RESUMO
The diagnosis of adrenal insufficiency is discussed in case of low blood pressure and digestive symptoms. Rare inaugural abdomino-crural muscle contracture can be a misleading symptom. Here we report two new cases. A 50-year-old woman presenting a leaning forward walking attitude and negligence for the past 2 months was referred to the neurologic unit. Abdomino-crural contracture, clinical hypogonadism, and hyponatremia directed towards a panhypopituitarism, which was confirmed by subsequent investigations. Pituitary MRI found an empty sella turcica. The outcome was dramatic after hormone replacement therapy, with drawing up of the trunk and re-establishment of walking after a few days. The second case is a 58-year-old man, hospitalized with altered general condition, with a weight loss of 22 kg, and anorexia in the aftermath of a comminuted fracture of the right lower limb, complicated by pseudoarthrosis. There was amyotrophy on the extremities with intense cruralgia. The patient had an antalgic attitude in the flexion affecting his rehabilitation. During 1 year, the symptoms were mimicking psychiatric disorders, malabsorption, or cancer before the final diagnosis of central hypocorticism with normal MRI was established. The evolution was remarkable after a few days of therapy with hydrocortisone, where the myalgia disappeared, the patient quickly gained weight, and the disappearance of the retractions allowed rehabilitation. These two observations emphasize the delayed diagnosis of adrenal insufficiency in the case of abdomino-crural-related symptoms and the presence of misleading neurological symptoms. The mechanisms of this syndrome remain unknown.
