Publication Cerebral hydatid cyst with intraventricular extension: A case report(Oxford Univ Press, 2019-12-01) Cingöz, Mehmet; Olmaz, Burak; Akdoğan, Emin; Cengiz, Mustafa; Kandemirli, Sedat Giray; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Radyoloji Anabilim Dalı.; A-1409-2017Intracranial hydatid cyst is a rare entity, comprising about 2-3% of all hydatid cysts. Similarly, intracranial hydatid cysts account for 1-2% of all intracranial lesions. Clinical symptoms are generally nonspecific and patients usually present with symptoms of increased intracranial pressure. Cerebral hydatid cysts can be either primary or secondary to systemic hydatid disease. Primary cerebral hydatid cysts are usually solitary, unilocular with an intraparenchymal location. Intraventricular extension of hydatid cysts account for a limited percentage of all cerebral hydatid cysts with limited number of cases reported. Herein, we present the imaging and surgical findings of a primary cerebral hydatid cyst that is located in frontal lobe parenchyma with partial extension into the ventricular system.Publication Correlation of imaging and intraoperative findings in Pott's puffy tumour(Sage, 2019-02-01) Olmaz, Burak; Cingöz, Mehmet; Akdogan, Emin; Kandemirli, Sedat G.; Kandemirli, Sedat G.; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Radyoloji Anabilim Dalı; 0000-0002-3976-4062; A-1409-2017Introduction Pott's puffy tumour is characterised by frontal bone osteomyelitis accompanied by subperiosteal abscess. It can be further complicated by intracranial extension of the infectious process. Case presentation A 12-year-old boy initially presented with signs and imaging findings of pan-sinusitis. Despite antibiotic therapy, there was progressive swelling of the forehead region. Subsequent imaging studies revealed osteomyelitis of frontal bone, subcutaneous abscess and extension into intracranial space. The abscesses were surgically drained, and craniectomy for osteomyelitis was carried out. Conclusion The initial symptoms of Pott's puffy tumour can be subtle, and antibiotic use may mask the underlying sinister involvement of intracranial structures. Imaging plays an important role both in diagnosis and detection of possible intracranial complications.Item Temporal evolution of imaging findings in ossified cephalohematoma(Lippincott Williams & Wilkins, 2019-12-23) Cingöz, Mehmet; Olmaz, Burak; Kandemirli, Sedat Giray; Bilgin, Cem; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Radyoloji Anabilim Dalı.; FEP-7016-2022; CFR-0325-2022; 22834938400; 57200617643Background: Cephalohematoma is collection of blood between skull and periosteum that is confined by cranial sutures. Cephalohematomas usually resorb spontaneously within the first month of life; however, if it fails to resolve, ossified cephalohematoma may form. Methods: Clinical archiving system and picture archiving and communication system were retrospectively reviewed for cases of birth-related cephalohematoma. Cases of ossified cephalohematomas identified on imaging were retrieved from this subset of patients. Cross-sectional imaging findings in patients with ossified cephalohematomas were evaluated for location, size of the hematoma, and contours of the inner lamella. Results: Out of 115 cases of cephalohematoma, 7 cases had imaging findings consistent with ossified cephalohematoma. All ossified cephalohematomas were located parietally, with size ranging between 18 and 55 mm and the thickness of the outer rim of calcification ranging between 1.5 and 4.8 mm. The contour of inner lamella in relation to the surrounding normal cranial vault was normal in 5 cases, and inner lamella was depressed in 2 cases. Three patients had follow-up imaging available for demonstration of changes in ossified cephalohematoma. The first case was an 11 day-old boy with a cephalohematoma with no signs of calcification at the time of initial imaging. Follow-up at 2 months of age showed partial regression of hematoma cavity with marked calcification at the hematoma walls. The second case was a 3 month-old boy with ossified cephalohematoma at initial imaging. Follow-up imaging at 7 months of age showed almost total regression of hematoma cavity, and approximation of inner and outer lamella with increased thickness of the cranial vault. The third case was a 1 month-old boy with ossified cephalohematoma at initial imaging that totally resolved without residual increased bone thickness at 21-month follow-up. Conclusion: These 3 cases demonstrate the variability in temporal changes that may occur in ossified cephalohematomas.
