  1. 1. By Fathima Hasan Mohamed Senior Radiographer Date: 22/08/2016 Food Signs in Radiology
  2. 2. Objectives • To provide the information and learn the characteristic radiological signs resembling various food items. • Discuss and illustrate the radiologic signs of a number of diverse conditions whose classic radiologic manifestations resemble various types of food. • Descriptive “food signs” are highly memorable and easily recognizable and allows a confident diagnosis on the basis of imaging findings alone or can narrow down the differential diagnosis.
  3. 3. Introduction • Radiologists have unique skills of observation and description • Pattern recognition is one of the techniques used in the interpretation of radiographs, and this skill improves with experience.
  4. 4. Selections from the Buffet of Food Signs in Radiology Fruits: • Apple core lesion • Berry aneurysm • Pear-shaped bladder • Lemon sign • Banana sign
  5. 5. Vegetable: • Celery stalk metaphysis • Onion skin periosteal reaction Meat, fish, and egg dishes: • (Hamburger sign, sausage digit, vertebral scalloping, eggshell calcification) Selections from the Buffet of Food Signs in Radiology
  6. 6. Pasta, rice, grains, and bread (carbohydrates): • linguine sign, rice grain calcification, miliary shadowing, cottage loaf sign Desserts, cakes, and candy: • Donut sign, omental cake, pancake vertebra, honeycomb lung, popcorn calcification, licked candy stick appearance Selections from the Buffet of Food Signs in Radiology
  7. 7. Dishes, cutlery, condiments: • Diffuse idiopathic skeletal hyperostosis [DISH] • Champagne glass pelvis • Dinner fork deformity • Salt and pepper calvaria • Coffee bean sign Selections from the Buffet of Food Signs in Radiology
  8. 8. Food Signs in Gastrointestinal Diseases Apple Core Lesion • The annular carcinoma of colon produces focal circumferential thickening of the bowel wall, narrowing of colonic lumen, associated with shouldering. • On barium examination, this gives rise an appearance of the affected colon similar to the partially eaten apple.

  13. 13. FOOD SIGNS IN BRAIN DISORDERS • Berry Aneurysm • The appearance of the intracranial saccular aneurysm on CT scan may resemble the size and shape of a berry hence termed berry aneurysm. They are congenital and characteristically occur at points where arteries bifurcate. • It may occur in isolation or in association with polycystic kidneys or coarctation of aorta.
  14. 14. Berry Aneurysm Berries. CT brain showing Berry aneurysm.
  15. 15. Berry aneursym
  16. 16. Banana Sign • The banana sign, is one of the many notable fruit inspired signs. • The banana-appearance of the cerebellum on the antenatal ultrasound is due to downward traction of the spinal cord and brainstem in neural tube defects hence giving the name banana sign. • It is also seen in the majority of fetuses with spina bifida, but disappears after 24 weeks. It is only rarely seen in a normal fetus. • There is very frequent concurrent hydrocephalus. • The same condition also gives rise to the lemon sign.
  17. 17. Banana Sign Banana Antenatal US of fetal head showing banana sign in the posterior fossa.
  18. 18. Lemon Sign • The appearance of the fetal cranial vault on antenatal ultrasound resembling lemon is an excellent indicator for open spina bifida. • The lemon sign refers to an abnormally shaped fetal head seen at antenatal US performed during the second trimester. The cranial vault appears lemon-shaped in axial cross section because the frontal bones are flattened or concave .
  19. 19. Lemon Sign Lemon Antenatal US of cranium showing lemon sign
  20. 20. Food Signs in Urogenital Diseases • Pear-shaped Bladder • The bladder assumes the shape of a pear when it undergoes extrinsic compression due to excess tissue in the pelvis. • The causes for the pear-shaped bladder include pelvic lipomatosis, pelvic hematoma, pelvic collection, pelvic masses, bilateral pelvic muscle hypertrophy or lymphadenopathy.
  21. 21. Pear-shaped Bladder Pears Cystogram showing pear-shaped bladder

