    A Rare Case of Primary Cardiac Diffuse Large B-cell Lymphoma Imaged with F-18-FDG PET/CT
    (2022) Erhamamci, Seval; Aslan, Nesrin; 35771036
    Primary cardiac lymphoma is an extremely rare malignancy. A few reports about the findings of (18)fluorine-fluorodeoxyglucose (F-1(8)-FDG) positron emission tomography/computed tomography (PET/CT) imaging has been presented. We report a rare case of a 70-year-old male with diagnosed primary intracardiac diffuse large B-cell lymphoma referred for F-18-FDG PET/CT imaging for initial staging. The scan revealed an abnormal hypermetabolic gross tumoral lesion involving the right atrium and auricula. After completing three cycles of chemotherapy, post-treatment F-18-FDG PET/CT showed complete response.

    Comparative Findings Between Ga-68-PSMA and F-18-FDG PET/CT for Hepatocellular Carcinoma
    (2020) Erhamamci, Seval; Aslan, Nesrin; 0000-0001-5016-4650; 33094578
    We have reported here the case of a 69-year-old man who presented with spinal cord compression due to bone metastases as the first manifestation of hepatocellular carcinoma (HCC). For the initial staging, the patient underwent F-18-fluorodeoxyglucose (FDG) positron emission tomography/computerized tomography (PET/CT) imaging, which demonstrated mild F-18-FDG uptake in the multiple expansile osteolytic bone lesions, but no remarkable atypical F-18-FDG uptake in the liver lesion on low-doses CT. An additional PET/CT scan was performed to evaluate the prostate-specific membrane antigen (PSMA) expression, which has recently been reported to be a potential biological marker in a variety of tumors including HCC. High PSMA uptake was recorded in both the metastatic bone lesions and the primary liver lesion/tumor by the Ga-68-PSMA PET/CT.

    A Case of Primary Colon Carcinoma Demonstrated by FDG PET/CT Imaging After Detection of a Solitary Brain Metastasis
    (2015) Erhamamci, Seval; Reyhan, Mehmet; Nursal, Gul Nıhal; Torun, Nese; Yapar, Ali Fuat
    The detection of brain metastases as the initial manifestation of colorectal carcinoma without liver or lung involvement is extremely rare. Herein we present a case of a 52-year-old male patient with an unusual presentation of colon cancer, with primary lesions demonstrated by fluorine- 18-labeled fluorodeoxyglucose (FDG) Positron-emission tomography/computed tomography (PET/CT) after detection of a solitary brain metastasis. Brain CT images revealed a brain tumor. Histopathologic evaluation indicated metastatic poorly differentiated adenocarcinoma, while his physical examination was normal. The PET/CT revealed abnormal intense FDG uptake in the right parietal region and in descending colon, with no other abnormal FDG uptake elsewhere in the body. The histopathologic diagnosis of the descending colon lesion revealed moderately differentiated adenocarcinoma. This case indicates that FDG PET/CT imaging may have a positive impact on the evaluation of patients with brain metastasis from an unknown primary.

    Venous thrombosis of sarcoidosis as an unusual incidental finding on 18F-fluorodeoxyglucose positron emission tomography/computed tomography
    (2015) Erhamamci, Seval; Reyhan, Mehmet; Yapar, Ali Fuat; Canpolat, Tuba; 26430325
    Sarcoidosis is defined as a multisystem granulomatous disorder of unknown cause. Venous thrombosis (VT) in the sarcoidosis is rare. The routine use of 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) has resulted in clinicians detecting many incidental findings, which have proven to be clinically significant such as thrombosis. Here, we present a case with VT of sarcoidosis in the inferior vena cava and portal vein as an unusual incidental finding on 18F-FDG PET/CT.
