Cardiac metastasis mimicking acute myocardial infarction in a patient with urachal carcinoma: a case report and diagnostic dilemma

Figures

• 

  Figure 1. Pathological specimen. Pathological diagnosis: urethral cyst and moderately differentiated bladder adenocarcinoma. Based on immunohistochemical results and clinical history, findings (A) and (B) are consistent with intestinal-type adenocarcinoma of urethral cyst.

• 

  Figure 2. Pathological specimen. Pathological diagnosis: the provided lung tissue shows evidence of adenocarcinoma. In conjunction with immunohistochemical results and medical history, findings (A) and (B) are consistent with metastatic urethral cystic carcinoma.

  Figure 3. Electrocardiogram. There is sinus rhythm on the ECG. The aVR lead's PR segment is boosted. The ST segments leads I, II, V2, V3, V4, V5, and V6 show concave elevation.

  Figure 4. Electrocardiogram. Normal electrocardiogram.

  Figure 5. Coronary angiography. (A) demonstrates no stenosis in the left main artery. The left anterior descending (LAD) branch exhibits approximately 60% stenosis, while the left circumflex artery shows no stenosis. (B) reveals no stenosis in the right circumflex artery.

  Figure 6. Cardiac Doppler ultrasound. (A,B) show different views of cardiac color Doppler ultrasound revealing a localized hyperechoic lesion measuring approximately 40 × 35 mm in the posterolateral region of the left atrium, exhibiting mild hypoechoic characteristics. Metastatic lesions cannot be excluded.
