A 34-year-old female patient underwent uterine artery embolization (UAE) to control massive postpartum hemorrhage. The interventional radiologist was not informed of the patient's significant history of uterine myoma. Although no significant signs of complications or “red flags” were observed during the procedure, follow-up computed tomography performed four weeks later revealed evidence of a large, globe-like fluid collection with air bubbles in the uterus. The finding and pathology was initially diagnosed as uterine necrosis, which led not to interventional percutaneous drainage; instead, dilation and curettage with resectoscope was performed. The surgical and pathological diagnosis was “expulsion of pyomyoma in the uterine cavity.” Awareness and precise knowledge of imaging findings of pyomyoma and uterine necrosis are important for early diagnosis and treatment of UAE-related complications.

OBJECTIVE: There are few reports on the clinical outcomes of the percutaneous endoscopic lumbar discectomy(PELD) with laser for the treatment of far lateral lumbar disc herniation. The objective of this study is to assess the safety and efficacy of the PELD with laser for the treatment of far lateral lumbar disc herniation. METHODS: The clinical records of 42 patients who had far lateral lumbar disc herniation and underwent PELD with laser between January 1996 and August 2002 were analyzed retrospectively. There were 24(57.1%) males and 18(42.9%) females, with a mean age of 53(range, 26-73) years. The surgical procedure was performed via a posterolateral approach after induction of a local anesthesis. The clinical outcomes were measured with MacNabO s criteria. The mean follow-up period was 38(range, 5-77) months. RESULTS: Clinical outcomes were revealed as follows: excellent in 28 patients(66.7%); good in 11(26.2%); fair in 2(4.7%); and poor in 1(2.4%). Therefore, the percentage of successful(excellent and good) outcomes was 92.9%. There was no statistically significant variation in the success rates according to age and operation level(p>0.05). Before the introduction of the high resolution endoscope, the success rate was 90.3% but after upgrading to the high resolution endoscope, the success rate was 100%, and there was a statistically significant variation in the success rate(p<0.05). In all cases, there was no complication or recurrence. CONCLUSION: As a minimally invasive surgery, PELD with laser is a safe and efficacious procedure for the treatment of far lateral disc herniation.

Atypical teratoid/rhabdoid tumor (AT/RT) of spine usually reported to develop in the brain, while it rarely manifest in the spine. It consists of rhabdoid cells and is highly malignant. AT/RT appears at various sites throughout the body, such as in the central nervous system, liver, kidneys, abdomen, and soft tissues. Among them, spinal AT/RT is rare, and AT/RT of lumbar spine is extremely rare; only a few cases have been reported. We present the case of an AT/RT of lumbar spine in a 16-month-old boy.

Usher syndrome type II (USH2) is the most common form of Usher syndrome, characterized by moderate to severe hearing impairment and progressive visual loss due to retinitis pigmentosa. It has been shown that mutations in the USH2A gene are responsible for USH2. The authors herein describe a 34-year-old Korean woman with the typical clinical manifestation of USH2; she had bilateral hearing disturbance and progressive visual deterioration, without vestibular dysfunction. Molecular genetic study of the USH2A gene revealed a novel frameshift mutation (c.2310delA; Glu771LysfsX17). She was heterozygous for this mutation, and no other mutation was found in USH2A, suggesting the possibility of an intronic or large genomic rearrangement mutation. To the best of our knowledge, this is the first report of a genetically confirmed case of USH2 in Korea. More investigations are needed to delineate genotype-phenotype correlations and ethnicity-specific genetic background of Usher syndrome.
