CTICasesAbsent Right Upper Fissure
Imaging findings
CT chest shows a complete absence of the right minor (horizontal) fissure and a normal tracheobronchial and pulmonary vascular branching pattern in the right lung.
Key takeaways
Incomplete or absent lung fissures are common congenital anatomical variations. An absent minor fissure can lead to atypical patterns of fluid accumulation or consolidation, simulating a mass or atypical lobar disease on radiographs.
