A case of massive calcification of the myocardium is presented that was diagnosed by postmortem computed tomography (PMCT) and confirmed by conventional autopsy. There are two types of pathologic calcification, dystrophic and metastatic. Massive calcification of the myocardium is associated with variable clinical outcomes, including sudden unexpected death. A 53-year-old man was found after he collapsed beside a walkway. He was transferred to hospital and died approximately two months later. To investigate the cause of death, PMCT and conventional autopsy were performed, which revealed massive calcification of the myocardium, a very rare finding at autopsy...

We examined the possibility of inflicting serious injuries with sharp objects in an experimental setting by throwing four sharp objects from different distances and with different throwing techniques. Using an overarm-handle (OA/H), overarm-blade (OA/B), underarm-handle (UA/H), underarm-blade (UA/B) and thrust (T/H) throwing technique, 10 adults (sex ratio 1:1) threw a chef's knife, a skinning knife, a paring knife and office scissors from 4 m and 2 m distance at synthetic abdomen models made of 10% gelatin covered with synthetic skin...

Alexander Pearce was an Irish convict incarcerated on Sarah Island on the west coast of Van Diemen's Land (modern day Tasmania, Australia) in 1822, following his transportation to the colony from the United Kingdom for seven years in 1819. On two occasions he escaped from the island, in September 1822 and again in November 1823, and was only able to survive the harsh conditions by killing and consuming his fellow escapees. Given that Pearce utilized the only sustenance that was at hand (i.e. his five companions), and that there was a temporal separation between the two episodes, this may represent a separate category of anthropophagy, that of serial opportunistic cannibalism...

Driver fatalities in motor vehicle collisions (MVCs) encompass accidents, suicides, and natural deaths when driving. The objective of this study was to determine the significance of pathology and other autopsy findings for drivers in fatal MVCs. Forensic autopsy records of driver fatalities in southeast Norway between 2000 and 2014 were studied retrospectively. Data from individual police and collision investigation reports were also collected and analyzed. In 406 driver fatalities, the male/female ratio was 340/66; 9% died from natural causes, 9% were suicides, 65% were culpable accidental deaths, 14% were nonculpable deaths, and 3% were undetermined deaths...

Decapitation is an occurrence only rarely encountered in forensic medical practice. This fatality is generally most often described in pedestrians who have been run over by trains accidently or in cases of suicide, or alternatively in occupants of cars involved in high speed vehicle collisions. We report, for the first time, a case of a complete decapitation of a pedestrian as a consequence of a traffic accident. Due to a thorough medico-legal investigation of the body and the involved vehicle, we were able to reconstruct the unique dynamics of the accident and the mechanism of injury...

Central pontine myelinolysis (CPM) is a neurological demyelinating disease of the pons. Although usually associated with rapid correction of hyponatremia, CPM may occur despite normonatremia, is often associated with chronic alcoholism and may be asymptomatic. Histological confirmation of asymptomatic CPM is rare. We describe an unusual post-mortem case of extensive but asymptomatic CPM in a chronic alcoholic patient with normonatremia. The affected part of the pons contained thinly myelinated axons with appearances supporting remyelination...

Ben Hall was a nineteenth-century Australian bushranger (outlaw) who was shot and killed by colonial police on May 5 1865. Popular belief is that Hall was shot while sleeping in his camp bedding. This contrasts with the official police version of Hall being shot while attempting to escape by running away. To evaluate this divergence of opinion a study of the gun belt allegedly worn by Hall at the time of his fatal shooting was undertaken. This revealed a nineteenth-century belt with a defect corresponding to an oblique bullet hole...

A gunfight between police and a gang of men led by the self-styled "Captain Moonlite", a.k.a. George Scott, occurred on 16th November 1879 at a farmhouse near Wantabadgery Station in the colony of New South Wales. The skirmish resulted in the deaths of two bushrangers and one police officer. As a result, Captain Moonlite and Thomas Rogan were hung in Sydney's Darlinghurst Gaol on 20 January 1880 for the murder of Constable Edward Webb-Bowen. Culpability for firing the fatal shot, however, has remained a source of controversy...

Malignant hyperthermia (MH) is an autosomal dominant disorder characterized by abnormal calcium homeostasis in skeletal muscles in response to triggering agents. Autopsy, morphology, and genetic analysis were performed on a 19-year-old man who died rapidly after exposure to sevoflurane during maxillofacial surgery. Muscle spasm around the operation area and limb rigidity occurred and renal tubules full of myoglobin casts were observed by microscopy. Ultrastructural changes in the skeletal muscles and the myocardium were detected by transmission electron microscopy (TEM)...

Epicardial adipose tissue (EAT) may play a role in the development of coronary artery disease. The purpose of this study was to evaluate a method based on postmortem computed tomography (PMCT) for the estimation of EAT volume. We PMCT-scanned the eviscerated hearts of 144 deceased individuals, who underwent a medicolegal autopsy. Using Mimics® we performed segmentation of the images and obtained the volumes of EAT and myocardium. Total heart volume was calculated by adding the volumes of EAT and myocardium...

We report the sudden death of a woman with neurofibromatosis type 1 (NF1). The decedent developed acute respiratory distress and died rapidly despite an emergent cricothyroidotomy. An autopsy with postmortem CT scan was performed to determine the cause of the fatal respiratory collapse and to determine if death was related to neurofibromatosis. Postmortem examination revealed the classical external hallmarks of neurofibromatosis, including innumerable cutaneous neurofibromas. In addition, there was a massive retropharyngeal hematoma with fatal extrinsic compression of the airway...

Acute subclavian artery dissection (SAD) is a rare entity which is usually associated with several vascular abnormalities and traumatic events. Spontaneous SAD remains exceptional and often affects the left artery. We report the autopsy case of a 29-year-old female who died suddenly following a spontaneous dissection of the right subclavian artery.

Pneumopericardium (PPC) and Tension Pneumopericardium (TPPC) refer to collections of gas in the pericardial cavity, the latter resulting in air tamponade and cardiac compromise. Following penetrating chest injuries, PPC and TPPC appear to be uncommon findings associated with a high mortality and correlated with other thoracic trauma. Diagnosis of PPC and TPPC is difficult relying on conventional autopsy alone, while postmortem computed tomography (PMCT) shows a high sensitivity for the detection of internal gas collections...

Animal feeding, both ante- and post-mortem, in freshwater and marine environments, has become topical recently. This report documents post-mortem scavenging by two identified species of marine crustaceans (Crustacea: Isopoda: Cirolanidae) on a human cadaver from the vicinity of Darwin, Northern Territory, Australia.

Although myocarditis is caused by viral infections in about 50% of cases in European countries, various other causative agents are known. We report the case of a 51-year-old man who died several months after being diagnosed with asthma by his general practitioner. This diagnosis had been confirmed by a pulmonologist approximately 6 weeks before the man's death. To rule out the possibility of medical malpractice the prosecuting authority ordered a forensic autopsy. At autopsy macroscopic indicators for perimyocarditis and pneumonia were found...

In May 2016, thirteen dogs housed in backyards within a single neighborhood were reported to have developed convulsions and died within a 24 h period. An investigation of the scene by law enforcement resulted in submission of eight dogs for postmortem examination. It was suspected that a rapid acting toxin was the cause of death. A gas chromatography-mass spectrophotometry (GC-MS) protocol combined with thin-layer chromatography that allows screening for common convulsants failed to identify a toxin in either pooled gastric content or liver samples from select cases...
