Evaluation of collateral flow capacity in patients with vascular or tumorous lesions of the skull base by Doppler sonography

1991

In 12 patients with vascular or tumorous lesions of the skull base, the collateral flow capacity was examined by transcranial Doppler sonography and carotid compression studies. In four patients no cross flow mechanism was found, in two patients the test remained unclear, and in six patients the examination suggested a good collateral flow capacity. However, for this application of Doppler sonography no borderlines have yet been defined and thus interpretation is difficult. Intraoperative Doppler sonography was used in five patients and proved to be helpful for localisation of the internal carotid artery within skull base tumors.

Microsurgical treatment of midfacial tumours involving the skull base

1998

Various approaches to the base of the skull for the treatment of cranial base tumours are described in detail. Advantages and disadvantages of the particular approaches are discussed. This clinical experience is based on 303 neoplasms involving the base of the skull, operated on by the authors. Retrospective survival studies are presented and a review of the literature on the subject is discussed. Utilizing microsurgical techniques the 2-, 3- and 5-year survival rates were significantly improved. The functional and aesthetic outcomes were also dramatically superior compared with standard ablative procedures. Reconstructive postoperative strategies are suggested.

Value and limits of computer-assisted tomography.

1980

Three years ago, at the VIIth International Congress of Radiology in Otorhinolaryngology, held in Copenhagen, the early impressive results of computer-assisted tomography (CAT) in otorhinolaryngology were presented. Since considerable technologic and diagnostic progress of CAT has taken place in the meantime, questions about the increase in CAT's value and the expansion of its limits are appropriate now. Computed and, in some cases, conventional tomograms of facial lesions are used in the discussion of these questions. There is no doubt of CAT's advance within the last few years; there are, however, limits of CAT to be emphasized: (a) coronal CAT might be uncomfortable (especially if the ga…

A rare case of solitary brain Langerhans cell histiocytosis with intratumoral hemorrhage in a patient affected by Turner syndrome

2016

Background: Langerhans cell histiocytosis (LCH) is a rare disease involving clonal proliferation of cells with characteristics similar to bone marrow-derived Langerhans cells. The case of a young woman, affected by Turner syndrome and a solitary intraparenchymal LCH associated with an osteolytic lesion of the overlying skull, is presented. Case Description: The patient, with an insidious history of headache and a growing soft mass in the left frontal region, presented with a sudden generalized tonic-clonic epileptic seizure. Neuroradiological investigations showed an osteolytic lesion of the left frontal bone and an underlying brain lesion associated with recent signs of bleeding. The patie…
