Abstract Rhinolith is the presence of nasal mass which is composed of calcium carbonate, magnesium carbonate, calcium phosphate and magnesium phosphate. Rhinoliths develop around organic or inorganic nidus having irregular or spongy surface that has stayed in the nasal cavity for a long time. Nidus arises in most of the cases from an exogenous origin such as fruit seeds, grains of vegetables and legumes, pieces of paper, button, bead, pieces of toy and finally pieces of stone and sand. They rarely arise from an endogenous nidus. Endogenous nidus generally consists of mislocated tooth, pieces of bone, blood cloth, dried purulent secretion or desquamated epithelium. The dimensions of rhinoliths can be small or can fill the nasal cavity. Rinolith cases are rare and patients frequently complain of longstanding nasal obstruction, nasal and oral malodor, purulent rhinorrhea and chronic headache. But sometimes patients with rhinolith are coincidentally diagnosed during routine physical examination. Early diagnosis is essential to reduce the morbidity. In this case report we present a 45 year old female rhinolith case. Her computerized tomography and nasal endoscopy findings, differential diagnosis and management are also presented. Our aim in this case report was to remind rhinolith in the differential diagnosis of nasal cavity masses and emphasize the importance of routine otorhinolaryngological examination even if the patient has no complaints. Keywords: Rhinolith Ozet Rinolitler nazal kavite icinde yerlesen kalsiyum karbonat, magnezyum karbonat, kalsiyum fosfat ve magnezyum fosfattan olusan kitlelerdir. Rinolitler, burun boslugunda uzun sure kalan, duzensiz yuzeyli veya delikli, organik veya inorganik bir nidus etrafinda gelisler. Bu nidus, cogu olguda meyve cekirdekleri, sebze-baklagillerin taneleri, kagit parcalari, dugme, boncuk, oyuncak parcalari ve tas-kum parcalari gibi eksojen kaynaklidir. Cok seyrek olarak da endojen kaynakli niduslar izlenebilmektedir. Endojen niduslar genellikle; yanlis yerlesimli dis, kemik parcalari, kan pihtisi, kurumus puy veya deskuame epitelden meydana gelir. Rinolitlerin boyutlari kucuk olabilecegi gibi tum nazal kaviteyi doldurabilir. Rinolit vakalari nadir gorulen lezyonlardir ve siklikla burun tikanikligi, purulan burun akintisi, burun kanamasi sikayetleri ile basvurabilecegi gibi bazen de rutin fizik muayene sirasinda tesadufen tespit edilir. Morbiditeyi azaltmak icin erken tani ve tedavi onemlidir. Bu vaka takdiminde rutin fizik muayenede tesadufen tespit edilen 45 yasinda bayan rinolit vakasi; bilgisayarli tomografi ve nazal endoskopi bulgulari, ayirici tanisi ve tedavisi ile sunulmustur. Calismanin amaci nazal kavitede izlenen kitlelerin ayirici tanisinda rinoliti hatirlatmak ve hastanin sikayetinden bagimsiz rutin kulak burun bogaz fizik muayenenin onemini vurgulamaktir.
