Imaging Findings and Coil Embolization of A Coronary Artery Fistula

Elastofibroma dorsi is a rare, benign tumor, characterized by fibroblastic proliferation and accumulation of abnormal elastic fibers. It is located in the subscapular region between the scapula and the thoracic wall. Especially, the suspicion of soft tissue sarcoma may produce anxiety. Magnetic resonance imaging and computed tomography findings are usually typical; and, positron emission tomography may also contribute to the diagnosis. Diagnosis can be made easily with typical localization and imaging findings. We present clinical and imaging findings in three cases of elastofibroma dorsi.

Testicular adrenal rest tumor (TART) is a benign testicular tumor that was seen in male patients with a history of congenital adrenal hyperplasia. It is often localized as bilateral. It can cause infertility. Differential diagnosis includes, Leydig and Sertoli cell tumors, seminomas and other germ cell tumors. Ultrasonography and magnetic resonance imaging are radiological imaging methods used in the diagnosis of TART. In this article, clinical features, radiological findings and differential diagnosis of TART is presented.

Demonstrating the imaging findings of asymptomatic giant thymolipoma mimicking cardiomegaly is aimed. A paracardiac mass was detected with 32-year-old male patient afterwards demonstration of cardiomegaly on a posterior-anterior (PA) chest x-ray examination taken for a routine control. Computed tomography (CT) showed a mass, localized in the anterior mediastinum, with smooth margins, showing no significant invasion of adjacent structures, and including fat density with fibrous component. The diagnosis was reported as thymolipoma histopathologically after transthoracic biopsy. On a preoperative magnetic resonance (MR) examination, taken for detailing the limits of the lesion, the mass showed hyperintensity on both T1 and T2 weighted images, and suppression on fat saturated T2 weighted images. No invasion of adjacent structures was detected. A thymolipoma may reach a large size without symptoms due to its great pliability. It can mimic cardiomegaly on x-ray images. Adipose tissue on CT is helpful in the diagnosis. MRI gives valuable information in determining the exact boundaries of the lesion.

Fever of unknown origin is defined as the following a temperature greater than 38.3°C (101°F) on several occasions, more than 3 weeks’ duration of illness, and failure to reach a diagnosis despite 1 week of inpatient investigation. Evaluation of patients with FUO is complicated because there are multiple etiologic factors and new ones are adding in literature every day. A 24years old man was performed contrast enhanced CT for FUO and abdominal pain, show trombus in portal vein and superior mezenteric vein. On examination, metiltetrahidrofolate reductase gene polimorphism is detected in the etiology of trombus. The patient’s fever and abdominal pain improved after 5 day treatment of Clexane 0,8 ml. A further doppler sonography show partial regression in trombus by which time the patient’s symptoms resolved. We aimed to present clinical and radiologic imaging findings in a case of portal and superior mesenteric vein trombus associated with MTFHR-C677T gene polimorphism which is a rare cause of FUO and we didn’t meet in the literature.

İnternal derangement of temporomandibular joint (TMJ) has been described as abnormal relationship beetween the disc, articular eminence, fossa and condyl. İn this study it vvas compared to magnetic resonance imaging and clinical findings of internal derangement of TMJ. Hundered seventy nine joints of hundered patients, who vvere referred from Selçuk University Faculty of Dentistry with daim of internal derangement in their TMJ vvere examined by MRI. Examination vvas performed at closed and opened mouth position in T1, T2, proton vveighted oblique sagittal plane and closed mouth position in coronal plane. These joints vvere joints vvas divided into four groups as normal, reducted (RA), İrreducted (IRA) and with or vvithout degenerative joint changes according to MRI findings. Clinically they vvere classified as in early, intermediate and late stage. Most of the cases vvere in intermediate (%37) and late (%43) stages. İn early, intermediate, late stages the joints vvere determined normal: 66%, 42%, 10%; RA .26%, 44%, 23%; IRA: 8%, 14%, 67% by MRI respectively. İn RA and IRA joints pain 64%, 83%, limited mouth opening 23%, 66%, clicing 62%, 26%, crepition 11%, 39% vvere found by clinical examination, respectively. Degenerative change of osseos component at the joints vvere freçuently seen in the joints vvith IRA and crepitation. İn the clinical examination of TME vvere significant findings. Also the presence of osseos degenerative changes, vvhich could not be determined by clinical examination, are very important. Because they influence the treatment type and effctivity. We think that in determination of TME joint disfunction, clinical examination and MR findings should be evaluated together.

Magnetic resonance imaging provides high contrast, anatomic delineation of the neck and is useful for preoperative localization of abnormal parathyroid glands in patients with persistent or recurrent hyperparathyroidism. Magnetic resonance imaging findings of the parathyroid masses are reported in three patients with hyperparathyroidism.

Vertebrobasilar dolichoectasia refers to a markedly dilated and tortuous vertebrobasilar arterial system, occasionally presenting with thomboembolic episodes or symptoms related to local compressive effects, such as cranial nerve palsies. Vertebrobasilar dolichoectasia is an uncommon cause of hiccups. A rare cause of hiccups, vertebrobasilar dolichoectasia is presented with imaging findings.

Aim: Cardiac masses are rare and categorized as non-neoplastic and neoplastic. Different imaging
methods play a vital role in the diagnosis and surgical planning of cardiac masses. Echocardiography
is the primary method of mass detection. Computed tomography (CT) and magnetic resonance imaging
(MRI) are used to detect and monitor cardiac masses. In this study, we aimed to evaluate the role of
radiology in the detection of rare cardiac masses and treatment planning.
Patients and Methods: Admission symptoms of five patients with cardiac masses detected in our
radiology unit between 2018 and 2021, the imaging methods in which the lesions were determined, and
whether the imaging findings were consistent with their patholo gical diagnosis were evaluated.
Results: The masses of patients diagnosed with lymphoma, pleomorphic sarcoma, and hemangioma
were larger than 3 cm. The margins of the malignant masses were ill-defined, and invasion into adjacent
structures was seen. Cardiac hemangioma, pericardial cyst, and myxoma had diagnostic radiological
findings.
Conclusion: It is significant to know the imaging findings according to the pathological diagnosis of
cardiac masses in patient management and treatment planning.
