ICM Flashcards
What is this?
Staghorn Calculus of the left kidney
What is this?
Calcified gallstone
What is the abnormality and what is visible in the colon?
Watch batteries are visible in the stomach and faeces is visible in the colon
What is this?
Ureteric calculus
What is wrong in this X-ray?
Missing left leg
What is the pathology here and what may have caused it?
Air is present in the biliary tree, possibly caused by a cholecystectomy
What are the folds called in the large bowel and are they complete or incomplete?
Haustra, and they are incomplete
What are the folds in the small bowel called and are they complete or incomplete?
Valvulae conneventes- they’re complete
What is the most common cause of large bowel obstruction?
Tumour
Other causes- Sigmoid volulus of the sigmoid colon.
What is the pathology visible here?
Dilation of the small bowel
What can cause small bowel obstruction?
Adhesions
Hernias
Peritoneal tumour
What is visible in this x-ray?
Air under the diaphragm
Could be caused by bowel perforation
What is the name of the sign in this film?
Rigler’s sign
What signs indicate small bowel dilatation?
Valvulae conneventes (go all the way across)
Multiple loops
Central
No faeces present
4 signs that help you to determine it is the small bowel you are looking at on a abdominal radiograph?
- Folds go all the way across- Valvulae Conniventes
- No faeces present
- Central location and cannot be traced all the way around
- There is bowel adjacent to bowel
What position is an abdominal radiograph taken in?
Supine
What diameter indicates small bowel dilatation?
> size indicates 3cm
What is the maximum normal diameter of the large bowel?
6cm
Is this large or small bowel?
Small bowel
What are the 3 main causes of small bowel dilatation?
- Obstruction from adhesions
- Hernias
- Peritoneal malignancy
What is the typical lesion seen in the large bowel when a tumour is present?
‘Apple core’ lesion
What is this and what causes it?
Sigmoid volvulous and it is caused by twisting of the bowel
What sign is present in these radiographs and what does it indicate?
Rigler’s sign
It indicates there is free air in the abdominal cavity
What is wrong in this radiograph?
Two fractures in the rt. pubic rami
Present this radiograph
- Initially, no name, Hospital Number, Date film taken
- There is a marker
- No AP / PA marker – assume AP
- No indication of whether supine or erect – assume supine at start
- Bowel dilated –
- Position – central and bowel next to bowel
- Folds (valvulae conniventes) go all way across
- ie. Small Bowel Dilation
- Need erect Chest X-Ray to exclude perforation
What does each number refer to in this radiograph?
- Trachea
- Hilum – remember this comprises the bronchus, pulmonary blood vessels and the lymph nodes
- Lungs
- Hemidiaphragm
- Heart
- Aortic Arch
- Ribs
- Scapula or axilla
- Breast shadows
- Cardio-phrenic angle
- Costa-phrenic angle
What do you expect in a normal in a chest x-ray?
Position is PA and erect
Cardio-thoracic ratio should be less than 50%
What is wrong in this CXR?
It’s overexposed
Medical clips in the left lung
Patient has Situs inverta (NOT detrocardia as the stomach is also on the other side)
What is the pathology here?
Rt. Tension pneumothorax
How will a tension pneumothorax present?
Patient will be unwell
- Tracheal deviation
- Decreased chest expansion on right side
- Hyperesonance on right side
- No breath sounds on right side
What signs are worrying in this CXR?
Shadow in the Rt. lung
Unilateral pleural effusion (Lt. sided blunting of the costophrenic and cardiophrenic angles)
Increased Hilar markings
What is the pathology here?
Left pneumothorax
