The study offers insights into PAM's genetics, clinical manifestations, diagnostic approaches, and treatment modalities. It highlights the importance of early diagnosis and management while discussing limitations such as its retrospective nature and small sample size. Despite these limitations, the study contributes significantly to understanding PAM and PH, emphasizing the need for larger prospective studies to validate findings and explore novel therapeutic avenues.
