pulmonar sequestration case report
TRANSCRIPT
Case description
• Male patient 59 years old.Male patient 59 years old.
• Current smoker.Current smoker.
• Presented with recurrent attacks of blood Presented with recurrent attacks of blood tinged sputum (average 3 attacks/ year).tinged sputum (average 3 attacks/ year).
• First attack started 12 years ago.First attack started 12 years ago.
Case description
• The patient was first investigated in the primary health care facility where chest X- ray was done.
• He was diagnosed as a case of bronchitis despite the obvious right paracardiac opacity.
Chest X rayRight paracardiac shadow
Case description
• The patient was treated with non specific treatment.
• patient was admitted to a general hospital due to another attack of hemoptysis with syncope.
• Thorax CT scan: o Right lower lobe opacity with calcification.
CT of the chestRight lower lobe opacity with calcification
Case description
• Due to the suspicious of malignancy:
ultrasonographic-guided aspiration was done twice.
• Pathological examination:o Fibrous tissue with dilated vascular spaces.
Case description
• The patient was referred to the chest department at the Mansoura university hospital for further evaluation and bronchoscopy.
• After revision of the history and chest radiology, pulmonary sequestration was suspected besides other benign lung lesions.
Case description
• CT angiography:
o Right intralobular pulmonary sequestration.
o Dual arterial supply from right pulmonary artery and multiple branches from abdominal aorta.
o The venous drainage into right pulmonary vein.
CT angiographyDual arterial supply from right pulmonary artery and multiple branches
from abdominal aorta.
Pulmonary sequestration
Pulmonary sequestration (PS)
• Congenital lung malformation:
o A mass of abnormal, nonfunctioning pulmonary tissue
o No communication with tracheobronchial tree
o Receive blood supply from an anomalous systemic artery (instead of pulmonary arterial system)
o Usually occur in the left lower lobe
Types of PS
Intralobar PS
75%
Within visceral pleura of a pulmonary lobe
Diagnosis is usually done at the second decade of life.
Recurrent infection is common.
Not associated with other anomalies
Extralobar PS
25%
Accessory lobe : tissue has its own pleura
Diagnosis is usually made in neonates or infants.
Often asymptomatic
Often associated with other anomalies:• Diaphragmatic hernia•Cardiac malformation•Foregut anomalies
Types of PS
Intralobar PSPS has visceral pleura of a lung lobe
Extralobar PSPS has its own pleura
Types of PS
Intralobar PSCystic changes and infection are
common
Extralobar PS
Infection is less common
Radiological assessment
CT angiography
• Simultaneously visualize:
oArterial supply.oVenous drainage.oParenchymal involvement of PS.
MRI
• Demonstrates:
oLocation of the lesion.oAberrant artery and venous drainage.
MRAExtralobar PS. Arrows referred to Aberrant blood supply.
Management
Management
• Symptomatic patient:
o Surgical resection with proper identification and
ligation of the feeding vessels.
Management
• Asymptomatic patient:
o Surgery is recommended.• Prevent recurrent infections and the unfavorable
cardiac influence caused by the existing aortopulmonary shunt.
Management
• Recent modalities:
1. Video-assisted thoracoscopic surgery (VATS).
2. Arterial embolization of the feeding vessels.
Conclusion
• The interesting points in our case
o The late presentation of the patient (59 years old)
o Unusual right-sided ILS o The double blood supply
from both pulmonary artery and abdominal aorta.
Conclusion
