Sudden death due to a massive hydatid pulmonary embolism secondary to a cardiac cyst rupture.

Cardiac echinococcosis is rare, and its clinical evolution is slow and asymptomatic until complications occur such as sudden death. Although more frequent in endemic countries, hydatid disease should be known by forensic specialists with regard to the migration flows of people from zones with high endemicity and who are likely to die from infection. We report an autopsy case of a 33-year-old male without any medical history who presented to the emergency room with shortness of breath, chest tightness, tingling all over the body and faintness without fever. He died suddenly before the medical examination. Autopsy showed no traumatic injuries or signs of violence. A cardiac 7 cm multivesicular hydatid cyst situated on the interventricular septum and the interatrial septum was observed. The cyst was ruptured with a massive hydatid pulmonary embolism. Hydatid cysts were also observed in the lungs. No signs of anaphylactic shock were found. The diagnosis of hydatid cyst was confirmed by histopathological examinations. Our case report highlights the mechanisms of occurrence of cardiac echinococcosis and hydatid pulmonary embolism as a complication, as well as the autopsy findings and the precautions needed by the forensic doctor.

Sudden death related to the gastrointestinal system in Tunisia: A 13 year autopsy study.

Sudden gastrointestinal (GI) death is an unexpected death due to digestive system causes mainly found after autopsy. The literature is rich in articles that studied sudden death due to cardiac causes while sudden GI deaths remain less well-documented. We retrospectively investigated all cases of gastrointestinal death at the Department of Forensic Medicine in Tunis, over 13 years (January 1, 2006 to December 31, 2018). Two hundred and eight cases were collected. The mean age of our series was 51.06 ± 20.99 years. No history of digestive disorders was reported in 78.4%, and no family history of sudden death was found in any cases. A male predominance was found in most epidemiological characteristics of the sample with a significant statistical rate in some features. Non-specific abdominal pain was the most described symptom (n = 92). Perforation of GI tract was the common mechanism involved in the death of 55 cases, of which 44 were related to ulcer perforation. These ulcer perforations were statistically more reported in smokers and people suffering from schizophrenia. Intestinal obstruction was the second commonest cause of death, mainly found in the elderly. Sudden death in children was most frequently caused by acute intussusception. This study highlights that systematic study of sudden death due to GI causes might provide opportunities to identify avenues for overall health improvement.

Unexpected fatal intramyocardial cartilaginous tumor: pathophysiology, mechanism of death and review of the literature.

Intramyocardial cartilage has never been reported in the human heart before. In the literature, the only reported localizations of cartilage in the heart were in the central fibrous body and the valves. We report a case of an unusual presence of cartilage tissue within the myocardial wall of the left ventricle in a 10-year-old boy who died unexpectedly. This case presents an interesting, unusual and apparently asymptomatic sudden cardiac death related to a cartilaginous myocardial tumor. Conducting system disturbance secondary to the myocardial tumor is the probable cause of death. This case is relevant not only for its singularity and originality, but also for the diverse and controversial hypotheses related to the onset of cartilaginous tissue in the myocardial wall. Early detection of this tumor by modern thoracic imaging may have prevented a fatal unexpected outcome.

Unusual suicides with band saws: two case reports and a literature review.

Suicides or suicide attempts with power saws (band, circular or chain saws) are rather rare events and only a few case reports exist in the forensic literature. The use of a band saw, in particular, has been extremely rare in cases of suicide. We report two cases of suicide that occurred in the same suburban area, three years apart. In each case, the victim was a carpenter and had a history of psychiatric disorder and/or of prior suicide attempts. We summarize the findings of the death scene investigations, the pertinent autopsy findings, and also summarize the world literature pertaining to suicide committed with power saws.
