Autopsy verifies demyelination and lack of vascular damage in partially reversible radiation myelopathy.

Study Design: Case report of recovering radiation myelopathy.

Objective: To present autopsy and functional imaging findings on a unique case of slowly recovering radiation myelopathy with the aim of the clarification of the underlying mechanism.

Patient: The cervical spinal cord and the distal part of the medulla oblongata of a 36-year-old thyroid cancer patient had been incorrectly irradiated with a total dose of 61 Gy and a fraction size of 3.

[Immunohistochemical study of hepatitis B surface and core antigens in HBsAg seronegative and seropositive organ and tissue donors].
