Abstract
This case report discusses three developmental vascular anomalies (DVAs) observed in adults and highlights the challenges related to the diagnosis and management. Even though detected at early ages, diagnostic difficulties are observed in the adult age due to the scarcity and diverse clinical features. These cases illustrate the necessity of a multidisciplinary approach involving clinicians and radiologists for precise and prompt diagnosis in adults, where misdiagnosis and delays in intervention are frequent. The cases comprised a 17-year-old female with an absent right pulmonary artery and mitral stenosis, a 46-year-old female with chronic obstructive pulmonary disease (COPD), with an absent left pulmonary artery, and a 60-year-old female with bronchial asthma and tuberculosis exhibiting a rare DVA. This discussion highlights the importance of intensified clinical suspicion and thorough evaluation for the cases of unexplained respiratory symptoms and abnormal image findings in patients, which can further provide the medical community with valuable insights.
