Diagnosis of multiple pulmonary cavernous hemangiomas via dual-layer spectral CT: A case report
Rationale:
Cavernous hemangioma is a benign vascular tumor, which very rarely occurs in the lung. When appearing as multiple nodules on chest CT, this tumor can be misdiagnosed as metastatic malignancy.
Patient concerns:
A 72-year-old woman presented with incidentally found multiple lung nodules on chest radiograph.
Diagnoses:
Based on information derived from dual-layer spectral CT images, the possibility of slow flow vascular tumor such as cavernous hemangioma was suggested. A pathologic diagnosis of pulmonary cavernous hemangioma was made via video-assisted thoracoscopic biopsy.
Interventions:
After tissue confirmation, the patient was discharged without further intervention.
Outcomes:
The patient recovered without any event. Follow-up chest CT performed 6 months later showed no significant interval change in nodule size and distribution.
Lessons:
Material decomposition images obtained from dual energy CT can help physicians understand the character of tumor vascularity for an accurate diagnosis of pulmonary cavernous hemangioma.
