RATIONALE: F-fluorodeoxyglucose positron emission tomography/computed tomography (F-18 FDG PET/CT) has an important role in the diagnosis of various malignancies. However, F-18 FDG can also exhibit intense accumulation in tissues in inflammatory conditions such as active tuberculosis (TB) and sarcoidosis. PATIENT CONCERNS: We report a case of a 52-year-old female with irritable cough. CT showed a lung mass with multiple bilateral lung nodules, and sarcoidosis was suspected...

Positron emission tomography (PET) with integrated computed tomography (CT) is a unique modality to noninvasively scan the whole body for diagnosing, staging and assessing response to therapy in various benign and malignant diseases. 18F fluorodeoxyglucose (FDG) is the most commonly used radiotracer for PET/CT imaging in cancer patients. FDG is a glucose analogue which is the predominant substrate for brain metabolism. As the brain cells are obligate glucose consumers, the knowledge of physiologic radiotracer uptake within the brain is imperative for correct interpretation of abnormal sites of metabolism...

If there is no pain in the temporal artery, the diagnosis of giant cell arteritis (GCA) may be delayed and blindness may occur. Therefore, FDG-PET/CT is important as a modality for diagnosis of GCA. When GCA is suspected and F-18 FDG-PET/CT is performed, it is worthwhile to pay attention to shoulder and hip joints as polymyalgia rheumatica commonly presents with GCA.

Rhabdomyosarcoma (RMS) is a rare cancer in adults, comprising about 1% of all forms of adult cancer. Common sites of metastases are lungs, skeletal system, lymph nodes, and brain. Metastases of RMS to pancreas are infrequent. We report a case of adult orbital alveolar RMS with pancreatic metastases detected in F-18-fluorodeoxyglucose-positron emission tomography/computed tomography.

Rectal carcinoma with metastasis to skeletal muscle is rare. So far, 16 cases of skeletal muscle metastasis from colorectal carcinoma have been documented of which only 5 were rectal carcinomas.([1]) We discuss here the case of a 69-year old male, a known case of mucinous adenocarcinoma status post neoadjuvant chemoradiotherapy and abdomino perineal resection, who presented with low backache 4 months post surgery. He was found to have metastasis to multiple skeletal muscles without the involvement of common sites, such as liver and lung...

Tracheal metastases from renal cell carcinoma (RCC) are extremely rare. Most common primary malignancy metastasizing to this unusual location usually comes from lung region while it is rare to have tracheal metastases from nonpulmonary malignancies such as breast, thyroid, colorectal carcinoma, and melanoma. The lesions detected on fluorine-18 fluorodeoxyglucose (F-18 FDG) positron emission tomography/computed tomography (PET/CT) scan, especially in the head and neck region, soft tissue, and muscular compartment during follow-up of RCC patients raise the possibility of metastatic lesions in these regions, though rarely encountered...

Eccrine carcinoma is an extremely rare malignant skin cancer arising from eccrine sweat glands with a high metastatic potential. It mainly occurs in the elderly, with equal incidence in both sexes. It usually spreads to regional lymph nodes, with liver, lungs, and bones being the most common sites of distant metastasis. Because of tumor rarity, little is known about the value of F-18 FDG PET/CT in evaluating this disease. Our case report aims to increase current knowledge of F-18 FDG PET/CT in eccrine sweat gland carcinoma as a noninvasive imaging tool for assessing the extension of the disease and detecting distant metastases...

Thyroid incidentaloma is defined as a new identified thyroid lesion occasionally detected during imaging studies. Incidence of thyroid incidentalomas is relatively rare in patients with lymphoma. Because of high rate of malignancy, these lesions with high intensity focal (18) FDG uptake detected on positron emission tomography with computed tomography (PET/CT) should undergo to biopsy regardless of size.
