Mean survival has been reported as 6-11 months. Despite the optimal treatment is unclear surgery, chemotherapy and radiotherapy are the well known treatment options. We would like to report a 4 year old boy who had the diagnosis of ATRT at the temporooccipital region to make a contribution to the literature.Publication Nasolacrimal canal morphology with or without idiopathic obstruction in caucasian adults: A multidetector ct study(Springer, 2022-01-26) Ulutaş, Hafize Gökben; Yazıcı, Bülent; Yazıcı, Zeynep; YAZICI, ZEYNEP; Ulutaş, Emin; Tıp Fakültesi; Radyoloji Ana Bilim Dalı; 0000-0001-8889-1933; AAA-5384-2020; JLL-3176-2023Purpose To compare the morphological features of the bony nasolacrimal canal (NLC) in Caucasian adults with and without primary acquired nasolacrimal duct obstruction (PANDO). Methods The study included one eye each from 38 patients with PANDO and 38 age- and gender-matched controls without PANDO, all of whom underwent multidetector computed tomography. In tomographic images, length, and orientation angles of the NLC, transverse canal diameters at the duct entrance and lower end, and minimum (narrowest) transverse and anterior-posterior canal diameters were measured. Results The two groups were similar for NLC length and angulations. The transverse entrance diameter was significantly narrower in the PANDO group (mean, 4.6 mm vs. 5.1 mm) (p = 0.09). The narrowest site was most frequently in the middle duct or slightly above the middle in both groups (p > 0.05). The minimum canal diameters were significantly smaller in the PANDO group (p = 0.010 and p = 0.003). When gender subgroups were compared, the significant differences continued for the transverse entrance and minimum diameters in females with PANDO (p = 0.006) and for the minimum anterior-posterior diameter in males with PANDO (p = 0.02). Conclusion Narrowness of the upper and/or middle part of the bony nasolacrimal duct may play a role in the development of PANDO in the adult Caucasian population.Publication Malignant transformation of monostotic fibrous dysplasia into angiosarcoma in the proximal tibia(Wolters Kluwer Medknow Publications, 2021-04-01) Yalçınkaya, Ulviye; YALÇINKAYA, ÜLVİYE; Narter, Selin; NARTER, SELİN; Bilgen, Muhammet S.; BİLGEN, MÜHAMMET SADIK; Yazıcı, Zeynep; YAZICI, ZEYNEP; Tıp Fakültesi; Ortopedi Ana Bilim DalıThe majority of bone angiosarcomas are primary tumors while secondary angiosarcomas arise after radiation therapy or bone infarctus. This article presents a case of malignant transformation of monostotic fibrous dysplasia into angiosarcoma. An 80-year-old female presented with pain on right cruris. Radiological examination revealed a lesion with lytic areas and destruction of cortical bone on right tibia. Gross and histopathological examination showed two areas with an abrupt transition. The solid component was composed of curved, immature bony trabeculae in a fibroblastic stroma. The other component involved epitheloid cells forming slit-like vascular spaces. The diagnosis of angiosarcoma and fibrous dysplasia was given. Malignant transformation of fibrous dysplasia into angiosarcoma is extremely rare; as this is the sixth case in the existing literature. Prognosis of fibrous dysplasia is generally good and less than 1% of the patients develop a malignant tumor. Therefore, patients with fibrous dysplasia should be offered a life-long follow-up.Publication Two cases diagnosed with tuberosclerosis in neonatal period(Galenos Yayıncılık, 2014-12-01) Varal, İpek Güney; Köksal, Nilgün; Özkan, Hilal; Bostan, Özlem; Bağcı, Onur; Uysal, Fahrettin; Yazıcı, Zeynep; Doğan, Pelin; Varal, İpek Güney; Köksal, Nilgün; BOSTAN, ÖZLEM MEHTAP; ÖZKAN, HİLAL; Bağcı, Onur; UYSAL, FAHRETTİN; YAZICI, ZEYNEP; Doğan, Pelin; Tıp Fakültesi; Radyoloji Ana Bilim Dalı; Pediatrik Radyoloji Bilim Dalı; 0000-0001-7707-2174; 0000-0001-9308-9806; CIR-8129-2022; JGS-7600-2023; JJY-3921-2023; AAG-8558-2021; KYP-5736-2024; AAH-4421-2021; AAI-2303-2021; CNZ-3688-2022Congenital heart tumors are very rare and the most common type is the rhabdomyoma. Frequency during autopsy is between 0.027-0.08%. Moreover 51-86% of these tumors are associated with tuberosclerosis. Also hamartomas might accompany, particularly on the central nervous system and skin, kidney, liver, lung and heart. In this paper, two cases diagnosed with tuberculosis who showed rhabdomyomas in fetal echocardiography in the antenatal period and were seen to have tubers in cranial magnetic resonance (MR) postnatally, are presented.Publication Radiation exposure in the neonatal intensive care unit in newborns and staff(Thieme Medical Publ Inc, 2021-07-28) Çakır, Salih Çağrı; Dorum, Bayram Ali; Köksal, Nilgün; Özkan, Hilal; Yazıcı, Zeynep; Parlak, Müfit; Gülleroğlu, Nadide