    Ok. Just throwing some things out there (reluctantly)! Dr. Wood–don’t kill me.

    Case 1: Destruction of cortication on R coranoid notch with radiolucency inferior to this(loss of trabecular bone). Bone at inferior nasal cavity also appears to have lost it’s cortication and possible resorption of root 11.

    Case 2: Bilateral mandibular loss of cortication at superior ridge (i.e. 33-38 area and 43-48 area). Possible R fracture of coranoid notch. Radioopaque lesion L sinus.

    Case 3: Unable to follow medial wall of R max sinus–destroyed? Large radioopaque lesion in R mandible possible obliterating part of the mandibular canal.

    Case 4: multilocular radiolucent lesion (moth-eaten) throughout the body and ramus of the mandible, extending both above and below the mandibular canal and extending close to the inferior border of the mandible.

    Case 5: Unable to see medial walls of sinus. Pathology around 38. (radicular cyst). Clouding (radioopacities both nasal cavities and loss of cortication L medial and inferior wall of sinus; Possible large non-corticated radiolucency associated with 35 apex and extending to 36 mesial root and extending below inf .alv canal. Unknown radiolucency in L ramus but who ramus is not visible in pan.

    Case 6: 2 Large radioopacities in L sinus- region. Unable to see sinus walls L side nor nasal anatomy which appears to be obliterated by same radioopaque material. Possible radiolucent lesion 25/26.

      It’s too late I am coming directly for you – and I am armed for bear! No seriously – take your time and download the “thing” / checklist and first of all
      1. Identify your regions of interest.
      2. Position Size Extent
      3. Overall general description
      4. Features of the border/margin/periphery
      5. What internal structure is present
      6. What affect had the region of interest had on adjacent structures.
      Following this will make your observations (which are a great start) more thorough and if nothing else buy you a couple of minutes to goof around while you figure out what these things are NOT. After figuring out what they are NOT then we can winnow down to what they might be… forming a differential interpretation
