Ans: C Pulmonary venous hypertension

Explanation:
X Ray Findings - Chest
Heart & Blood Vessels

* Flask-shaped / Pear-shaped / Leathe- bottle / Money-bag shaped heart - Pericardial effusion
* Boot-shaped heart / Coer-en-sabot - Fallot's tetralogy
* Box shaped appearance - Tricuspid atresia
* Jug Handle appearance - Primary pulmonary artery hypertension
* "3" like appearance - Coarctation of Aorta

* Egg on side appearance - Transposition of great vessels
* Egg in cup appearance - Constrictive pericarditis

* Snow-man heart - TAPVC (total anomalous pulmonary venous connection)
* Figure of '8' - TAPVC (total anomalous pulmonary venous connection)
* Cottage Leaf appearance - TAPVC

* Pericardial calcification - Constrictive pericarditis
* Calcification in heart wall - is seen in - Carcinoid syndrome
* Calfication of ascending aorta - Atherosclerosis, Syphilis

* Hilar dance on fluoroscopy - Atrial Septal Defect
* Xray finding in Ebstein's anomaly - Pulmonary oligemia

* Posterior displacement of trachea - seen in - aneurysm of aorta
* Obliteration of left border of heart (PA view of chest) is - suggestive of - Lingular pathology (left lung)
* Bat's wings appearance - Pulmonary oedema
* Pruned tree appearance (of pulmonary circulation) - Pulmonary artery hypertension

Lungs

* Ground glass appearance - Hyaline membrane disease
* Solitary pulmonary mass lesion > 4cms - is most commonly due to - Bronchial adenoma
* Honey Comb appearance -
o SarcoidosisQ
o Histiocytosis XQ
o Interstitial lung diseaseQ
o TuberculosisQ
o Collagen disordersQ
o PneumoconiosisQ
o Drugs - bleomycin, busulphan, melphalan, cyclophosphamide


* Meniscus sign / Crescent sign (mobile mass in pulmonary cavity) is most commonly seen in - Aspergilloma (fungal ball lesion)
* Egg-Shell calcification - SilicosisQ , SarcoidosisQ , Coal miner's pneumoconiosisQ, Lymphoma following radiotherapyQ
* Pop-corn calcification / Craggy pop-corn calcification - Pulmonary Hamartoma

* Pleural calcification - commonest cause is - Tuberculosis (Asbestosis)
* Diaphragmatic Pleura calcification - is due to - Asbestosis
* Calcification in a pulmonary metastasis - is most commomly due to - Osteosarcoma
* Coin shadow in the lung (single), with calcification in the centre - Epidermoid carcinoma

* For radiologically evident pleural effusion - the minimal amount of pleural fluid that should be present is - 250 ml

* Plethoric lung fields - seen in - L-R shunts ( VSD, PDA, ASD)
* Oligemic lung fields - Pulmonary atreisa, Stenosis; Ebstein's anomaly
* Perihilar fluffy opacities - seen in - Pulmonary venous hypertension

Ribs

* Superior surface notch of ribs - seen in - Hyperparathyroidsm, Neurofibromatosis, Connective tissue disorders
* Inferior surface notch of ribs - seen in - Coarctation of Aorta, SVC obstruction, Chest wall AV fistula, Aortic Thrombosis,
* Unilateral notching of ribs - Coarctation of Left subclavian artery, Subclavian artery block, Blalock-Taussig Operation

Others

* Displacement of tracheal shadow - most common cause is - Thyroid swelling
* Water Lily sign - Ruptured hydatid cyst
