Abstract
OBJECTIVE To determine the preoperative MRI findings of patients with breast cancer according to molecular subtypes. MATERIALS AND METHODS MRI findings of women diagnosed with breast cancer in our department between January 2013 and June 2017 who had preoperative breast MRI examinations were evaluated and histopathological findings were recorded retrospectively. The findings were classified according to the BI-RADS MRI classification by three radiologists. Correlations of MRI findings with the molecular subtypes were evaluated using Chi-square and t-tests. RESULTS Among 234 lesions in a total of 224 cases diagnosed with breast cancer, subtypes of breast cancer as following: Luminal (162 cases, 69%), triple negative (39 cases, 17%) and HER2 positive (33 cases, 14%), respectively. Lesions of patients with luminal, triple negative and HER2 positive invasive ductal cancer were round or lobular in shape (9.9%, 42.9%, 20.7%), had high/very high intratumoral T2 signal intensity (24.8%, 54.2%, 31%) and rim enhancement pattern (9.2%, 51.4%, 24.1%), respectively. The difference between the triple negative cases and the other subtypes was statistically significant (p < 0.05). CONCLUSION One of the most important factors that determine the prognosis and treatment in breast cancer is the molecular subtype of the tumor. Morphologic findings of MRI can be a useful tool for differentiating triple negative breast cancer from other subtypes.

Abstract
Basosquamous carcinoma of the skin is a rare malignancy with specific histopathological features of both basal cell carcinoma and squamous cell carcinoma. Some authors believe that basosquamous carcinoma is a variant of basal cell carcinoma, while others suggest that this tumour may behave more aggressively. We present a 44-year-old female patient who was diagnosed with a basosquamous carcinoma histopathologically. She had extensive ulcero-vegetative lesions, involving the anterior half of the scalp, the left orbit and the left side of the face. With this case we aim to emphasize the aggressive nature of basosquamous carcinoma and review the literature.

Abstract
Henoch-Schönlein purpura, although being a systemic vasculitis, mostly involves skin, gastrointestinal system, joints, and kidneys. Testicular involvement is a rare occurrence. A 7-year-old boy with Henoch-Schönlein purpura developed acute scrotum and was referred to rule out testicular torsion. On gray-scale ultrasonography, the testes and epididymis were slightly enlarged, and had heterogeneous and hypoechoic echotexture. The scrotal wall was thickened as well. Color and power Doppler ultrasonography revealed increased vascularity in scrotal contents. Testicular torsion was excluded and the diagnosis of testicular involvement of Henoch-Schönlein purpura was established. Color Doppler US, together with gray-scale findings, can be useful in the evaluation of Henoch-Schönlein purpura with acute scrotum, excluding testicular torsion and preventing unnecessary surgery.

Abstract
The purpose of this prospective study was to evaluate the value of power Doppler ultrasonography (PDUS) in assessing the vascularity of skin tumors other than malignant melanoma, and to investigate possible diagnostic criteria to help to distinguish malignant from benign tumors preoperatively. Seventy-one patients with the clinical diagnosis of a skin tumor were initially evaluated by ultrasonography. Then PDUS was performed and the presence and type of vascularity (peripheral or mixed) were investigated. Of the 19 benign and 52 malignant lesions, 3 could not be visualized with US. Forty-nine lesions were found to have vascularity (21 peripheral, 28 mixed-type) on PDUS. Of the malignant lesions, 26 showed mixed and 17 showed peripheral-type vascularity; for benign lesions these numbers were 2 and 4 respectively. The presence of vascularity correlated well with pathological behavior (malignant versus benign) (P = 0.00002), width (P = 0.0001), thickness (P = 0.001), dermal disruption (P = 0.0018), and subdermal extension (P = 0.002) of the tumor; however, the type of vascularity correlated only with thickness (P = 0.014). In relation to malignancy, the sensitivity of the presence of vascularity on PDUS was 88% and the specificity was 63%. These values were 93% and 40% respectively, for the mixed type of vascularity when it was accepted as a feature of malignancy. PDUS may help to distinguish malignant from benign skin tumors during preoperative evaluation.

