cyst following minimal trauma and few signs on presentation.

Hydatid disease is a parasitic infection caused by Echinococcus granulosus characterised by cyst formation in any organ, although the liver is the most commonly involved. Hydatid cysts can rupture either spontaneously or following trauma. Surgical treatment can be life-saving. This paper reports the atypical presentation of a young girl admitted to the emergency department. She presented with pain on her palms due to falling down a few steps. Because of the rebound tenderness on the right upper quadrant of her abdomen on physical examination, bedside ultrasonography was performed to identify the underlying cause, and promptly revealed a 62 x 72 mm lobular cyst on the right lobe of the liver with free fluid in the subcapsular area. Shortly afterwards, urticaria developed. Fluid resuscitation, methylprednisolone and diphenylhydramine were administered intravenously. Afterwards she was taken to the operation room for unroofing, drainage and capitonage. In conclusion, primary care and emergency physicians should perform a complete physical examination on all admitted patients with vague symptoms and a high index of suspicion for a ruptured hydatid cyst, even following trivial trauma, especially in endemic regions.

Recurrent anaphylaxis due to non-ruptured hepatic hydatid cysts.

BACKGROUND: Hydatid disease, a parasitic infestation of humans, is endemic in the Mediterranean region, Australia, New Zealand and the Middle East, and mostly involves the liver. Anaphylactic reactions, which sometimes are the first manifestations of the disease, frequently occur due to cyst rupture after a minor/major trauma, though they may also be spontaneously seen on rare occasions. In extremely few studies, anaphylactic shock has been reported in patients without macroscopic rupture of the hydatid cysts. CASE REPORT: Our patient had recurrent anaphylactic episodes without any trauma and had been misdiagnosed for several years even though the patient was living in a region endemic for hydatid disease. CONCLUSION: We emphasize that physicians should be highly aware of hydatid disease as a possible etiology for seemingly idiopathic anaphylactic reactions, especially in endemic regions.

Taponamiento cardiaco por quiate hidatídico pericárdico / Cardiac tamponade caused by hydatid pericarditis

Presentamos el caso de una mujer sin antecedentes personales de interés que debuta con insuficiencia cardiaca con clínica de taponamiento cardiaco por pericarditis hidatídica secundaria a fistulización a traves del diafragma por rotura de quista hidatídico localizado en hígado. La hidatidosis cardiaca es poco frecuente presentado una incidencia según series entre el 0,2-2% sobre el total de infestación en humanos por Echinococcus, siendo la afectación pericárdica infrecuente. Es por ello que realizamos revisión de su etiopatogenia, presentación clínica, diagnósticos de elección y tratamientos recomendados

We present the case of a woman with no previous clinical history of disease, that debuted with acute heart failure with symptoms of cardiac tamponade from hydatic pericarditis as a result of a fistula across the diaphragm secondary to a hidatidic cyst rupture in the Uver. Cardiac hydatidosis is rare with an incidence in some series betweem 0.2-2% in humans infested with Echinococcus, affectation of the pericardia being rare. For this reason we present a revision of its pathogenesis, clinical presentation, diagnosis and recommended treatment
