Bilateral lesions damaging the primary auditory cortex or the auditory radiation may cause auditory agnosia. We describe a 67-year-old woman with auditory agnosia after bilateral thalamic hemorrhage. Initially, she showed subcortical deafness for words and environmental sounds. Pure tone audiometry showed a moderate-to-severe hearing loss (mean hearing level, right 56 dB ; left 57 dB), while the recording of auditory brainstem response was normal. Brain CT demonstrated a hematoma in the left thalamus and a narrow low density area suggesting a sequel of the right thalamic hemorrhage. Hearing training was begun using sound sources that were easily recognizable for the patient. Her recognition was better for words than for individual Japanese vowel or consonant-vowel sounds, and the use of lip reading contributed to her better recognition of words. After 2 months, she was able to communicate with medical staff and family members in daily conversation.

Enterovesical fistula is a relatively uncommon complication of colorectal and pelvic malignancies, diverticulitis, inflammatory bowel disease, radiotherapy, and trauma in Asian countries. A case of vesico-ileosigmoidal fistula and a literature review of this disease in Japan are presented. A 70-yr-old male was referred with complaints of urinary pain and pneumaturia. On admission, urinary tract infection and pneumaturia were presented. A barium enema demonstrated multiple diverticulum in his sigmoid colon and the passage of contrast medium into the bladder and ileum. Under the diagnosis of vesico-ileosigmoidal fistula due to suspected diverticulitis of the sigmoid colon, sigmoidectomy and partial resection of the ileum with partial cystectomy were performed. The histopathology revealed diverticulosis of the sigmoid colon with diverticulitis and development of a vesico-ileosigmoidal fistula. No malignant findings were observed. Until the year 2000, a total of 173 cases of vesico-sigmoidal fistula caused by diverticulitis had been reported in Japan. Pneumaturia and fecaluria are the most common types, presenting symptoms in 63% of the cases. Computed tomography, with a sensitivity of 40% to 100%, is the most commonly used diagnostic study. For patients with vesico-sigmoidal fistula, resection of the diseased sigmoid colon and partial cystectomy with primary anastomosis are the safest and most acceptable procedures, leading to the best results.
