In this report, we present a patient with subdural empyema, brain abscess, and superior sagittal cerebral venous thrombosis as complications of rhinosinusitis whose purulent empyema sample yielded S. anginosus. A 13-year-old female patient was referred to our pediatric intensive care unit with altered mental status, aphasia, and behavioral change. On a brain computed tomography scan, subdural empyema extending from the left frontal sinus to the frontal interhemispheric area and left hemispheric dura was detected. Intravenous ceftriaxone, vancomycin, and metronidazole treatments were started. Subdural empyema was surgically drained. Postoperative brain magnetic resonance venography imaging showed superior sagittal sinus thrombosis. Cultures obtained from purulent empyema sample revealed S. anginosus. On the third day of hospitalization, a brain computed tomography scan showed brain edema, especially in the left hemisphere and significantly increased subdural empyema that had been previously drained. She was reoperated and decompressive craniectomy was performed. On the fifth day, partial epileptic seizures occurred. Brain magnetic resonance imaging showed a brain abscess on the interhemispheric area. The magnetic resonance imaging findings of abscess formation improved on 30th day and she was discharged on the 45th day after the completion of antibiotic therapy.Publication Metadata only A Rare Presentation of Neurobrucellosis in a 6-Year-Old Pediatric Patient with Sagittal Sinus Thrombosis(2020-10-01T00:00:00Z) TÜREL, Özden; KUTLU, NURETTİN ONUR; YEŞİLBAŞ, Osman; Yozgat, Can Yilmaz; DÜNDAR, TOLGA TURAN; BURSAL DURAMAZ, BURCU; UZUNER, SELÇUK; ABDİLLAHİ, FATOUMA KHALİF; TÜREL, ÖZDEN; UZUNER, SELÇUK; BURSAL DURAMAZ, BURCU; DÜNDAR, TOLGA TURAN; SEYİTHANOĞLU, MEHMET HAKAN; YEŞİLBAŞ, OSMAN; KUTLU, NURETTİN ONURBrucellosis is one of the most common zoonosis worldwide. It is still endemic in many regions of the world. A 6-year-old female was admitted to the emergency department (ED) due to a sudden change in consciousness, urinary incontinence, vomiting, and difficulty in walking. Neurological examination demonstrated abducens nerve paralysis, mild-to-moderate motor deficit in hemiparesis in the left arm. Brain magnetic resonance imaging showed a hemorrhagic focus at the right frontal lobe and thrombosis in the superior sagittal sinus of the brain. The diagnosis of neurobrucellosis was confirmed by identifying Brucella spp. in the blood culture on the day 6 of pediatric intensive care unit admission; thus, trimethoprim-sulfamethoxazole and rifampicin, and ceftriaxone were promptly initiated. Despite neuroprotective management and acetazolamide, the patient-s neurological problems and high intracranial pressure (ICP) persisted. An external ventricular drainage tube and a Codman ICP monitor were placed to be on the consent vigilance of the patient-s neurological condition. The patient-s ICP continued to increase despite the current treatment regimen; therefore, a decompressive bitemporal craniectomy was performed. The ICP level of the patient returned to its normal range immediately after the craniectomy. The patient did not have any notable neurologic sequelae at the first-year follow-up. Neurobrucellosis is a rare complication of systemic brucellosis and may present as meningitis, encephalitis, myelitis, radiculitis, and/or neuritis. Herein, we describe a six-year-old girl with brucellosis complicated with cerebral vein thrombosis. This case illustrates the need for close monitoring of patients with unexplained neurological signs or symptoms for brucellosis in endemic areas.Publication Metadata only Williams Syndrome Presenting with Intractable Staphylococcus aureus Endocarditis(2020-02-14T04:00:00Z) Yozgat, Can Yilmaz; UZUNER, SELÇUK; Yesilbas, Osman; BURSAL DURAMAZ, BURCU; YOZGAT, Yılmaz; İŞCAN, AKIN; TÜREL, Özden; UZUNER, SELÇUK; YEŞİLBAŞ, OSMAN; BURSAL DURAMAZ, BURCU; YOZGAT, YILMAZ; İŞCAN, AKIN; TÜREL, ÖZDENPublication Metadata only Multiple Brain Abscesses Due to Actinomyces Odontolyticus: A Rare Infection In a Previously Healthy Child(2019-11-01T00:00:00Z) Oztanir, Mustafa Namik; SARITAŞ, BETÜL; Duramaz, Burca Bursal; YEŞİLBAŞ, Osman; Nizam, Oznur Gokce; TEKİN, Abdurrahim; TÜREL, Özden; BARIŞ, SAFA; SARITAŞ, BETÜL; YEŞİLBAŞ, OSMAN; ÖZTANIR, MUSTAFA NAMIK; TEKİN, ABDURRAHIM; TÜREL, ÖZDEN
