Acute subdural hematoma (SDH) occurs following severe head trauma with brain contusion or rupture of bridging veins. Conversely, SDH caused by rupture of a cortical artery without trauma or with minor trauma is also possible. Although over 150 cases of the latter SDH have been reported, they were predominantly diagnosed only during surgery, and therefore, no adequate histological evaluation has been performed. Therefore, essential etiology of this SDH type has remained unclear. In addition, the scarcity of autopsy cases may be attributed to arterial rupture being missed if the macroscopic findings are too minimal to detect during autopsy. Here, we describe two autopsy cases of SDH of cortical artery origin. Extravasation on postmortem computed tomography angiography and arterial leakage on macroscopic observation during autopsy facilitated detection of the ruptured artery and allowed detailed histological evaluation of the ruptured artery and adjacent dura mater. The etiology of arterial rupture is briefly described on the basis of histopathological findings in this study and the available literature.

An autopsy case of peliosis hepatis with X-linked myotubular myopathy.

Leg Med (Tokyo) 2019 May 18;38:77-82. Epub 2019 Apr 18.

This report describes the autopsy case of a 4-year-old boy who died from hepatic hemorrhage and rupture caused by peliosis hepatis with X-linked myotubular myopathy. Peliosis hepatis is characterized by multiple blood-filled cavities of various sizes in the liver, which occurs in chronic wasting disease or with the use of specific drugs. X-linked myotubular myopathy is one of the most serious types of congenital myopathies, in which an affected male infant typically presents with severe hypotonia and respiratory distress immediately after birth. Although each disorder is rare, 12 cases of pediatric peliosis hepatis associated with X-linked myotubular myopathy have been reported, including our case. Peliosis hepatis should be considered as a cause of hepatic hemorrhage despite its low incidence, and it requires adequate gross and histological investigation for correct diagnosis.
