ACUTE LOBAR NEPHRONIA : REPORT OF TWO CASES

　症例は発熱，腹痛を主訴とする26歳女性と74歳男性の2例．いずれも上腹部CTで楔状の造影不良病変を認め，尿検査で白血球多数，尿培養ではE．coliを検出した．急性限局性細菌性腎炎と診断し，抗生物質の投与を開始した．治療後の上腹部CT像で1例は瘢痕治癒し，他の1例は多少腎の腫大を残したものの，低吸収領域は消失した．急性限局性細菌性腎炎の2例を報告するとともに，若干の文献的考察を行った．

We reported two cases with acute lobar nephronia, a focal form of acute bacterial infection affecting the renal lobule (s) and appearing as a tumor mass. The patients were a 26-year-old woman and a 74-year-old man who had presented with fever and abdominal pain. On CT scanning, poorly marginated area of diminished nephrographic density in the right kidney were revealed. Urinalysis revealed pyuria and urine culture grew E. coli. Through antibiotics administration, subjective symptoms disappeared in both patients in a short time.
