Hepatic abscesses after liver transplantation secondary to traumatic intrahepatic bile duct injuries in a cadaveric allograft donor.

We report the case of an ultimately successful liver transplant recipient whose post-transplant course was complicated by the early development of multiple abscesses in the graft. Post-transplant cholangiography identified multiple shear injuries to the second and third order intrahepatic bile ducts, originating from blunt trauma to the donor liver. Treatment was non-operative following recent reports of the successful management of intrahepatic bile duct injury in the stable trauma patient. This discussion adds to the limited literature available on the transplantation of injured donor livers, despite this being a relatively common practice. Further experience is needed in determining the appropriate criteria for the use of traumatized donor livers. Cholangiography carried out on the back table may help to determine if such injured livers are suitable for transplantation.

Pigmented villonodular synovitis.

Pigmented villonodular synovitis (PVNS) is a rare benign proliferative growth of the synovium of obscure aetiology with a wide spectrum of clinical presentations and imaging findings. The purpose of this review is to acquaint the reader with the spectrum of imaging features of PVNS using a variety of imaging techniques.

Are T1 weighted images helpful in MRI of cervical radiculopathy?

MRI in patients with cervical myelopathy or radiculopathy usually includes T(1) weighted (T(1)W) and T(2) weighted (T(2)W) images. We prospectively examined a hypothesis that T(2)W alone is sufficient to diagnose the cause of cervical myelopathy and radiculopathy and that the T(1)W sagittal images do not provide additional useful information. 30 patients presenting with a history of cervical radiculopathy with or without myelopathy were prospectively assessed by MRI. Those with a history suggestive of intrinsic primary cord disease or who had previously had surgery were excluded. Two neuroradiologists, blinded to the clinical information, separately viewed the sagittal and axial T(2)W images alone, and at a later time, the full set of T(1)W and T(2)W images. Image quality, location and severity of disease and confidence of diagnosis at each level were scored on 4- or 5-point scales. The T(1) sequences did not demonstrate any significant lesions not already seen on the T(2)W images alone. The T(1)W sequence may safely be omitted in patients with radiculopathy.
