Abstract
RATIONAL: Hand-Schüller-Christian syndrome (HCS) is a rare disease with little clinical awareness, but the condition is more dangerous, and it combines with empty sella syndrome (ESS) which is extremely rare. PRESENTATION: A 26-year-old male patient who had proptosis, headaches, and diabetes insipidus for more than 10 years, and chronic cough and wheeze for 8 years presented to our hospital due to an abrupt onset of chest pain for 2 days. DIAGNOSIS: Hand-Schüller-Christian syndrome is diagnosed based on the typical clinical manifestations of diabetes insipidus and bilateral proptosis, magnetic resonance imaging (MRI) pituitary imaging and pathology. Empty sella syndrome is diagnosed based on hormonal indicators, clinical manifestations and MRI pituitary scan results. Type 1 respiratory failure and severe pneumonia can be diagnosed based on the results of clinical examination, chest imaging (including chest x-ray and computed tomography), pathology and blood gas analysis. Left pneumothorax can be diagnosed with chest imaging. INTERVENTIONS: "Meropenem and Cefdinir" were given for antimicrobrial coverage, "Desmopressin acetate" for anti-diuretic treatment, "Forcodine" for cough relief, "Ambroxol and acetylcysteine" for phlegm reduction, and continuous closed chest drainage was performed. OUTCOMES: The patient discharged after cough, wheezing, headache and other symptoms improved, and vital signs were stable. The patient has been followed up once a month for 17 months ongoing after discharge. At present, symptoms such as cough, sputum, and wheezing have improved considerably, and the mMRC score of dyspnea is 2 points. The reexamination of the chest X-ray shows that the absorption of lung exudates is better than before, and there is no recurrence of pneumothorax. LESSONS: Consider whether isolated diabetic insipidus is related to HSC, and if so, conduct an MRI, a biopsy, and other examinations as soon as possible.
