Clinical Case Presentation & Differential Diagnosis

Template Overview

Clinical case presentations are the core educational ritual of modern medicine. In morning hospital rounds, clinical morbidity and mortality conferences, and medical board examinations, physicians must present complex patient stories with clarity, diagnostic precision, and therapeutic urgency.

When clinical presentations are disorganized, vital lab abnormalities are missed, diagnostic anchors bias the team, and patient safety is compromised.

This template provides a physician-grade Clinical Case Presentation format: de-identified demographic chief complaint, comprehensive SOAP structure, systematic differential diagnosis matrix, diagnostic workup results, and therapeutic management plans.

# Clinical Case: [Chief Complaint / Diagnosis] — [YYYY-MM-DD]

## 1. Subjective (History of Present Illness - HPI)
- **Patient Profile:** 54-year-old de-identified individual presenting with acute shortness of breath worsening over 48 hours.
- **Onset & Characteristics:** Sudden onset sharp chest pain, exacerbated by deep inspiration (pleuritic). Associated with mild hemoptysis and unilateral right calf swelling.
- **Past Medical History (PMH):** Hypertension, remote right knee arthroscopy 3 weeks prior. Zero history of coronary artery disease.
- **Medications & Allergies:** Lisinopril 10mg daily. No known drug allergies (NKDA).

## 2. Objective (Physical Examination & Diagnostic Labs)
- **Vital Signs:** BP 138/86 mmHg, HR 112 bpm (Sinus tachycardia), RR 24 breaths/min, SpO2 91% on room air, Temp 37.4°C.
- **Cardiovascular Exam:** Tachycardic, regular rhythm, normal S1/S2, zero murmurs or gallops.
- **Pulmonary Exam:** Clear to auscultation bilaterally; tachypneic with mild splinting.
- **Extremities:** Right lower extremity exhibits 2+ pitting edema, warmth, and calf tenderness compared to left.

### Diagnostic Workup & Laboratory Values
| Diagnostic Test | Observed Result | Normal Reference Range | Clinical Interpretation |
| :--- | :--- | :--- | :--- |
| Quantitative D-Dimer | 2,450 ng/mL | < 500 ng/mL | 🔴 Severely Elevated |
| High-Sensitivity Troponin | 18 ng/L | < 14 ng/L | 🟡 Mild Elevation (Right heart strain) |
| 12-Lead Electrocardiogram | Sinus tachycardia, S1Q3T3 pattern | Normal Sinus Rhythm | Right ventricular strain pattern |
| CT Pulmonary Angiography (CTPA) | Segmental filling defect in right lower lobe pulmonary artery | Normal vasculature | **Diagnostic for Acute Pulmonary Embolism** |

## 3. Assessment & Differential Diagnosis (DDx)
| Differential Category | Potential Diagnosis | Supporting Evidence | Evidence Ruling Out |
| :--- | :--- | :--- | :--- |
| **Leading Diagnosis** | **Acute Pulmonary Embolism (PE)** | Recent orthopedic surgery, unilateral calf swelling, hypoxemia, positive CTPA | Confirmed on imaging |
| **Must Not Miss** | Acute Coronary Syndrome (STEMI/NSTEMI) | Chest pain, elevated troponin, tachycardia | EKG shows RV strain without ST elevation; normal coronary history |
| **Must Not Miss** | Aortic Dissection | Sudden severe chest pain | Symmetrical blood pressures; lack of tearing pain radiating to back |
| **Alternative** | Pneumothorax | Pleuritic pain, tachypnea | Bilateral breath sounds present on exam; clear lung parenchyma |

## 4. Plan (Therapeutic Management & Clinical Disposition)
> [!IMPORTANT] Immediate Clinical Intervention
> Initiate therapeutic weight-based Low Molecular Weight Heparin (Enoxaparin 1mg/kg subcutaneously q12h).
> Admit to monitored telemetry step-down unit for respiratory monitoring.

- **Diagnostic Monitoring:** Repeat echocardiogram to quantify right ventricular systolic pressure.
- **Vascular Consultation:** Lower extremity venous duplex ultrasound to evaluate extent of residual deep vein thrombosis (DVT).
- **Patient Education:** Review long-term oral anticoagulation compliance and bleeding precautions.

# Clinical Case: Acute Pulmonary Embolism — October 6, 2026

## 1. Case Presentation
54yo patient presenting with pleuritic chest pain and calf swelling. CTPA confirmed right lower lobe pulmonary embolism.

## 2. Management
Started therapeutic enoxaparin. Admitted to telemetry. Echo ordered for RV strain.

When to Use and When to Avoid

When to Use

• Use during hospital morning rounds, clinical morbidity and mortality reviews, and medical board study.
• Use to format structured clinical SOAP notes and rigorous differential diagnosis matrices.
• Use to preserve de-identified medical educational case logs on local encrypted storage.

When to Avoid

• Avoid recording identifiable Protected Health Information (PHI) without proper institutional de-identification.
• Avoid using for non-clinical academic university courses.
