Segmental arterial mediolysis leading to spontaneous rupture of splenic artery and fatal hemorrhage in pregnancy.

We report an unexpected death of a 22-year-old primigravida who was admitted to the hospital with sudden abdominal pain two days before a scheduled delivery. During an emergency caesarean section due to intrauterine asphyxia, intraabdominal bleeding was observed with no apparent source of bleeding. Newly formed blood clots in the subdiaphragmatic space and arterial bleeding near the splenic hilum required a surgery on the next day. Hemorrhagic shock led to multiple organ failure on the fourth day of admission. The autopsy revealed ruptured splenic artery at the pancreatic tail and near the splenic hilum. Microscopically, different stages of segmental arterial mediolysis were observed in partially thinned and aneurysmatic artery.

Cor Triatriatum Dexter Associated with an Ostium Primum Atrial Defect and Left-Sided Opening of the Coronary Sinus in a Stillborn Fetus.

Cor triatriatum is a very rare cardiac malformation characterized by the presence of an abnormal interatrial membrane separating either the left or right atrial chamber into two compartments. It can be associated with other cardiac defects and is often symptomatic in childhood. The signs depend on the size and position of the interatrial membrane and other associated malformations. Here we report a case of right-sided cor triatriatum associated with an ostium primum-type interatrial septum defect and left-sided opening of the coronary sinus in a fetus. The cause of intrauterine death was asphyxia due to total placental abruption.

Suicide by sharp force associated with major self-mutilation and self-cannibalism.

Self-stabbing and self-cutting represents an uncommon method of suicide. We present a case of a 30-year-old man who was found dead in the forest. The body was naked and showed multiple cut and stab wounds on different parts of the body (face, neck, chest, abdomen, and extremities). A single-edged kitchen knife was found approximately 20 m from the body. Parts of both ears, the fifth toe of the right foot, and the scrotum were cut off. At the autopsy, two of the severed body parts-the toe and the part of the left ear-were found in the stomach. The cause of death was asphyxiation due to blood aspiration resulting from a cut throat injury. A police investigation uncovered a history of substance abuse and two previous suicidal attempts using a knife. Upon complex analysis of all the evidence, the manner of death was ruled a suicide, which was preceded by actions of major self-mutilation and self-cannibalism, both considered rare behavioral patterns.

Ventricular fibrillation and arrhythmia associated with cardiac fibromas involving both ventricles in a 1.5-year-old girl.

This article reports the autopsy findings of a 1.5-year-old girl with no history of previous hospital admission who suddenly collapsed at home. After 45 minutes of resuscitation efforts, the cardiac activity was restored. During hospitalization, she had ventricular arrhythmia and extremely elevated cardiac troponin levels. Internal examination and immunohistochemistry revealed cardiac fibromas of the right and left ventricles and extensive hypoxic myocardial damage. The right ventricular fibroma demonstrated interdigitating and entrapped myocardium visible at the edges and within the central portion of the tumor. The left ventricular fibroma originated in the subepicardial region and propagated towards the endocardium.

Undiagnosed cryptococcal meningoencephalitis with extensive hypoxic-ischemic brain injury mimicking grade 3 diffuse axonal injury.

In this article, we report the autopsy findings of a 50-year-old immunocompetent woman, who was hospitalized with an altered state of consciousness. Examinations, including cerebrospinal fluid analysis, carried out during hospitalization failed to identify the infectious agent causing progressive loss of consciousness and quadriparesis. The patient died within 8 days of admission to the hospital. Post-mortem microscopic and culture examination revealed Cryptococcus species. Death was attributed to cryptococcal meningoencephalitis. Histologic examination revealed accumulation of cryptococcus mimicking erythrocytes and extensive hemorrhage in hematoxylin and eosin-stained sections of the brain. Multifocal obliteration of the vascular bed by yeast was accompanied by hypoxic-ischemic brain injury mimicking traumatic diffuse axonal injury.

A Fatal Case of Cardiac Contusion After Blunt Chest Injury.

