Item Management of MRI-Detected Benign Internal Mammary Lymph Nodes(2022) Gunes, Gozde; Crivellaro, Priscila; Muradali, Derek; 0000-0003-0991-1380; 35924122; G-4374-2017Introduction In this retrospective study, we aimed to evaluate benign internal mammary lymph nodes (IMLNs) in terms of frequency, number, size, long axis/short axis (L/S) ratio, intercostal location, presence of fatty hilum, and stability using breast magnetic resonance imaging (MRI) and discuss the findings by reviewing existing literature. Methods This single-center study consisted of 130 women between the ages of 24 and 76 years, who had at least two breast MRI examinations in our institution, with the latest exam performed between January 1, 2019 and November 1, 2019, were eligible for the study. MRIs of the study group were independently reviewed by two radiologists. Results IMLN was detected in 31.1% of the 427 MRIs, with a total number of 256 nodes. The most common indication for breast MRI was high-risk screening (66.2%). The median number of nodes per patient was 1 (range: 1-6). The median follow-up time was 19.5 months (range: 6-141 months). None of these benign nodes showed significant interval growth. Mean L/R ratio of the nodes was 1.9. One hundred and four nodes (n = 104, 40.6%) had a L/S ratio less than 2 and 43.2% (n = 45) of the nodes with a L/S ratio less than 2, had a long axis measuring less than or equal to 3mm. IMLN of patients with breast implants had the largest mean long axis. The fatty hilum was identified in 34.3% (n = 68) of the 256 nodes. The size of the lymph nodes where fatty hilum was visualized was significantly larger than the ones where fatty hilum was not visualized (p < 0.001). Fatty hilum could be visualized in only 2.7% of the nodes with a long axis smaller than 3 mm. Conclusion IMLN is a frequent finding on breast MRI. We have shown that benign IMLNs might be large sized in specific cases like patients with breast implants. When small sized (<= 3mm), they are more likely to be rounded (1/S ratio <2). The fatty hilum that is a feature of benignity might not be visualized in nodes less than or equal to3mm.Item Bilateral renal leiomyoma with 5 year follow-up: Case report(2015) Goren, Mehmet Resit; Erbay, Gurcan; Ozer, Cevahir; Goren, Vinil; Bal, Nebil; 26664510Renal leiomyomas are exceptionally rare benign tumours of the kidney. Although the renal leiomyomas usually do not metastasize, the differential diagnosis between renal leiomyomas and malign lesions (leiomyosarcoma or renal cell carcinoma) cannot be done by radiological examinations, but is possible by histological examination. Surgery is the preferred treatment. After surgery, the prognosis is excellent without recurrence. Although uterine leiomyomas can be multicentric, renal leiomyomas have been single lesions. We report an incidentally detected case of bilateral renal leiomyoma in a 50-year-old woman with a 5-year follow-up. We also review the literature and discuss clinical, radiological and histological features of renal leiomyomas.Item 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-8276-2021Brain 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.Item Vascular Leiomyoma Presenting as Anterior Knee Pain (Case Report)(2016) Aydin, Elcin; Coban, Gokcen; Coskunoglu, Esra Zeynep; Tukenmez, Mehmet; 0000-0003-0907-3647; 0000-0003-4824-4138; 30151458; AAI-8276-2021; AAJ-6774-2021Vascular 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.