  27. 27. Onion Skin Periosteal Reaction • In an aggressive bone lesion like acute osteomyelitis, Ewing’s sarcoma or osteosarcoma, the successive deposition of periosteal layers gives a lamellated or onion skin appearance on plain films. • Lamellated - Onion-skinning due to successive layers of periosteal development
  28. 28. Onion Skin Periosteal Reaction Onion skin showing whorls X-ray tibia revealing lamellated periosteal reaction on lateral aspect in Ewing’s sarcoma. multiple concentric parallel layers of new bone adjacent to the cortex
  29. 29. Hamburger Sign • Normally, at axial CT, the vertebral facet (apophyseal) joint space looks like a hamburger • When the facet joint is dislocated, the articular facets become uncovered, or naked, also called "naked facet sign”. • This CT sign is characteristic of a flexion- distraction injury and indicates severe ligamentous disruption and spinal instability. • It may be either unilateral or bilateral depending on whether facet dislocation is unilateral or bilateral.
  30. 30. Hamburger Sign Hamburger Axial CT Scan of a vertebra revealing presence of hamburger sign on right side and loss of hamburger sign on left side indicating flexion distraction injury.
  31. 31. Sausage Digit • Sausage is a minced and seasoned meat stuffed into cylindrical case of animal tissue frequently eaten in Europe. • The term sausage digits refer to the clinical and radiologic appearance of diffuse fusiform swelling of digits due to soft-tissue inflammation from underlying arthritis or dactylitis . • The most common cause of sausage digit is psoriatic arthropathy. • Other causes include osteomyelitis, sickle cell anemia, sarcoidosis, and tuberculous dactylitis (spina ventosa).

  36. 36. Eggshell Calcification
  37. 37. Food Signs in the Chest Diseases • Miliary Shadowing • The term miliary comes from "millet seed" popular birdseed. On the Chest radiograph, a pattern of diffuse, tiny, well-defined nodules of 2–4 mm in size is called “miliary shadowing”. This pattern is often seen with pulmonary tuberculosis . • The other differential diagnosis of miliary shadowing includes fungal infections, inhalational diseases, sarcoidosis, eosinophilic granuloma, and metastatic disease (particularly from thyroid tumors, melanoma, and choriocarcinoma).

  47. 47. linguine sign • After implantation of a silicone or saline breast implant, a fibrous capsule (scar) forms around the implant shell. In an intracapsular rupture the contents of the implant are contained by the fibrous scar while the shell appears as a group of wavy lines. • This has been termed the “Linguine sign” and has been most commonly described with MR imaging. Here, the same findings are seen on CT imaging in a patient with bilateral ruptured saline implants.
  48. 48. linguine sign Breast MRI showing the linguine sign indicating intracapsular implant rupture.

  53. 53. Pancake vertebra • A vertebra plana or pancake vertebra is the term given when a vertebral body has lost almost its entire height anteriorly and posteriorly, representing a very advanced crush fracture. • It is caused by trauma in normal vertebra or collapse of vertebral body in pathological spine like metastases, multiple myeloma, lymphoma, haemangioma, eosinophilic granuloma or osteogenesis imperfecta.
  54. 54. Pancake vertebra Pancake Reconstructed CT showing vertebral compression MRI showing vertebral plana
  55. 55. Licked Candy Stick Appearance • The term licked candy stick appearance refers to tapering of the tips of the metacarpal bones, metatarsal bones, phalanges, or clavicles and is usually associated with: • psoriatic arthropathy • rheumatoid arthritis • leprosy
  56. 56. Licked Candy Stick Appearance Candy sticks X-ray both feet showing tapered metatarsal ends in psoriasis
  57. 57. , Popcorn calcification • Cartilaginous tumors (such as osteochondromas, enchondromas, and chondrosarcomas) may produce irregularly shaped calcifications within their matrix that resemble popcorn on imaging studies. • These "popcorn calcifications" can usually be distinguished from the "mashed potato," or cloudlike, ossific matrix of bone-forming tumors such as osteosarcomas. • The term "popcorn calcification" has also been used to describe the lucent areas with sclerotic margins seen in the metaphyses and epiphyses of patients with osteogenesis imperfecta.
  58. 58. Popcorn calcification Popcorns 13 mm lung nodule with "popcorn" calcification.
  59. 59. Cottage Loaf Sign Cottage loaf bread, a traditional bread in U.K The MRI appearance of the partially herniated liver through the ruptured right Hemidiaphragm.
  60. 60. Coffee-bean sign • Coffee bean sign is a characteristic sign of sigmoid volvulus and consists of a greatly distended, air- filled loop of sigmoid colon extending from the pelvis at abdominal radiography. • The apposed medial walls of the dilated bowel form a distinct oblique line that resembles the cleft of a coffee bean. • The “coffee bean” arises from the pelvis and may be very large, with its apex often extending above the level of T10 to the left or right of midline.
  61. 61. Coffee-bean sign Case 1: with perforation Sigmoid Volvulus coffee bean
  62. 62. Champagne glass pelvis • The champagne glass pelvis is a helpful sign in achondroplasia which the iliac blades are flattened, giving rise to a pelvic inlet that resembles a champagne glass. The acetabular angles are increased, and the sacrosciatic notch is small.
  63. 63. Champagne glass pelvis Champagne glass X-ray pelvis in Achondroplasia
  64. 64. Champagne glass pelvis
  65. 65. Dinner fork deformity • In Colles’ fracture, the distal radius is fractured and angulated dorsally, giving rise clinically and radiologcally to the “dinner fork deformity” at the wrist . • This has typical resemblance to the dinner fork.
