title: Case report. Ultrastructural changes of muscles during attacks of adynamia episodica hereditaria.
abstract: In an ultrastructural study of biopsies of quadriceps femoris muscle from two patients during attacks of adynamia episodica hereditaria. Marked pinocytosis along the sarcolemma and an interfibrillary oedema were observed, together with a 'bamboo-like' shape of the myofibrils. Other non-specific abnormalities were also found.
