OBJECTIVE The aim of this study was to evaluate the usefulness of F-18 fluorodeoxyglucose (FDG) dual-time-point (DTP) positron emission tomography (PET)/computed tomography (CT) with semiquantitative analyses for the initial staging in patients with malignant lymphoma. METHODS Forty-three patients had DTP PET/CT, with 60-min and 2-h scan [n = 8, Hodgkin's(More)
An improved technique of tubeless cutaneous ureterostomy through a single stoma was devised by modifing the traditional cutaneous ureterostomy. Using this method, urinary diversions were performed on 12 cases with malignancies: 6 had radical cystectomy and the other 6 had pelvic exenteration. Normal bilateral ureters were observed in 11 cases in(More)
Palomo's operative method was employed in the surgical treatment of 58 cases with infertile varicocele, and the operative method and therapeutic results were assessed. With the lapse of time after operation, statistically significant improvement was achieved in the sperm density and sperm motility. The post-operative impregnation rate was 55.2%. When the(More)
A case of benign mesothelioma of the tunica vaginalis testis is described. A 56-year-old man with no history of asbestos exposure presented with a swelling of the left scrotal content. A physical examination revealed a hydrocele and an induration on the left epididymal head. A cytological examination of the hydrocele fluid demonstrated clusters of(More)
Two cases of urethral leiomyoma are reported. Two Japanese women 39 and 28 years old presented with the complaint of a painless mass protruding from the anterior wall of urethra to urethral meatus. The mass was firm with associated condyloma acuminatum on its surface and was easily removed by surgical excision. Sixty-four cases of urethral leiomyoma have(More)
Bronchogenic cysts originate from anomalous development of the ventral foregut. Although treatment of asymptomatic bronchogenic cysts remains controversial, symptomatic bronchogenic cysts should be surgically removed. We report a case of a 62-year-old man with an infected bronchogenic cyst. We drained the cyst using transesophageal endoscopic(More)
Objective Myeloblasts are rarely found in the composition of a chronic subdural hematoma (CSH), and reported cases with myeloblasts in CSH have all been associated with systemic hematologic disorders. We present a young man with CSH manifesting the diffuse presence of myeloblasts, although no systemic hematologic disorders were identified. Participant A(More)
Two cases of primary ureteral tumor in the residual ureter are reported. One was in a 40-year-old woman who had undergone simple nephrectomy for renal tuberculosis 6 years earlier. The other was in a 59-year-old man 11 years after ureterostomy for hydronephrosis. They presented with hematuria. Cystoscopic examination revealed a ureteral tumor out of the(More)