ABSTRACT: In this article, we report the autopsy findings of a 48-year-old man who sustained blunt trauma to the thorax. A medical record review revealed no history of cardiac disease. He presented to the hospital with a computed tomography-verified fracture of the left fourth and fifth ribs, and pulmonary and cardiac contusion. He was released from the hospital in stable condition at his own request 7 days later. Because of sudden deterioration, he was readmitted to the hospital the next day. Electrocardiogram detected cardiac arrhythmia on the 15th day after chest trauma. Electrocardiography detected pericardial effusion and severe mitral insufficiency resulting in left ventricular failure. Death was attributed to diffuse alveolar damage-complicating pneumonia due to cardiac contusion with mitral insufficiency occurring 25 days after hospital admission. Internal examination revealed diffuse fibrinous pericarditis, left atrial tear right above the anterior mitral valve leaflet with intrapericardial granulation tissue, and no sign of myocardial damage. Immunohistochemistry showed significantly more CD68-positive macrophages within tissue taken from the heart, a finding indicative of previous atrial and ventricular myocardial contusion. This case report demonstrates that routine hematoxylin and eosin staining may not always reveal significant myocardial damage.

Redistribution of acute traumatic infratentorial subdural hematoma to the spinal subdural space.

Spinal subdural hematoma is a rare and potentionally life-threatening condition associated with trauma and other pathological conditions. In this paper we report the autopsy findings of a 64 year old male who was repeatedly hospitalized with traumatic head injuries in the past. In this case spinal subdural hematoma was diagnosed post-mortem and later comfirmed by ante-mortem CT scan revaluation. Keywords: intracranial subdural hematoma - recurrent spinal subdural hematoma - diffuse axonal injury - autopsy findings.

Sudden Death Due to Cystic Tumor of the Atrioventricular Node and Fibromuscular Dysplasia Involving Branches of the Coronary Arteries.

In this paper, we report the autopsy findings of a 42-year-old White male who was found deceased at his home by his brother in the early morning hours with a history of excessive alcohol consumption 1 day before his death. A medical record review revealed chronic alcohol use with alcohol dependence syndrome, hypertension, and cardiac arrhythmias by electrocardiogram 2 years prior. External examination revealed only a single bruise on the forehead. Internal examination revealed changes associated with chronic alcohol abuse and mild atherosclerosis. The lack of a cause of death at autopsy resulted in a dissection of the cardiac conduction system and the detection of a small cystic lesion at the atrioventricular node region. Microscopic examination revealed a cystic tumor of the atrioventricular node and fibromuscular dysplasia of the coronary artery branches near the sinoatrial and atrioventricular nodes. Based on the case history and autopsy findings, death was attributed to a fatal cardiac arrhythmia due to cystic tumor of the atrioventricular node with fibromuscular dysplasia of the coronary artery branches near the sinoatrial and atrioventricular nodes a possible contributing factor.

[Unusual histopathological picture of acute lung injury in different stages of resorption with predominance of organizing pneumonia in a young man with influenza A (H1N1)]. / Neobvyklý histopatologický obraz akútneho poskodenia plúc v rôznej fáze rezorpcie s prevahou organizujúcej sa pneumónie u jedinca s chrípkou A(H1N1).

In this case report the authors describe histomorphological findings of acute lung injury with laboratory-confirmed influenza type A(H1N1) pneumonia leading to the death of a 30 year-old unvaccinated man after 27 days of hospitalisation. Histologically all three types of acute lung injuries were unusually present (diffuse alveolar damage, acute interstitial pneumonia, organizing pneumonia) in different phases of resorption and reparation with transition to extensive fibrosis.

Sudden death associated with syndromic craniosynostosis.

In this paper we report the autopsy findings of a 7 year old girl who presented with headache, nausea and repeated vomiting and died unexpectedly at home. She had no previous history of major illnesses and no history of epileptic seizures. External examination revealed ocular abnormalities. Internal examination demonstrated severe cerebral edema with tonsillar herniation, premature fusion of the cranial bone sutures, and prominent convolutional markings of the inner table of the skull. Death was due to severe cerebral edema complicating syndromic craniosynostosis. The craniofacial features in this case were in keeping with a diagnosis of Crouzon syndrome which was confirmed by molecular testing of the FGFR2 gene. Crouzon syndrome is a genetic disorder characterized by premature fusion of the cranial bone sutures resulting in distinctive malformations of the craniofacial region.

Sudden unexpected death due to severe pulmonary and cardiac sarcoidosis.

