     Pediatric Radiology CasesRegion-Organ:

    Thorax-Lung  

     
     Pediatric Radiology CasesMost likely etiology:

    congenital  

     
     Pediatric Radiology CasesHistory:

    1 9/12 year-old boy. Reoccurring respiratory infections. In the X-ray (sent to us from another clinic), segmental, basal opacities on the left side.  

     
     Pediatric Radiology CasesPathomorphology or Pathophysiology of this disease :

    Pulmonary sequester = "Rokitansky-lobe"
    Congenital malformation of the lung.
    A mass of non-aerated pulmonary tissue that is not connected to the normal bronchial tree. It receives its own blood supply from a systemic artery.
    In 65% of the cases in the left lobe, otherwise in the right, posterior lower lobular segment.
    Two forms:
    Intralobular (75-85%) - without own pleura, drainage into the pulmonary veins.
    Extralobular (15-25%) - with own pleura, drainage into the vena cava/azygos vein.
     

     
     Pediatric Radiology CasesRadiological findings:


    MRI 1 <- view MRI 1

    MRI 1: T2-HASTE coronal: conically configurated, ca. 4x2cm large structure in the left dorsobasal lung, In the T2-weighted image, an obvious signal intensity increase is seen.







    MRI 2 <- view MRI 2

    MRI 2: T1-FLASH coronal with contrast: strong, homogenic, aortic synchronized enhancement of the sequestration after application of contrast. No aerated areas within this structure.







    MRI 3 <- view MRI 3

    MRI 3: MRA (MIP-Projections): Proof of the systemic arterial vasculature from the aotra and the venous drainage in the hemiazygos vein.













    MRI 4 <- view MRI 4

    MRI 4: MRA (MIP-Projections): Proof of the systemic arterial vasculature from the aotra and the venous drainage in the hemiazygos vein.









    MRI 5 <- view MRI 5

    MRI 5: MRA (MIP-Projections): Proof of the systemic arterial vasculature from the aotra and the venous drainage in the hemiazygos vein.










     

     
     Pediatric Radiology CasesDiagnosis confirmation:

    Imaging including endoscopy  

     
     Pediatric Radiology CasesWhich DD would be also possible with the radiological findings:

    In obvious sequester-vascular supply: none.  

     
     Pediatric Radiology CasesCourse / Prognosis / Frequency / Other :

    Congenital deformity.
    Often secondary hematogenic infection with delayed healing and sustained inflammatory symptoms due to missing aeration (no self-cleaning).
    Mostly, surgical resection. Sometimes also prophylactically due to the danger of infection.  

     
     Pediatric Radiology CasesComments of the author about the case:

    The presented case is the classical example of a lung sequester. Here, probably an extralobular sequester.
