ABSTRACT
Malignant mesotheliomas are rare entities (0.1-0.2% of all malignant tumors) possibly localized at the pleura, peritoneum, pericardium, and tunica vaginalis. Most malignant mesotheliomas are caused by asbestos inhalation. We report on a man who suffered from malignant mesotheliomas of the tunica vaginalis and of the pleura simultaneously. The development of these tumors was probably multicentric; the patient had been exposed to asbestos over a period of 22 years. We discuss the individual findings and the current literature.

The availability of MRI has turned out to have less impact on the epidemiology of MS than originally expected. Only 3/69 patients diagnosed between 1986 and 1990 in the epidemiologic area of South Lower Saxony (Germany) would have been missed without MRI. However in 18/50 patients the diagnostic classification changed, mostly from possible to probable MS. As we included possible cases from the beginning of our studies, the overall figures remain essentially unchanged. Epidemiologists who excluded possible cases from their surveys may experience more problems with the introduction of MRI.

Adrenal hemorrhages in newborns are usually diagnosed by sonography. Magnetic resonance imaging is indicated when morphological change, clinical appearance and follow-up do not allow differentiation of adrenal hemorrhage and neuroblastoma. Using artefact-suppressing sequences, the adrenal gland can be examined with modern MRI systems. The adrenal gland hemorrhage is characterized by a typical signal behaviour. If a haematoma persists over a longer period, a circular methemoglobin zone can be observed. An additional contrast application (Gadolinium-DTPA) can aid in demonstrating vascular tumors.

The accompanying central nervous system (CNS) malformation in thoracoabdominal evisceration syndrome has up till now not been given much attention. Two such cases in the early fetal stages are demonstrated here, in which CNS anomalies were severely dysraphic. It is possible that babies with the evisceration syndrome are less capable of surviving when the CNS complication is severe. This may well be the reason why CNS complication of the syndrome has seldom been observed.

Short TR (time repetition) and TE (time echo) images usually display pathologic structures unsatisfactorily. Tumors appear larger in MR than in computer tomography (CT). Additional examinations with intensive x-ray exposure are not necessary, as the better soft tissue contrast in MR allows for a distinct demarcation of the pathologic structure. T2-weighted images of brain stem angioma and pinealoma are not better than T1-weighted images. In the skull-base area, the sagittal plane best displays the anatomical-pathological relationship. The second plane is necessary for three-dimensional demarcation. On the second plane, the use of identical sequences is helpful, as the optical comparison of light intensity in pathologic tissue is easier.

Ganglioglioma in the temporal lobe was encountered in 0.6% of a series of 998 patients undergoing biopsy for intracranial tumors. It was more frequent in young adults and children. Seizures were the main symptom and had been present over a long period of time in some patients. Clinical examination also revealed intracranial pressure, focal signs, and behavioral problems, but these symptoms were not always evident. Electroencephalography was not specific. Calcifications were visible on computerized tomography (CT) in five cases. The cystic and well-circumscribed aspects of these tumors were apparent on CT scans; these features were confirmed at operation and on magnetic resonance imaging (MRI), when it was also found that the tumors were partially solid. Therefore, MRI seems to be a useful diagnostic method, particularly when a cystic tumor is revealed on CT, and is also valuable for postoperative monitoring. Surgical treatment for ganglioglioma is recommended, with total extirpation if possible.

The first reported findings on CT and N.M.R. in two cases of idiopathic peripheral lymphoedema are described. These methods have compared with the generally available volume estimations (volume estimation according to Kuhnke, immersion plethysmography) and have been considered in relation to visual and lymphographic examinations.
