Liver and spleen MRI findings in virus-associated hemophagocytic syndrome in a patient with acute lymphocytic leukemia.

Virus-associated hemophagocytic syndrome is characterized by the phagocytosis of erthythrocytes and other blood elements in multiple organ systems, especially the liver and spleen. Magnetic resonance imaging (MRI) can suggest this diagnosis in the proper clinical setting by demonstrating multiple, rounded signal voids in the spleen corresponding to hemosiderin deposition. We report a patient with virus-associated hemophagocytic syndrome during the course of acute lymphocytic leukemia and MRI findings that suggested the preoperative diagnosis.

Computed tomography of the normal and abnormal superior sagittal sinus.

The appearances on computed tomography (CT) of the normal and abnormal superior sagittal sinuses are presented. The varied patterns of non-enhanced and enhanced normal superior sagittal sinuses are correlated with and reflect the findings of anatomical dissection. Cases of abnormal superior sagittal sinus include thrombosis, brain death and sinus displacement.

Computed tomography in facial trauma.

Computed tomography (CT), plain radiography, and conventional tomography were performed on 30 patients with facial trauma. CT demonstrated bone and soft-tissue involvement. In all cases, CT was superior to tomography in the assessment of facial injury. It is suggested that CT follow plain radiography in the evaluation of facial trauma.

Computed tomography of colloid cysts of the third ventricle.

Ten cases of colloid cysts of the third ventricle were evaluated by computed tomography (CT). The smallest lesion demonstrated was 6 mm in diameter and the largest 6.5 cm. Six lesions were hyperdense and four isodense. None of the lesions exhibited significant enhancement after the administration of contrast medium. A non-contrast CT scan is essential for the demonstration of a small hyperdense colloid cyst as the latter may simulate normal vascular structures on the post-contrast scan.

CT of cerebral hemiatrophy.

Computed tomography (CT) findings in 10 cases of cerebral hemiatrophy are described. The CT appearance is typical and reflects the pathologic changes of unilateral loss of brain substance and calvarial thickening. In four patients with a mild form of the disease, a correct analysis of the pain skull radiographs was made only in retrospect. CT was found superior to plain skull films in the demonstration of subtle calvarial thickening and changes affecting the base of the skull.

Computed tomography in carotid cavernous fistula.

Two cases of carotid artery-cavernous sinus fistula of traumatic origin are presented. The diagnosis was suspected on computed tomography (CT) and confirmed by cerebral angiography. The CT findings included proptosis, a prominent superior ophthalmic vein, and marked enhancement of the cavernous sinus on the postcontrast CT scan.

Computed tomography of isodense subdural hematomas.

Eight cases of isodense subdural hematomas were evaluated by computed tomography (CT). CT demonstrated varying degrees of compression of a lateral ventricle, shift of the midline structures and, in some cases, obliteration of the subarachnoid sulci on the side of the lesion. Contrast enhancement was helpful in one case and demonstrated medial displacement of enhanced cortical margins away from the inner table of the skull. Two of the eight patients had no clear history of trauma.

Acute hemiplegia in children complicating upper respiratory infections. Report of three cases with angiographic findings.

Three children presented with acute onset of hemiplegia following an upper respiratory infection. Angiography revealed irregulaities, beading, and slow flow of a peripheral branch of a middle cerebral artery. In addition, one child had narrowing of the cervical segment of the internal carotid artery. An inflammatory arteritis of the cervical internal carotid artery is presumably the site of the formation of cerebral emboli.
