    Primary breast tuberculosis: imaging findings of a rare disease
    (2021) Baykan, Ali H.; Sayiner, Hakan S.; Inan, Ibrahim; Aydin, Elcin; Erturk, Sukru M.; 0000-0003-0907-3647; 33587199; AAI-8276-2021
    Breast tuberculosis is a rare form of extrapulmonary tuberculosis which tends to affect females of reproductive age, and is much rarer in males, postmenopausal women, and pre-pubescent girls. It is difficult to diagnose because it can mimic benign conditions such as a fibroadenoma, as well as malignant diseases like a carcinoma. It is also particularly difficult to distinguish breast tuberculosis from granulomatous mastitis, so other possible diagnoses should be ruled out first. The diagnosis of breast tuberculosis has three essential pillars: clinical examination, radiological evaluations, and histopathological sampling. Radiological evaluations are not only critical in diagnosis but are also important in the planning of the treatment and during the follow-up. This paper aims to review the imaging findings and the differential diagnosis of breast tuberculosis.

    (2021) Aydin, Elcin; Soylev, Gozde Ozcan; Muratli, Sedit Kivanc; Limnili, Bora Bora; Boya, Hakan; Tekindal, Mustafa Agah; Agildere, Muhtesem; 0000-0001-8742-5543; 0000-0001-8742-5543; 31107427; AAI-8276-2021; AAJ-4917-2021
    The practicality of real-time sonoelastography in the diagnosis of tendinopathy is being discussed since the beginning of its use in musculoskeletal system. The aims of this study were to compare the elasticity of pathologic supraspinatus tendon with the uninvolved side by sonoelastography and to determine the relationship between the sonoelastographic findings and magnetic resonance imaging (MRI) grade of the tendinosis. Eighty-2 patients (50 males, 32 females, mean +/- SD age = 53.61 +/- 16.15 years, range = 20-84 years) with unilateral supraspinatus tendinosis were included in this study. Three grades of tendinosis were identified in MRI (grade 1: mild, grade 2: moderate, and grade 3: severe). The strain ratio (SR) of the tendinosis area to the healthy normal area of the same tendon tissue and SR of the tendinosis area to ipsilateral subcutaneous fat tissue were evaluated with sonoelastography. The SRs of the tendinosis areas were also compared with the control (contralateral) side tendon tissue and subcutaneous fat tissue of the same patients. Between-groups comparisons were also done according to the MRI grading. Statistical analysis was done using paired t test (P < 0.005 was considered statistically significant). There was a statistically significant difference in the comparison of the SRs of the tendinosis areas to subcutaneous fat tissues on ipsilateral shoulders (TA/SFT) and the healthy supraspinatus tendon area (TA/ST) of the same shoulder. There was also statistically significant difference when compared with the control side measurements (P < 0.01). In patients who have grade 1 and grade 3 tendinosis on MRI, there was statistically significant difference between elastrographic evaluation of affected and unaffected sides. Real-time sonoelastography is a reliable diagnostic method in patients with rotator cuff tendinosis and shall be kept in mind as a noninvasive, inexpensive, and practical diagnostic test in suitable cases.

    (2019) Eraslan, Cenk; Acaer, Ahmet; Guneyli, Serkan; Akyuz, Esra; Aydin, Elcin; Colakoglu, Zafer; Kitis, Omer; Calli, Mehmet Cem; 30373485
    Objectives: To evaluate the magnetic resonance imaging (MRI)-derived parameters in differentiation of patients with progressive supranuclear palsy (PSP) from patients with Parkinson's disease (PD), multiple system atrophy (MSA), and control subjects was aimed. Methods: Thirty-three patients [mean age, 65.21 +/- 4.75 years; PSP (n = 9), MSA (n = 8), PD (n = 6), and control subjects (n = 10)] who have undergone cranial MRI were included in this retrospective study. MRI-derived parameters including areas of midbrain and pons, midbrain area-to-pons area (M/P) ratio, widths of middle cerebellar peduncle (MCP) and superior cerebellar peduncle (SCP), MCP/SCP ratio, magnetic resonance parkinsonism index (MRPI), cerebral interpeduncular angle, and length of midbrain tegmentum were compared in patients with PSP, PD, MSA, and control subjects through the analysis of variance and Kruskal-Wallis tests with Bonferroni correction and Mann-Whitney U test. Results: The length of midbrain tegmentum, midbrain area, SCP, and M/P ratio were found to be lower, while cerebral interpeduncular angle and MRPI were higher in patients with PSP. Pons area, MCP width, and MCP/SCP ratio were found to be lower in patients with MSA. For PSP, cerebral interpeduncular angle has a sensitivity of 100% and specifity of 90%, and MRPI had a sensitivity of 88.9% and specifity of 100% for PSP. Discussion: Several MRI-derived parameters can be used in differentiation of patients with PSP from patients with PD, MSA and control subjects. The cerebral interpeduncular angle and MRPI, which demonstrated higher values in patients with PSP, were more significant for PSP than the other parameters.

