Sub-diaphragmatic extralobar pulmonary sequestration (PS) is an extremely rare malformation defined as a portion of lung tissue that is totally discontinuous from the tracheobronchial tree and usually has its own pleural covering with an anomalous systemic blood supply. It is usually associated with other congenital malformations. The authors present an extremely rare case of isolated sub-diaphragmatic PS which was antenatally detected and followed up with postnatal ultrasound, where it masqueraded as a suprarenal mass; it was totally asymptomatic with spontaneous resolution at age of two years. This case emphasizes to add a differential diagnosis of malformation in congenital supra-renal masses, which remain stable in size and appearance, with possible spontaneous resolution and hence avoid immediate intervention and surgery.
膈下叶外型肺隔离症（PS）是一种极为罕见的畸形，定义为肺组织的一部分，与气管支气管树完全不连续，通常有自己的胸膜覆盖，并伴有异常的体循环血液供应。它通常与其他先天性畸形相关。作者报告了一例极为罕见的孤立性膈下叶外型肺隔离症病例，该病例在产前被检测到，并在产后通过超声进行随访，在此期间它伪装成肾上腺肿块；该病例完全无症状，在两岁时自行消退。该病例强调在先天性肾上腺肿块的鉴别诊断中增加对畸形的考虑，这些肿块在大小和外观上保持稳定，可能会自行消退，从而避免立即进行干预和手术。
