ZusammenfassungWir stellen den Fall eines 7-jährigen Mädchens vor, welches mit laborchemischen Hämolysezeichen zur weiteren Abklärung stationär eingewiesen wurde. Das Mädchen war in einem guten Allgemeinzustand und zeigte keine klinischen Ikteruszeichen. Anamnestisch bestanden Husten und eine Blässe seit 3 Monaten. Wir stellten die Diagnose einer Kälteagglutinin-assoziierten hämolytischen Anämie mit passagerer Hepatitis durch Mykoplasmen und behandelten das Kind mit Clarithromycin über zehn Tage.
Paranasal sinus osteoma is the most common benign tumour of the paranasal sinuses. Osteomas are described as giant when they measure more than 3 cm in diameter or weigh over 110 g. Giant osteomas of the maxillary sinus are extremely rare. Aetiology is unknown, but there are three theories about the causes, 'The Developmental theory', 'The Trauma Theory' and 'The Infection Theory'. Osteomas are often noticed incidentally in radiological examinations, unless they are symptomatic. Symptomatic osteomas or/and osteomas occupying more than 50% of the sinus volume are treated surgically. An intraoral approach is often preferred for paranasal sinus osteomas. These tumours have also been associated with Gardner's syndrome. No malignancy transformation has ever been reported and they have an overall excellent prognosis. In this paper, we describe a case of a 37-yearold woman, with a giant osteoma in the left maxillary sinus. The presence of osseous septums attaching the tumour to the walls of the maxillary sinus, creating a star-shaped configuration, has been previously described in only one case.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
