Overview

[Disease name] must be differentiated from other diseases that cause [clinical feature 1], [clinical feature 2], and [clinical feature 3], such as [differential dx1], [differential dx2], and [differential dx3].

OR

[Disease name] must be differentiated from [[differential dx1], [differential dx2], and [differential dx3].

Differentiating [Disease name] from other Diseases

[Disease name] must be differentiated from other diseases that cause [clinical feature 1], [clinical feature 2], and [clinical feature 3], such as [differential dx1], [differential dx2], and [differential dx3].

OR

[Disease name] must be differentiated from [differential dx1], [differential dx2], and [differential dx3].

OR

As [disease name] manifests in a variety of clinical forms, differentiation must be established in accordance with the particular subtype. [Subtype name 1] must be differentiated from other diseases that cause [clinical feature 1], such as [differential dx1] and [differential dx2]. In contrast, [subtype name 2] must be differentiated from other diseases that cause [clinical feature 2], such as [differential dx3] and [differential dx4].

Differentiating [disease name] from other diseases on the basis of [symptom 1], [symptom 2], and [symptom 3]

On the basis [symptom 1], [symptom 2], and [symptom 3], [disease name] must be differentiated from [disease 1], [disease 2], [disease 3], [disease 4], [disease 5], and [disease 6].

Pulmonary embolism
  • On CT angiography:
    • Intra-luminal filling defect
  • On MRI:
    • Narrowing of involved vessel
    • No contrast seen distal to obstruction
    • Polo-mint sign (partial filling defect surrounded by contrast)
✔ (Low grade) ✔ (In case of massive PE) - - - -
Congestive heart failure
  • Goldberg's criteria may aid in diagnosis of left ventricular dysfunction: (High specificity)
    • SV1 or SV2 + RV5 or RV6 ≥3.5 mV
    • Total QRS amplitude in each of the limb leads ≤0.8 mV
    • R/S ratio <1 in lead V4

Percarditis
  • ST elevation
  • PR depression
  • Large collection of fluid inside the pericardial sac (pericardial effusion)
  • Calcification of pericardial sac
✔ (Low grade) ✔ (Relieved by sitting up and leaning forward) - - - - -
  • May be clinically classified into:
    • Acute (< 6 weeks)
    • Sub-acute (6 weeks - 6 months)
    • Chronic (> 6 months)
Pneumonia - - - -
Vasculitis

Homogeneous, circumferential vessel wall swelling

-
Chronic obstructive pulmonary disease (COPD)
  • On CT scan:
  • On MRI:
    • Increased diameter of pulmonary arteries
    • Peripheral pulmonary vasculature attentuation
    • Loss of retrosternal airspace due to right ventricular enlargement
    • Hyperpolarized Helium MRI may show progressively poor ventilation and destruction of lung
