Abstract
This case report describes the clinical course of a 73-year-old postmenopausal female presenting with a persistent cough, breathlessness, and hypertension. Upon examination, she exhibited signs of respiratory distress, prompting transfer to the intensive care unit (ICU) where type 1 respiratory failure was diagnosed. Chest imaging revealed bilateral lung opacities, leading to a diagnosis of lung metastasis. Subsequent screening investigations unveiled endometrial carcinoma with atypical respiratory symptoms, highlighting the importance of thorough evaluation. Despite prompt management and biopsy confirmation, the patient's condition rapidly deteriorated, underscoring the aggressive nature of metastatic endometrial carcinoma. This case underscores the necessity of considering atypical presentations and timely intervention in managing such malignancies.
