The forensic significance of pseudomesotheliomatous adenocarcinoma of the lung
Abstract Pseudomesotheliomatous carcinomas (PMC) are rare tumors that clinically, macroscopically, and sometimes histologically resemble malignant pleural mesotheliomas. We report a case of a 91 year woman who was found to have diffuse nodular pleural thickening and a lung mass during a workup for persistent cough. She declined rapidly and died before a histologic diagnosis could be made. Postmortem examination revealed a tumor that diffusely involved the pleural surface with local...

Frequency of macroscopic intradural hemorrhage with and without subdural hemorrhage in early childhood autopsies
Abstract Some authors have suggested that in the fetus, neonate and infant, intradural hemorrhage (IDH) is relatively common and often presents alongside subdural hemorrhage (SDH). These authors have theorized that pediatric SDH may result from an IDH due to blood leakage from a dural vascular plexus. In this study, we report the inter-observer variation for detection of IDH from a retrospectively collected series of pediatric autopsy photographs, with and without SDH. Autopsy...

Fatal bilateral pneumothorax and generalized emphysema following contraindicated speaking-valve application
Abstract We report a case of a contraindicated attachment of a speaking valve to a tracheal tube with an inflated cuff, which rapidly resulted in the patient's death. The attached one-way valve allowed unrestrained inspiration through the tracheal tube but prevented physiological expiration. The increased pulmonary pressure resulted in alveolar rupture and replaced expiration with a steady release of air into the peribronchial sheaths and the mediastinum, resulting in what is commonly...

Detection of cellular material in lip-prints
Abstract We report on the visualization of cellular material within lip-prints using Diamond™ dye (DD). The transfer of cellular material via the lips can occur in cases of contact with food or drinking items as well as cases of alleged sexual assault involving oral contact. DD can effectively detect cellular material transferred by touch. Here we investigate if lip-prints can be detected and whether there is consistency within, or variability between, a person's propensity to...

Isolated condylar fractures diagnosed by post mortem computed tomography
Abstract Due to their anatomical location, occipital condylar fractures (OCFs) are usually not observed during traditional autopsies and are therefore considered a rare injury. The aim of this study was to determine the true frequency of OCFs using post-mortem computed tomography (PMCT) in traumatic casualties. We retrospectively analyzed 438 PMCT studies of victims of traffic accidents, falls from height, violence, and low-energy head injuries (324 males and 114 females). OCFs...

VirtoScan-on-Rails – an automated 3D imaging system for fast post-mortem whole-body surface documentation at autopsy tables
Abstract Two-dimensional photographic documentation is a substantial part of post-mortem examinations for legal investigations. Additional three-dimensional surface documentation has been shown to assist in the visualization of findings and contribute to the reconstruction of the sequence of events. However, 2D photo documentation and, especially, 3D surface documentation, are time-consuming procedures that require specially trained personnel. In this study a 3D imaging system,...

Post-mortem MRI-based volumetry of the hippocampus in forensic cases of decedents with severe mental illness
Abstract A decrease in the volume of the hippocampus is associated with severe mental illness, especially schizophrenia, and has been studied extensively in the living using magnetic resonance imaging. Autopsy cohorts also represent a valuable data source for imaging studies. However, post-mortem magnetic resonance imaging (PMMRI) is subject to unique challenges, such as the lower core temperature of scanned subjects and the influence of decomposition processes. This study aimed...

Melioidosis mimicking miliary tuberculosis
Abstract Melioidosis is an infectious disease caused by Burkholderia pseudomallei, a gram-negative intracellular bacillus. Tuberculosis, also an infectious disease, is caused by Mycobacterium tuberculosis, an acid fast bacillus. In both diseases, patients commonly present with fever and respiratory symptoms due to sepsis which might lead to respiratory failure or sudden death if left untreated. Not only are these two entities similar in clinical presentation, but the autopsy...

Lethal carbon monoxide toxicity in a concrete shower unit
Abstract A 47-year-old previously-well woman was found dead on the floor of a shower cubicle on a property in rural South Australia. The impression of the attending doctor and police was of collapse due to natural disease. Although there was significant stenosing coronary artery atherosclerosis found at autopsy, cherry pink discoloration of tissues prompted measurement of the blood carboxyhemoglobin level which was found to be 55%. The source of the gas was a poorly-maintained...

The use of gasoline in a complex suicide
Abstract This case represents a planned complex suicide in which the victim shot himself in the head after dousing his living quarters with gasoline. The spark induced ignition of gasoline vapors and led to an explosion. Liquid gasoline is not flammable, but the vapor/mixture of gases above the surface of the liquid is. In this case the victim might have counted on the resulting fire and/or explosion, but we are not able to tell that with certainty. We have assumed that the plan...

Fatal subarachnoid hemorrhage caused by rupture of variant anterior communicating artery: a case report and literature review
Abstract Fatal subarachnoid hemorrhage (SAH) caused by anterior communicating artery (ACoA) rupture is a rare event in medicolegal practice. Anatomical variations of the ACoA tend to make its anatomical structure, and as a result, blood flow through it, more complicated, which may increase hemodynamic stress and cause weak spots in the affected blood vessels. Variant ACoAs are prone to rupture in the event of a blunt-force trauma. Here, we report a fatal case of SAH caused by...

Sodium nitrite food poisoning in one family
Abstract Sodium nitrite is used as a coloring agent or preservative in food, as well as an antimicrobial agent in meat and fish and some cheeses. In high amounts it can be toxic for humans, causing methemoglobinemia. This is an unusual and potentially fatal condition in which hemoglobin is oxidized to methemoglobin (MHb), reducing the amount of oxygen that is released from hemoglobin, similar to carbon monoxide poisoning. MHb levels of 70% are generally lethal, but the existence...
