Dermatofibroma mimicking malignancy on integrated F-18 fluorodeoxyglucose PET-CT.

چکیده
A 31-year-old female with a history of ovarian cancer underwent an F-18 fluorodeoxyglucose (FDG) positron emission tomography-computed tomography (PET-CT) scan. The PET-CT demonstrated focal nodular uptake in the subcutaneous tissue of the back adjacent to the paraspinal muscles. Color Doppler ultrasonography examination demonstrated a vascular solid mass. The patient underwent biopsy followed by excision. The pathologic diagnosis was dermatofibroma. Although benign, dermatofibromas can have intense FDG uptake.

Diagnostic performance of 18F-FDG PET-CT in patients presenting with secondary neck nodes from an unknown primary
Introduction: Clinical examination and even anatomical imaging may fail to identify primary site of malignancy in patients presenting with cervical nodal metastasis. 18F-Fluorodeoxyglucose Positron Emission Computed Tomography (18F-FDG PET-CT) is known to overcome the limitations of anatomic imaging. Methods: Sixty-three (63) patient...
متن کاملRuptured epidermal cyst mimicking cutaneous melanoma on F-18 FDG PET/CT
F-18 FDG PET/CT provides an accurate staging and post-therapeutic evaluation of melanoma based on high metabolic characteristics of its primary and secondary lesions. This functional imaging modality may, however, detect coexisting benign lesions of inflammatory or infectious origin mimicking malignancy thus interfering with the staging of cancer. The authors present a case of ruptured epiderma...
متن کاملPrimary Benign Intraosseous Meningioma on 18F-FDG PET/CT Mimicking Malignancy
We present a case of primary benign intraosseous meningioma in the sphenoid bone mimicking malignancy. A 44-year-old female patient who had a protruding right eye and headache came to our hospital. MRI showed a large, destructive, heterogeneously well-enhancing soft tissue mass in the right sphenoid bone suggesting malignancy. (18)F-FDG PET/CT showed a hypermetabolic mass in the same site with ...
متن کاملRadiation therapy-induced phrenic neuropathy mimicking metastasis to the diaphragmatic crus on ¹⁸F-FDG PET/CT.
Benign unilateral uptake in the diaphragmatic crus is a relatively uncommon finding on (18)F-FDG PET/CT that can mimic the appearance of malignancy in patients with known cancer, as illustrated in this patient with neuroendocrine carcinoma. It is important for the PET interpreter to recognize this finding and attribute it to benign uptake based on the patient's history and symptoms at the time ...
متن کاملCandida esophagitis mimicking esophageal malignancy on 18FDG PET/CT.
Fluorine-18 fluorodeoxyglucose (18FDG) positron emission tomography-computed tomography (PET/CT) has been widely used in detecting malignancy. However, benign conditions, including infections and inflammatory lesions, may also show 18FDG accumulation (1). Although candida esophagitis is the most common cause of esophagitis in immunocompromised patients (2), it can also occur in patients with no...
