    Question 1. Regarding scimitar syndrome:
    (a) It has a female preponderance.

    True
    False

    (b) The most common pattern of lung drainage by the scimitar vein is partial lung drainage.
    True
    False

    (c) It shows left-to-right shunting which, if large enough, can result in pulmonary hypertension.
    True
    False

    (d) It is commonly associated with ventricular septal defect, right-sided aortic arch and pulmonic stenosis.
    True
    False



    Question 2. Regarding the scimitar sign:
    (a) It refers to a vertical curvilinear opacity parallel to the right heart border, which gradually increases in width along its caudal course before merging with the right lower cardiomediastinal silhouette.

    True
    False

    (b) It is specific for scimitar syndrome.
    True
    False

    (c) It can be seen in cases of meandering pulmonary vein.
    True
    False

    (d) Although lung hypoplasia and dextroposition of the heart are helpful signs, they can obscure the demonstration of the scimitar vein.
    True
    False



    Question 3. Regarding imaging of scimitar syndrome:
    (a) Chest radiography depicts all components of the syndrome, including the scimitar vein.

    True
    False

    (b) Cardiac catheterisation and angiography are the preferred modalities for establishing the diagnosis.
    True
    False

    (c) Conventional angiography is helpful in the evaluation of patients with high-grade pulmonary stenosis.
    True
    False

    (d) Air trapping in the horseshoe lung segment should alert the physician to the possibility of bronchial stenosis.
    True
    False



    Question 4. Regarding horseshoe lung:
    (a) Horseshoe lung commonly occurs in association with scimitar syndrome.

    True
    False

    (b) The isthmus lies posterior to the pericardial sac, oesophagus and aorta.
    True
    False

    (c) Unilateral pulmonary hypoplasia is a constant feature of horseshoe lung.
    True
    False

    (d) The bronchovascular supply to the isthmus is almost always from the normal lung.
    True
    False



    Question 5. Preoperative imaging for scimitar syndrome should evaluate for:
    (a) Total or partial pulmonary anomalous return.

    True
    False

    (b) Shunt fraction.
    True
    False

    (c) The presence of pulmonary hypertension.
    True
    False

    (d) The presence of bronchopulmonary collaterals.
    True
    False
