Summary
Castleman disease in the anterior mediastinum can mimic pulmonary sequestration. Imaging revealed prominent systemic vessels, highlighting the need for careful differential diagnosis in mediastinal masses.
Area of Science:
- Thoracic oncology
- Diagnostic imaging
- Vascular anomalies
Background:
- Mediastinal masses present a diagnostic challenge.
- Castleman disease is a rare lymphoproliferative disorder.
- Pulmonary sequestration is a congenital lung malformation.
Observation:
- A 39-year-old woman presented with an anterior mediastinal mass.
- Computed tomography and magnetic resonance imaging demonstrated prominent systemic arterial feeding vessels and a systemic draining vein.
- The imaging findings mimicked an anterior mediastinal pulmonary sequestration.
Findings:
- The patient was diagnosed with anterior mediastinal Castleman disease.
- The vascular characteristics on imaging led to initial misdiagnosis.
- Castleman disease can present with atypical vascular features.
Implications:
- This case underscores the importance of considering Castleman disease in the differential diagnosis of anterior mediastinal masses with prominent vascular supply.
- Advanced imaging techniques are crucial for differentiating mediastinal lesions.
- Accurate diagnosis is essential for appropriate treatment planning.