Başak; ÇAKIR, SALİH ÇAĞRI; Dorum, Bayram Ali; Köksal, Nilgün; ÖZKAN, HİLAL; YAZICI, ZEYNEP; PARLAK, MÜFİT; Gülleroğlu, Nadide Başak; Tıp Fakültesi; Pediat Bölümü; 0000-0001-5761-4757; 0000-0002-2823-8454; HJZ-4508-2023; AEZ-2469-2022; A-5375-2017; A-5375-2017; CZV-1969-2022; IGT-7005-2023; AAI-2303-2021; AAG-8521-2021; EZQ-1350-2022Objective Portable X-rays remain one of the most frequently used diagnostic procedures in neonatal intensive care units (NICU). Premature infants are more sensitive to radiation-induced harmful effects. Dangers from diagnostic radiation can occur with stochastic effects. We aimed to determine the radiation exposure in premature infants and staff and determine the scattering during X-ray examinations in the NICU. Study Design In this prospective study, dosimeters were placed on premature infants who were <= 1,250 g at birth and <= 30 weeks of gestational age who stayed in the NICU for at least 4 weeks. The doses were measured at each X-ray examination during their stay. The measurements of the nurses and the doctors in the NICU were also performed with dosimeters over the 1-month period. Other dosimeters were placed in certain areas outside the incubator and the results were obtained after 1 month. Results The mean radiation exposure of the 10 premature infants, monitored with dosimeters, was 3.65 +/- 2.44 mGy. The mean skin dose of the six staff was 0.087 +/- 0.0998 mSV. The mean scattered dose was 67.9 +/- 26.5 mu Gy. Conclusion Relatively high exposures were observed in 90% of the patients and two staff. The radiation exposure levels of premature infants and staff may need to be monitored continuously.Publication X-ray-evaluation(Aves Yayincilik, Ibrahim Kara, 2008-03-01) Hacımustafaoğlu, Mustafa; HACIMUSTAFAOĞLU, MUSTAFA KEMAL; Çelebi, Solmaz; ÇELEBİ, SOLMAZ; Yazıcı, Zeynep; YAZICI, ZEYNEP; Tıp Fakültesi; Radyoloji Ana Bilim Dalı; 0000-0003-4646-660X; AAI-2303-2021Publication Clinical clues(Aves Yayincilik, Ibrahim Kara, 2012-09-01) Gurpinar, Arif; GÜRPINAR, ARİF NURİ; Yazici, Zeynep; YAZICI, ZEYNEP; Celebi, Solmaz; ÇELEBİ, SOLMAZ; Hacimustafaoglu, Mustafa; HACIMUSTAFAOĞLU, MUSTAFA KEMAL; Tıp Fakültesi; Çocuk Cerrahi Ana Bilim Dalı; 0000-0003-4646-660X; AAI-2303-2021Publication X-ray-evaluation(Aves Yayincilik, Ibrahim Kara, 2011-09-01) Hacımustafaoglu, Mustafa; ÇELEBİ, SOLMAZ; HACIMUSTAFAOĞLU, MUSTAFA KEMAL; Çelebi, Solmaz; YAZICI, ZEYNEP; Yazıcı, Zeynep; Tıp Fakültesi; Çocuk Sağlığı ve Hastalıkları Ana Bilim Dalı; 0000-0003-4646-660X; AAI-2303-2021Publication Pediatric multilocular cystic nephroma extending into the renal pelvis and ureter(Galenos Yayıncılık, 2014-11-01) Doğan, Hasan Serkan; Yazıcı, Zeynep; Aytac, Berna; Sevinir, Betül; Erdoğan, Hakan; Çiçek, Çağatay; YAZICI, ZEYNEP; AYTAÇ VURUŞKAN, BERNA; SEVİNİR, BETÜL BERRİN; ÇİÇEK, MEHMET ÇAĞATAY; Tıp Fakültesi; Üroloji Ana Bilim Dalı; AAH-1570-2021; AAI-2303-2021; AAH-9746-2021; JLG-1312-2023Multilocular cystic nephroma (MCN) is a rare tumor at the most benign end of the spectrum of the multilocular cystic neplasms of kidney. Nephrectomy is curative for MCN. In this case-report, we present a 16-month-old girl with a 10x15 cm multilocular cystic renal tumor extending into the renal pelvis and proximal ureter on the right side demonstrated on magnetic resonance imaging. Nephrectomy was performed. The pathology was completely consistent with MCN.Publication Preoperative endovascular embolization of orbital solitary fibrous tumor with 500-700 micron tris-acryl gelatin microspheres(Galenos Publ House, 2022-10-01) Muz, Ömer Ersin; Yazıcı, Bülent; Hakyemez, Bahattin; HAKYEMEZ, BAHATTİN; Yazıcı, Zeynep; YAZICI, ZEYNEP; Yalcinkaya, Ulviye; YALÇINKAYA, ÜLVİYE; Tıp Fakültesi; Patoloji Ana Bilim Dalı; 0000-0001-8889-1933; AAA-5384-2020; AAI-2318-2021; AAH-8924-2021; AAA-5384-2020; AAI-2303-2021The reported experience with preoperative embolization of solid orbital tumors is scarce. Herein, we present a case of a large and hypervascular orbital solitary fibrous tumor (SFT) in which 500-700 mu m tris-acryl gelatin microspheres (TAGM) were used for preoperative embolization. A 41-year-old man presented with severe proptosis, palpable mass, restrictive myopathy, exposure keratopathy, and compressive optic neuropathy in the right orbit. Magnetic resonance imaging showed a 65x35x35 mm, diffusely contrast-enhanced tumor in the superior orbit, extending to the apex, and multiple intratumoral vascular flow voids. A diagnosis of SFT was made by incisional biopsy. Endovascular tumor embolization was performed with 500-700 mu m TAGM. Two days later, the tumor was entirely removed with minimal bleeding. No embolization-or surgery-related complications and tumor recurrence or metastasis developed during the 42-month postoperative follow-up.
