intraosseous ganglia can affect the carpal bones of the hand and must be considered in the differential diagnosis of wrist pain. a 38-year-old female presented with a 14-month history of left wrist pain and a radiolucent cystic lesion was seen computed tomography (ct) scanning. characteristic radiographic findings of a cyst in association with a fine sclerotic rim was apparent. we report an unu...

fewer than 15% of lipomas occur in the head and neck. lipomas of the larynx are very rare benign laryngeal tumors (0.6%). to date less than 100 case of laryngeal lipoma have been reported in the literature.clinical manifestation include progressive horseness, dyspnea, and even dysphagia. in the direct exam smooth or pedunculated mass is seen in the larynx and sometimes if tumor is large enough ...

(PET) and computed tomography (CT) are increasingly used for oncologic imaging. In particular, positron emission tomography with fluorine-18 fluorodeoxyglucose (F-FDG PET/CT) is suggested as a more useful modality for accurate, non-invasive imaging in predicting the prognosis and staging of breast cancer (1-4). The combination of positron emission tomography (PET) and computed tomography (CT) p...

Primary hepatic neuroendocrine tumors (PHNETs) are extremely rare neoplasms. Herein, we report a case of a 70-year-old man with a hepatic mass. The non-contrast computed tomography (CT) image showed a low-density mass, and dynamic CT images indicated the enhancement of the mass in the arterial phase and early washout in the late phase. F18- fluorodeoxyglucose (18F-FDG) positron emission tomogra...

Evaluation of calcified metastatic lesions by conventional imaging can be challenging. Ovarian cancer metastases can present with calcification which might increase in size and number following therapy. It is not entirely clear whether these calcifications are associated with tumor response or disease progression. Calcified lesions which do not change in size or configuration are particularly p...

Background: To explore computed tomography (CT) characteristics of the 2019 novel coronavirus (COVID-19) pneumonia and variations among different clinical types.

objective(s): this study aimed to compare the diagnostic values of 11c-choline and 18f-fluorodeoxyglucose (18f-fdg) positron emission tomography/computed tomography (pet/ct) in patients with cholangiocarcinoma (cca). methods: this prospective study was conducted on 10 patients (6 males and 4 females), aged 42-69 years, suspected of having cca based on ct or magnetic resonance imaging (mri) resu...

metastasis from a malignant tumor to the palatine tonsils is rare, accounting for only 0.8% of all tonsillar tumors, with only 100 cases reported in the english-language literature. various malignant lung carcinomas may metastasize to the tonsils. a few cases of tonsillar metastasis from neuroendocrine lung carcinoma have been reported. a 67-year-old female underwent a right tonsillectomy becau...

Computed tomography (CT) is a frequently performed examination in women of all ages. In all thoracic CT examinations of the chest at least parts of the breasts are included. Therefore incidental breast pathology may be observed. It has been suggested that one out of 250 women undergoing chest CT will show a malignant incidental breast lesion. Given the high number of performed chest CT examinat...