In this paper we report the autopsy findings of a 57 year old woman who died unexpectedly at home. She had been complaining of shortness of breath, episodes of dry coughing, and nausea. Her past medical and social history was unremarkable. She had no previous history of any viral or bacterial disease and no history of oncological disorders. Autopsy revealed multiple grayish-white nodular lesions in the pleura and epicardial fat and areas resembling fibrosis on the cut surface of the anterior and posterior wall of the left ventricle and interventricular septum. Histological examination of the lungs and heart revealed multiple well-formed noncaseating epithelioid cell granulomas with multinucleated giant cells. Death was attributed to myocardial ischemia due to vasculitis of intramural coronary artery branches associated with sarcoidosis. Sarcoidosis is a multisystemic disease of unknown etiology characterized by the formation of noncaseating epithelioid cell granulomas in the affected organs and tissues. The diagnosis of sarcoidosis in this case was established when other causes of granulomatous disease such as tuberculosis, berylliosis, hypersensitivity pneumonitis, and giant cell myocarditis had been reasonably excluded.

Unexpected fatal outcome of laparoscopic inguinal hernia repair.

In this paper we report the autopsy findings of a long-term warfarinized 60-year-old man who died unexpectedly 2 days after undergoing laparoscopic transabdominal pre-peritoneal (TAPP) inguinal hernia repair. In his medical records it was stated that the perioperative and postoperative period was uneventful with no sign of bleeding and he was discharged the day after surgery. Autopsy revealed massive bleeding in the pre-peritoneal space at the surgery site and a massive left inguinal canal hematoma spreading through the spermatic cord to the left scrotum. There was no evidence of retroperitoneal bleeding. No sign of traumatic injury to the abdominal wall, major abdominal and pelvic vessels was revealed. The cause of death was hemorrhagic shock. We believe that this is the first documented case of fatal outcome after TAPP inguinal hernia repair in Slovakia. Inguinal hernias account for approximately two-thirds of all abdominal wall hernias. The reported case demonstrates that routine procedures such as TAPP hernia repair can have a fatal outcome, not due to any surgical mishap but because of the altered health status of the patient.

[Traumatic pseudoaneurysm of descendent thoracic aorta solved by aortal stentgraft repair followed by development of fatal aortoesophageal fistula]. / Traumatická pseudoaneuryzma descendentnej torakálnej aorty riesená aortálnym stentgraftom s následnou fatálnou aortoezofageálnou fistulou.

Traumatic pseudoaneurysms are relatively frequently mentioned in textbooks of pathology and forensic medicine but their incidence in pathological reports is seldom documented. Our described case presented a patient who suffered from chronic alcoholism and who was repeatedly hospitalised because of various injuries including epidural and subdural hematomas. We present a case of a 69-year-old man who was hospitalised after nonspecific blunt chest injury with chest pain and dysphagia. By computed tomography the traumatic pseudoaneurysm of the descendent thoracic aorta was diagnosed pressing the oesophageal wall which was solved by implantation of aortal stent graft (TEVAR - thoracic endovascular aortic/aneurysm repair). Since after the implantation there was no blood leak, no progression of the lesion, he was soon discharged from hospital. The patient was hospitalised again after two months for newly developed haemoptysis. On suspicion of bleeding from aortal arch a carotid-carotid bypass from right to left side was performed and then re-TEVAR was implanted proximally to the first one. The man died two days following the implantation after a massive bleeding from oesophagus due to aortoesophageal fistula. The presented case deals with the etiology of the development of pseudoaneurysms, histomorphological picture of pseudoaneurysm resembling not only an isolated thoracic aortitis but slightly also the Takayashu disease. We suppose that in this case the most probable cause of necrosis and perforation of aortal wall was a decubital necrosis caused by stent graft which led to the fatal aortoesophageal necrosis. Aortoesophageal fistula belongs to the most common lethal complications of the TEVAR.

Truncus arteriosus communis with survival to the age of 46 years: case report.

Truncus arteriosus communis is an uncommon congenital cardiovascular malformation characterized by a single arterial trunk that arises from the base of the heart and gives rise to the coronary, pulmonary and systemic arteries. The prognosis in truncus arteriosus is very poor without surgical correction. The median age at death without surgery ranges from 2 weeks to 3 months, with 85 % mortality by age 1 year. The authors report the autopsy findings of a 46 year old man with truncus arteriosus communis without surgical intervention who died at the hospital shortly after admission.
