  • 1. Clinical Materials forSelf Learning - Medicine. Prepared by Dr. Ajith Karawita MBBS, MD
  • 2. Objective• To provide collection of clinical materials for your learning in Clinical Medicine. ( These materials are open for further discussion in addition to descriptions provided ) Instructions• Do not rush, carefully examine and analyse each point.• Mail your suggestions – ajith.karawita@gmail.com
  • 3. Acknowledgement• I would like to express my sincere thanks to All patients.They have given their consent and fullest support for this exercise.• I am grateful to my teacher , Dr Christie De Silva. MD, FRCP, Consultant physician & Nephrologist, NHSL, Colombo.• My sincere thanks goes to Dr Wijelal Meegoda (MBBS, MD Radiology), Dr Ashanka Beligaswatta (MBBS, MD, MRCP) and Dr Darshani Wijewickrama (MBBS, MD) for reviewing this And to my colleagues who helped me immensely.• Dr T. Thulasi (MBBS, MD)• Dr Mathu Selvarajah (MBBS, MD)• Dr Ajantha Rajapaksha (MBBS, MD)• Dr Chamila Dabare (MBBS, MD)
  • 4. Case No -1• A 54 yrs old male patient presented with a history of shortness of breathing,• on examination- B/L ankle oedema, Cardiomegaly, and MR and MS were found,• Does cardiomegaly look appropriate to the lesion? Can there be an underlying cardiomyopathy or is it appropriate to the lesion. Comment .
  • 5. Don’t read description first: Here you can see cardiomegaly, and how the trachea isdivided at the carina, In pure Mitral Stenosis, you can see features of enlarged leftatrium which include 1. splaying of carina, 2. Elevation of left main bronchus 3. doubleright heart border with increased density.
  • 6. Case No -2• 24 years old young boy suddenly developed headache and found to have SAH and anterior communicating artery aneurysm which was clipped 3 months ago.• However he resumed unconsciousness and was in ICU for 3 months and developed acute on chronic renal failure and heamodialysis done.• Here you see the CT scan of brain. Identify the radiological abnormalities.
  • 7. Don’t read description first: Lateral ventricles dilated, 3rd ventricle is prominent,foreign body at anterior communicating artery area (according to the history probablythe clip). There are hypodense areas near the anterior horns of ventricle.

  • 9. Don’t read description first: Differential diagnosis could be 1. Pyogenicabscess, 2. Infected haematoma, 3. Cavitaing malignancy, 4. infectedbronchogenic cyst, 5. infected bullae – unlikely in this patient because the wallsare thicker than a bullae. In this kind of a lesion you have to examine features inthe wall, surrounding the wall, within the cvity and distribution of the lesion. Inmalignancy – walls are thicker and irregular than what you see here. Note thefluid level.
  • 10. Case No -4• A female patient presented with a history of fever, cough, right sided chest pain, and weight loss.• Examine the CXRs and describe the radiological abnormalities you see.

  • 12. Case No -5• A 36 yr old young patient presented with refractory hypertension and was investigated.• Two abnormalities found, one is parenchymal renal disease and the other one in renal angiogram.• Identify the lesion.
  • 13. Don’t read description first: Here you can see renal artery stenosis, usually inyoung it is due to fibromuscular narrowing, in old it is due to atheroma, In injectingHeroin users you can see a condition called Heroin arteritis presenting as renal arterystenosis.
  • 14. Renal Arteriogram report.• Through right femoral puncture, mid stream arteriogram was done, left renal artery osteal stenosis identified, selective left renal catheterization done, However balloon catheter didn’t enter the right stenosis ( baloon angioplasty could not be done ) suggest stenting or surgery.
  • 15. Case No -6• A 66 years old fat lady admitted with a history of tendency to fall to right side for about 2wks and oro-facial dyskinesia (jaw tremour) of about 1wk duration.• Cognitive functions were not affected, cog-wheel rigidity present. plantar was up going. She has a past history of Hypertension for 10 yrs.• most features are of Parkinsonism but atypical, so CT brain done.• Describe the abnormalities.
  • 16. Don’t read description first: Grossly dilated lateral ventricle, prominent 3rdventricle, choroid calcification compatible with age. There is peri ventricularoedema. Probably a normal pressure hydrocephalus. Features of normal pressurehydrocephalus include 1. gyri not widende, 2. Ventricles dilated etc..
  • 17. Case No -7• A 68 yrs old widow presented with sudden onset of LOC.• She is a known patient with hypertension, and diabetes mellitus on regular treatment. Including antiplatelet drugs.• Describe the lesion.• What will be the further management with regard to Antiplatelet therapy and clot evacuation.

  • 19. Case No -8• A 55 yr old male patient who has been treated twice for pneumonia in private sector, admitted again with fever, chills and right sided chest pain for 2 days duration.• Klebsiella and Strep. pneumoniae were isolated from sputum. Treated as right sided pneumonia, with iv Clarithromycin, Cefotaxime, metranidazole for two weeks. X-rays shows how it resolved.• Describe the radiological features in the process of healing.
  • 20. Don’t read description first: here you can see a series of CXR’s, which shows, howpneumonia resolved in this patient. In third CXR you can see a encysted effusionwhich was later resolved with continuation of antibiotics.
  • 21. Case No -9• A 68 yrs old male admitted with fever, chest pain, shortness of breath.• He also has right below knee amputation, and left foot eczema complicated with cellulitis.• Describe the chest x-ray.
  • 22. Don’t read description first : there is a haizyness at the lower zone of the right lung,but radiological assessment is difficult need to repeat the CXR (train you eyes for x-ray reading)
  • 23. Case No -10• This CXR is from a patient with decompensated alcoholic liver disease who presented with fever for 1wk.• Look at the X-ray. Is there any unusual appearance ?• How do you proceed.
  • 24. Don’t read description first: this is called “Apperently elevated diaphragm” inRadiology, causes could be above diaphragm, in the diaphragm and belowdiaphragm. Causes 1. Phrenic nerve palsy 2. Sub pulmonic effusion 3. Eventrationof diaphragm 4. Liver pathology.

  • 39. Don’t read description first:“Continuous Diaphragm sign ”
  • 40. Case No -16• In the next slide you see results of urine protein electrophoresis compared with normal diluted (1/50) serum protein electrophoresis.• What is your interpretation?
  • 41. urine protein electrophoresis compared with normal diluted (1/50) serum protein electrophoresis. Pt’s Urine Normal diluted serum (1/50) Gamma Beta Alb Alpha-1 Alpha-2Don’t read description first: Urine protein electrophoresis shows tubular proteinurea,No evidence of Benz Johns proteins.
  • 42. Case No -17• In the next slide you see serum protein electrophoresis of a patient and absolute amounts in grams per liter.• Interpret results.
  • 43. Control Total pro 65.6gL (65-85 ) Albumin 29.9gL (35-55 ) Alpha-1 3.8gL (3-5) Alpha-2 8.4gL (5-7) Beta 6.5gL (6-12) Gamma 17.0gL (9-15) Alb/Glob 0.8SampleDon’t read description first: Serum protein electrophoresis show low albumin andmild poyclonal gammopathy finding would be consistent with chronic liver disease.
  • 44. Case No -18 This is the result of serum electrophoresis of a patient who was investigated for lower backache and high ESR. Comment.Don’t read description first: There is increase of alpha-2 globulin with a slightpolyclonal increase of Gamma-globulin. Diagnosis is probably a infection
