Imaging findings of inflammatory myofibroblastic tumor in breast: A case report
Rationale:
Inflammatory myofibroblastic tumors (IMTs), particularly breast IMTs, are rare neoplastic lesions typically associated with a favorable prognosis. Breast IMTs are easily misdiagnosed as other types of malignant lesions, and therefore there is a significant unmet need for a better preoperational differential diagnosis based on imaging manifestations. Here, we report the imaging findings of a breast IMT and compare our findings with previously published features of breast IMTs.
Patient concerns:
The patient, a 43-year-old female, reported the presence of a palpable lump within her left breast. An ultrasound examination revealed an irregular hypoechoic mass with unclear boundaries. Mammography demonstrated a mass of heterogeneous and striped density with granular calcification. Magnetic resonance image (MRI) inspection displayed an irregular tissue lump with an undistinguishable boundary and a further dynamic contrast-enhanced MRI disclosed an associated efflux change.
Diagnoses:
Breast inflammatory myofibroblastic tumors.
Interventions:
Breast needle biopsy and mammary resection were performed. Pathological staining of the bulk resected tumor after preoperative preparation revealed that the tumor-like tissue was enriched for spindle cells arranged in fascicular clusters. Histopathological diagnosis and immunohistochemistry confirmed the mass as being a breast IMT.
Outcomes:
No metastatic recurrence was found during 6-month or 1-year follow-ups.
