Neuropathology reports among brain death cases following long intervals

Reference	Age	Interval	Neuropathology	Interpretation
Parisi, 1982 (10) (n = 1)	49 y	68 d	Transverse dural sinus thrombosis; cortical subpial vascularization and macrophages; “coagulative necrosis but … no evidence of cellular reactivity” of deeper structures	“Inward progression of the reparative response from the leptomeningeal surface, presumably originating from the intact extracranial circulation”
Ito, 1992 (36) (n = 1)	14 y	101 d	“Proliferation of vessels and fibrosis…[and] erythrocytes, leucocytes and scavenger cells in the dura mater”	“Secondary petechial haemorrhage…appear to occur long after the trauma, in spite of the complete cessation of cerebral blood flow … [and] may be produced from newly formed vessels in the dura mater by secondary circulatory disturbances” … [since] the blood flow of the dura is maintained by the middle meningeal artery which originates from the external carotid artery
Repertinger, 2006 (11) (n = 1)	4 y	20 y	Calcified shell, with ossification and marrow, grumous mummified material, mineralized cell processes, iron pigment, extensive small focal calcifications	“blood flow was insufficient over the 2 decades for macrophages to arrive and remove most of the debris”
