[Symptomatically, the pathology of splenic gliomas is very difficult and the mental image, which is usually consequential, and contrast studies, which are sometimes of uncertain value, are of only some help. We distinguish primary and secondary splenic tumours on the basis of our cases. In the former, we consider a multicentric origin in the callosum-hemisphaerium angle very likely. The surgical option is very limited and the surgical mortality is very high. In the case of tumours of the corpus callosum, American neurosurgeons (Alpers (1), Voris and Adson (21), etc.) have emphasised for 25 years that surgery does not improve the patient's condition. Van Gehuchten's (23) position is correct: to refrain from surgery and to use Rtg. or radium therapy. ]
[The author reviews the literature on cases of paroxysmal paralysis in which irreversible musculoskeletal lesions have been demonstrated. He describes the relevant data of two hypokalemic and two hyperkalemic cases published with Hasznos and Solti. A significant proportion of paroxysmal paralysis cases develop persistent paresis and atrophy. The almost regular development of muscle lesions is confirmed by muscle biopsy findings. Muscle biopsy showed significant pathological changes in three of our cases where permanent paresis and atrophy were not present. Permanent muscle paralysis develops in the same muscles most affected by the seizure. The weakness of the pelvifemoral distribution and the hypervoluminal leg cramps are highly reminiscent of the muse, progr. pseudohypertrophic form of dystrophy. This is the reason why the association of these two pathologies has been frequently reported in the literature. After a critical analysis of these cases, the author concludes that there is no known case of paroxysmal paralysis and dystrophia muse, progr. in the same patient. The decisive evidence on this point is provided by the difference in the pathophysiological lesions. The muscle pathological lesion of paroxysmal paralysis is essentially vacuolar degeneration. The histopathological picture of hypokalemic and hyperkalemic cases is identical. The permanent muscular lesions of paroxysmal paralysis are the result of ion shifts and colloid chemistry changes associated with seizures. The paroxysmal osmotic changes initially result in reversible vacuolar formation. Later, irreversible degeneration of the loosened vacuolar centre of the muscle fibre is initiated. A metabolic myopathy associated with periodic recurrent potassium (and sodium ?) metabolism disturbances is therefore involved. The pathogenesis and pathomechanism of the muscle lesions just outlined are also likely to be due to a potassium-deficient diet and to myopathies induced by the administration of various glucocorticoids. ]