    (2019) Aydin, Elcin; Altin, Cihan; Soylev, Gozde Ozcan; Tekindal, Mustafa Agah; Agildere, Muhtesem; 30300321; AAB-5802-2020
    Purpose Patients with vitamin D deficiency (VDD) have potential to have increased cardiovascular morbidity and mortality. In this study, we aimed to discover the findings of early atherosclerosis in patients with VDD by measuring carotid intima-media thickness (CIMT) and epicardial fat thickness (EFT). Materials and Methods The study population includes 52 patients with VDD (n = 30 [57% female], mean +/- SD age 54.28 +/- 8.77 years, mean +/- SD serum 25-hydroxyvitamin D (25 [OH] D) 11 +/- 2.4 ng/mL) and 82 participants for control group (n = 52 [63.4% female], mean +/- SD age 56.40 +/- 7.90 years, mean +/- SD serum (25 [OH] D) 53 +/- 4.2 ng/mL) who have no cardiovascular disease. Carotid intima-media thickness was assessed by using ultrasonography, and EFT was measured on the free wall of the right ventricle at end diastole from the parasternal long-axis views by standard transthoracic 2-dimensional echocardiography. Results Both CIMT and EFT were significantly higher in patients with VDD compared with controls (0.75 +/- 0.16 mm vs 0.68 +/- 0.21 mm, P < 0.05, and 0.66 +/- 0.15 cm vs 0.56 +/- 0.15 cm, P < 0.001). Conclusions Patients with VDD seem to have increased CIMT and EFT, which are predictors of atherosclerotic process. Further studies are needed to confirm these results.

    One of the Rare Causes of Acute Abdomen Leading to Subileus: Jejunal Diverticulitis
    (2016) Aydin, Elcin; Yerli, Hasan; Avci, Tevfik; Yilmaz, Tugbahan; Gulay, Huseyin; 27308082
    Background: Jejunal diverticulitis is one of the rare causes of acute abdomen generally seen in the elderly. Jejunal diverticulosis was defined as the herniation of the mucosa and the submucosa from the inside of the muscular layer of the bowel wall on the mesenteric side of the intestine. Case Report: We presented the intraoperative and pathological findings of a 69-year-old male patient who had presented with complaints about abdominal pain, nausea, and vomiting and been operated upon due to subileus and peritonitis induced by large-sized jejunal diverticulitis, along with his computed tomography (CT) findings. Conclusion: Jejunal diverticulitis is uncommon and may be a disease which might be difficult to diagnose when it develops on the basis of the large-sized diverticula resembling intestinal ansae. To the best of our knowledge, the computed tomography and intraoperative findings of a case in which partial resection is applied to the jejunum due to subileus have not been previously presented in the literature.

    Temporal Lobe Parenchyma Herniation into the Transverse Sinus: MRI Findings in a Case
    (2016) Aydin, Elcin; Yerli, Hasan; Gezmis, Esin; 0000-0002-1001-6028; 0000-0003-2463-1758; 0000-0003-0907-3647; 30151437; AAE-8301-2021; AAK-9572-2021; AAI-8276-2021
    Brain parenchyma herniation into dural venous sinus which is a uncommon entity, can cause dural venous sinus filling and simulate sinus thrombosis and other pathologies. It is isointense to brain parenchyma on all sequences by magnetic resonance imaging, surrounded by a cerebrospinal fluid rim and is seen to be contiguous with brain tissue on images. We report a rare case with spontaneous occult herniation of temporal lobe tissue into the left transverse sinus that may associated with headache.

