| Abstract | 「要旨」髄液鼻漏が疑われた12例に対して, 111In-DTPA, 37MBq髄注による脳槽シンチグラフィおよび鼻栓カウント法を18検査施行した. 鼻栓は鼻腔内に6時間留置し, 30分以上伏臥位を取らせた. 髄液鼻漏と診断された症例は全例, 鼻栓カウント1kcpm以上を示した. 持続性, 間歇性, 潜在性/無鼻汁例のそれぞれに対して, 髄液鼻漏100%(5/5), 60%(3/5), 25%(2/8)であった. シンチグラフィにて髄液鼻漏を検出し得たのは持続性鼻汁の2例のみであった. したがって, 髄液鼻漏が疑われる患者に対して, 持続性鼻汁例に対してはMRIまたは CT cisternography を優先すべきであり, 間歇性/潜在性鼻汁例に対しては鼻栓カウント法を最初に施行すべきと思われた. 綿栓を鼻腔内に6時間留置し, 少なくも30分間伏臥位を取らせた鼻栓カウント法は髄液鼻漏検出のための簡便かつ有用な方法と思われる. |

| Abstract | A combination study of cerebrospinal fluid scintigraphy and nasal pledget counts was performed using 37 MBq of 111In-DTPA in 12 patients with suspected rhinorrhea. A pledget was inserted and dwelled in each nasal cavity for 6 hours, with the patient prone during at least 30 minutes. A total of 18 studies was implemented and nasal pledget counting method successfully diagnosed all of CSF rhinorrhea. Diagnosis was possible when pledget counts were greater than 1 kcpm. In patients with persistent, intermittent and occult/no nasal discharge, rhinorrhea was found in 100% (5/5), 60% (3/5), 25% (2/8), respectively. Two cases only exhibited positive scintigraphy. MRI or CT cisternography should be first performed in patients with persistent discharge, but in patients with intermittent/occult discharge pledget counting method might take priority of other diagnostic modalities. In conclusion, nasal pledget counting method is a simple and useful tool for detecting rhinorrhea. |
