    Enhanced cervical MRI in identifying intracranial dural arteriovenous fistulae with spinal perimedullary venous drainage (1998)

    Notizen: Abstract Diagnosis of an intracranial dural arteriovenous fistula (DAVF) with spinal perimedullary venous drainage is challenging because the presenting symptoms are usually related to dysfunction of the spine, not of the brain. Repeated spinal angiograms are usually performed before the diagnosis is finally made by cerebral angiography. We report two cases of intracranial DAVFs with spinal perimedullary venous drainage. In both cases contrast-enhanced cervical MRI demonstrated dilated lower brainstem and upper spinal veins, which, we believe, is a good indicator of the existence of such drainage. We suggest that, in cases with perimedullary serpentine enhancement on thoracic or lumbar MR images, additional Gd-enhanced cervical spinal MR imaging should be performed. The simple process of tracing the veins upwards may avoid a lot of unnecessary examinations and delay in the diagnosis.

    Spontaneous spinal epidural haematomas with repeated remission and relapse (1997)

    Notizen: Abstract We present a case of spontaneous spinal epidural haematoma (SSEH) with a rare clinical course of repeated spontaneous recovery and relapse. The patient suffered three episodes of upper-back pain of sudden onset followed by sensory and motor dysfunction after weight lifting. In the first two episodes, the neurological deficits recovered spontaneously and completely. In the last episode, paraplegia persisted even after emergency surgery. Serial studies with computed tomographic (CT) myelography and magnetic resonance imaging (MRI) demonstrated the remitting and relapsing course of the SSEHs. The possible causes of the SSEHs and the mechanisms of spontaneous recovery are discussed.

    The MRI signs of spinal arachnoid diverticula (1997)
    Springer

    Thema: Medizin
    Notizen: Abstract Our goal was to find MRI signs of use for identifying a spinal arachnoid diverticulum. Three cases of spinal arachnoid diverticula, one extradural and two intradural, were examined on a 1.5 T imager. There was obvious mass effect on the adjacent structures in one case and increased signal intensity in the diverticulum on proton density- and T2-weighted images in two cases. Signal changes due to turbulent movement of the spinal fluid inside the diverticula were seen in all cases on sagittal fast spin-echo (FSE) proton density- and T2-weighted images; it was difficult to tell whether these signal changes imply a communication or are simply FSE artefacts. On contrast-enhanced studies, all cases showed partial enhancement inside the diverticula. There thus are four signs of diverticula: mass effect, the increased signal, signal void sign and partial enhancement; the last of these, the most reliable, has never been reported before.

    Balò's concentric sclerosis: MRI (1996)

    Notizen: Abstract We report a case of Balò's concentric sclerosis. In the past, the diagnosis was usually made post mortem. In this case, we found that CT demonstrated only low-density lesions, but not their concentric pattern. However, MRI showed a striking feature, reminiscent of histopathology of Balò's concentric sclerosis, and played an important role in antemortem diagnosis of this rare demyelinating disease.

    Central gadolinium enhancement of an acute spontaneous spinal epidural haematoma (1996)
    Springer

    Thema: Medizin
    Notizen: Abstract Spontaneous spinal epidural haematoma (SSEH) is uncommon, but central gadolinium (Gd) enhancement of the haematoma is even rarer. To our knowledge, only one case has been reported, but no explanation was given concerning the mechanism of this enhancement. We present a case of SSEH with unusual central Gd enhancement which we believe is due to oozing from the injured posterior internal venous plexuses. Therefore, although rare, central Gd enhancement of an epidural mass should not rule out the possibility of a haematoma.

    Intracranial meningeal melanocytoma: CT and MRI (1997)

    Thema: Medizin
    Notizen: Abstract We report the MRI and CT findings of an intracranial meningeal melanocytoma (IMM) arising from Meckel's cave and review the imaging characteristics of IMM. On CT, IMM constantly appear as well-circumscribed, isodense to slightly dense, extra-axial tumours with homogeneous contrast enhancement. This appearance is nonspecific and similar to that of meningiomas or small neuromas. On MRI, the signal of IMM is strongly related to the amount of melanin pigment: the more melanin, the more shortening of T1 and T2 relaxation times. Only when it shows as a homogeneous mass, bright on T1 and dark on T2 weighting, can a specific diagnosis of a melanin-containing tumour be made. However, this still cannot provide a distinction between IMM and malignant meningeal melanoma.
