INTRODUCTION

• Pleural hydatid disease is rare.• Tension pneumothorax and empyaema are also

rare.• A search through the net revealed less than 60

cases over 60 yrs all over the world.• Bakir F and Al-Omeri reported 5 cases of

Echinococcal Tension Pneumothorax in Iraq in 1969 for the first time.

• To the best of our knowledge, this is the 2nd report.

INTRODUCTION

• HEREIN, TWO LADIES WITH PNEUMOTHORAX AND EMPYAEMA SECONDARY TO INTRAPLEURAL RUPTURE OF PHC ARE PRESENTED.

• THE AIM OF THIS REPORT IS TO EMPHASIZE THAT INTRAPLEURAL RUPTURE OF PHC SHOULD BE CONSIDERED IN ANY PATIENT WITH PNEUMOTHORAX IN AN ENDEMIC AREA.

DISCUSSION

• PRIMARY PLEURAL HD IS DENIED TO EXIST.• IT IS ALMOST ALWAYS SECONDARY TO

PULMONARY OR HEPATIC HD.• PHCs MAY GROW INTO GIANT CYSTS…

ELASTICITY OF LUNG.• PHC MAY RUPTURE INTO BRONCHUS

( COMMON) OR• INTO PLEURA ( RARE).

PATHOGENESIS

• PHC USUALLY HAS A PERIPHERAL LOCATION.• THE ELASTICITY OF THE LUNG PERMITS A

HUGE SIZE.• INTRAPLEURAL RUPTURE RESULTS IN AIR,

FLUID AND MEMBRANE ENTRY INTO THE PLEURA.

• ABSORPTION OF FLUID RESULTS IN ANAPHYLAXIS.

04/14/2023 Prof. Abdulsalam Y Taha 30

PATHOGENESIS

• TENSION PNEUMOTHORAX MAY RESULT FROM A CHECK VALVE MECHANISM..• COMBINATION OF MASSIVE

PNEUMOTHORAX AND ANAPHYLAXIS MAY PROVE FATAL.• UNTREATED.. BPF AND EMPYAEMA.

04/14/2023 Prof. Abdulsalam Y Taha 31

MANAGEMENT

• Preoperative diagnosis is difficult.• In most of the reported cases, the diagnosis

was made at the time of thoracotomy.• In the acute phase: steroids for anaphylactic reaction and chest tube insertion for pneumothorax. Definite diagnosis and treatment:

thoracotomy.

04/14/2023 Prof. Abdulsalam Y Taha 32

MANAGEMENT

• Almost always, it is misdiagnosed as PTB ( high prevalence of PTB in areas endemic to PHD).• However, certain observations

may give hints..

04/14/2023 Prof. Abdulsalam Y Taha 33

WHICH OBSERVATIONS?

• Residence in an endemic area.• Drainage of crystal clear fluid via chest tubes.• Pieces of laminated membrane may plug the

tube.• Persistent air leak despite 2 or 3 chest tubes.• Features of anaphylaxis.• Exam of pleural fluid for scolices may be

positive.

04/14/2023 Prof. Abdulsalam Y Taha 34

ALSO..

• Eosinophilia• Chest radiograph may show an irregular

gas-fluid level.• CT scan of chest: may show the cavity of

the cyst as well as the laminated membrane.

04/14/2023 Prof. Abdulsalam Y Taha 35

CONCLUSIONS• Intrapleural rupture of PHC is rare.• Echinococcal tension pneumothorax may prove

fatal.• It should be considered in any patient with

pneumothorax in an area endemic to PHC.• Preoperative diagnosis is extremely difficult, though

certain observations may give hints.• Definite diagnosis and treatment is via

thoracotomy.• Thoracotomy should be done as soon as the patient

is stabilized and before development of empyaema.