    (2016) Aydin, Elcin; Coban, Gokcen; Coskunoglu, Esra Zeynep; Tukenmez, Mehmet; 0000-0003-0907-3647; 0000-0003-4824-4138; 30151458; AAI-8276-2021; AAJ-6774-2021
    Vascular leiomyomas or angioleiomyomas are rare benign solitary smooth muscle tumors that origin usually in the extremities. Most of these tumors are composed of venous vessels. Here in, we report a rare case of subcutaneous vascular leiomyoma of the right knee of a 38 year old woman who was presented with recurrent anterior right knee pain and soft tissue swelling. Clinical findings, magnetic resonance imaging and histopathologic findings of the tumor is discussed. Leiomyomas are not mostly considered in the differential diagnosis by radiologist due to its rarity. Typical imaging and clinical findings of a tumor is an important clue for an accurate and early diagnosis.

    (2018) Aydin, Elcin; Gok, Mustafa; Esenkaya, Asim; Cinar, Celal; Oran, Ismail; 0000-0003-0907-3647; 27593845; AAI-8276-2021
    AIM: To evaluate iatrogenic vascular injuries in the craniocervical region and their endovascular management. MATERIAL AND METHODS: Twenty-one patients (9 women, 12 men) with a mean age of 53.6 years (range 16-87 years), who underwent endovascular embolization for iatrogenic vascular injury in the craniocervical region between December 2000 and October 2015, were included in this retrospective study. Types of iatrogenic injuries, etiologies that caused these injuries and details of endovascular managements were reported. RESULTS: The etiologies of the vascular injuries were as follows: transsphenoidal surgery (n=9), skull-base surgery (n=2), cholesteatoma surgery (n=1), tracheostomy (n=2), central venous catheterization (n=2), oropharyngeal tumor operation (n=1), endovascular treatment of internal carotid artery (ICA) stenosis (n=1), suprasellar epidermoid tumor operation (n=1), sphenoid sinus tumor surgery (n=1), and speech prosthesis device placement (n=1). The types of vascular injuries diagnosed at the time of angiography were; 2 occlusions, 2 stenoses, 2 dissections, 1 carotid cavernous fistula, 8 artery rupture with extravasation, and 9 pseudoaneurysms. Endovascular management of these vascular injuries were; parent artery occlusion (PAO) (n=15), aneurysm occlusion (n=3), covered stent (n=1) and conservative management (n=2). All patients except two were successfully treated. No patient had bleeding within a 30-day period after angiography. Long-term follow-up was available in all patients without occurrence of re-bleeding. One patient died due to complications related to primary vascular injury. CONCLUSION: Although iatrogenic vascular injuries are rare, early diagnosis and management may be lifesaving. Endovascular techniques are reliable and safe in most of the patients.

    Eagle Syndrome Presenting with Neurological Symptoms
    (2018) Aydin, Elcin; Quliyev, Huseyin; Cinar, Celal; Bozkaya, Halil; Oran, Ismail; AAI-8276-2021; 0000-0003-0907-3647; 27858390
    AIM: Eagle syndrome is a rare entity that causes recurrent throat pain, neck pain, dysphagia, or facial pain due to an elongated styloid process or calcified stylohyoid ligament. Clinical findings related to lower cranial nerve compression have also been reported. In some cases, it is reported that carotid artery compression or dissection can be seen due to elongated styloid process and this is called carotid artery syndrome. Carotid artery compression causes flow reduction and carotidynia or neurological symptoms can be seen. Dural sinuses and the jugular vein can be compressed. Eagle syndrome with neurological symptoms has been rarely reported. MATERIAL and METHODS: The data of 5 patients (aged between 22 and 68 years), who presented to the hospital with various neurological symptoms, were retrospectively reviewed. Each patient underwent computed tomography (CT) that revealed a long styloid process. RESULTS: An elongated styloid process caused neurological symptoms. Two patients had venous compression by the styloid process and the other patients had transient ischemic attacks due to internal carotid artery compression by the styloid process. Only one patient underwent surgical removal. All patients' outcomes were good after treatment and no symptoms remained. CONCLUSION: Eagle syndrome may be presented with neurological symptoms. It should be kept in mind in the differential diagnosis of patients who have neurological symptoms without any objective etiological factors. To the best of our knowledge, Eagle syndrome with arterial and venous compression due to elongated styloid process has not been previously presented in the literature.
