Abstract

Fat necrosis of the breast is a benign condition that most commonly occurs as the result of trauma. The radiographic and clinical significance of fat necrosis of the breast is that it may mimic malignancy.

We present a case of false positive FDG PET/CT scan caused by fat necrosis and mimics local recurrence of breast carcinoma 3 years after radical mastectomy.

Physicians must be aware of fat necrosis as a potential pitfall for PET/CT. Fat necrosis must be considered in the differential diagnosis of hypermetabolic breast masses in patients who previously had mastectomy or mammoplasty.

Keywords:
FDG
PET/CT
Breast carcinoma
Fat necrosis
False positive
Resumen

La necrosis grasa de mama constituye una situación benigna que se produce de forma común como resultado de un trauma. El significado radiográfico y clínico de la necrosis grasa puede asemejarse a una neoplasia.

Presentamos el caso de un resultado falso positivo de la PET/TC con FDG debido a una necrosis grasa, y su semejanza con una recurrencia local de carcinoma de mama a los 3 años de una mastectomía radical.

Los facultativos deben ser conscientes de que la necrosis grasa puede constituir una limitación para el estudio PET/TC. La necrosis grasa debe considerarse en el diagnóstico diferencial de las masas hipermetabólicas de mama en pacientes sometidas previamente a mastectomía o mamoplastia.

Palabras clave:
FDG
PET/TC
Carcinoma de mama
Necrosis grasa
Falso positivo