Abstract
The purpose of this study is to determine important variations and areas of risk for major complications in paranasal computed tomography (CT). We also made specific measurements for individual differences. This study consisted of 64 children (128 sides). Eleven participants had coronal and axial, and the remaining 53 only coronal CT. The distance of the anterior ethmoidal artery (AEA) and the lamina cribrosa to the inferior turbinate and the orbital roof, and the depth of the lamina cribrosa were measured. The percentages of some of the variations were as follows: upper attachment of uncinate process 25%, freely coursing AEA 43%, aerated anterior clinoids 8%, optic canal bulging 6% and extreme medially coursing carotid canal 3%. The frequencies of some of these variations and the existence of Onodi cells were significantly smaller than compared with adults. Specific measurements varied individually. In conclusion, children deserve more attention while evaluating CT, due to their tiny bony structures.

Abstract
BACKGROUND The diagnostic value of Doppler US in infectious disease of the kidney is well documented. Previous studies have demonstrated high resistive indices, especially in tubulo-interstitial diseases. OBJECTIVE To evaluate the role of intrarenal colour duplex Doppler US in lower urinary tract infections (UTI). MATERIALS AND METHODS This prospective study was carried out in 111 children (222 kidneys) (age range 1-180 months). Of the children, 78 were healthy while 33 presented with lower UTI. The resistive indices (RI) were measured from the spectral waveforms obtained from interlobar arteries. RESULTS No statistically significant difference was found between RI of right and left kidneys in both groups. The mean RI was 0.75 +/- 0.07 in patients with lower UTI and 0.71 +/- 0.1 in the control group (P < 0.05). In the control group there was an inverse correlation between age and RI (P < 0.05). CONCLUSIONS High RI may be found in lower UTI.

Abstract
Antrochoanal polyps (ACP) represent 4-6% of all nasal polyps in the general population, but this proportion increases to 33% in the pediatric group. The aim of this study is to discuss clinical and radiological findings, and some different surgical approaches with their results in the pediatric patients. This study consists of eight children with ACP diagnosed by means of clinical examination, nasal endoscopy and computed tomography. One patient was treated only with simple polypectomy. In five patients, transcanine sinuscopy (TS) was added to functional endoscopic sinus surgery. Four of the patients underwent anterior ethmoidectomy and uncinectomy. Middle meatal antrostomy was applied to two of them. No recurrence was encountered within 5-30 months. The decision for the appropriate type of surgery for ACP is influenced by factors such as patient's age, other accompanying sinus pathologies, recurrence after previous surgery, and the possibility of total excision. In patients carrying the risk of recurrence, it is especially important to remove the polyp completely and manage other sinus pathologies, as well as avoiding an unnecessarily expanded operation. In selected patients, we believe that TS may be adequate in totally removing ACP.

Abstract
The purpose of this study is to determine some important variations and dangerous areas carrying risks for major complications, in the routine CT examination. We also made specific measurements to evaluate the individual differences. This prospective study consisted of 111 patients (222 sides). Eighty patients underwent coronal, and the rest coronal and axial CT. The depth of lamina cribrosa, its distance to the inferior turbinate, and the distance of anterior ethmoidal artery (AEA) either to the orbital roof or inferior turbinate were measured. Variations of the upper attachment of uncinate process were encountered in 23%. AEA coursed freely within ethmoidal cells in 43%. Anterior clinoid aeration was seen in 14%, optic canal bulging into the sphenoid sinus in 13% and an extreme medial course of the carotid canal in 12% of the patients. The mean depth of lamina cribrosa was 5.9 mm, and its mean distance to the inferior turbinate was 25.7 mm. The mean distance of AEA to the orbital roof was 13.7 mm, and to the inferior turbinate 30.05 mm. Anterior clinoid aeration correlated well with the variations of carotid and optic canals, statistically (p < 0.01). A detailed CT study will provide important information on the areas carrying risks of complications and the size of the area to be worked on.
