ABSTRACT
Purpose: To investigate whether or not intracytoplasmic sperm injection (ICSI) using spermatozoa extracted from testis (TESE-ICSI) is a more effective treatment than ICSI with ejaculated spermatozoa (EJ-ICSI) for primary ciliary dyskinesia (PCD). Methods: We reported a case of PCD in which we performed TESE-ICSI after repeated failure of EJ-ICSI. Together with data from previous case reports, we compared the fertilization rate and pregnancy outcome of TESE-ICSI and EJ-ICSI. Results: In our case, TESE-ICSI improved the morphology of spermatozoa and fertilization rate. However, the outcome was only a biochemical pregnancy. According to the analysis combined with previous reports, there was no difference in the fertilization rate and pregnancy outcome parameters between TESE-ICSI and EJ-ICSI. Conclusions: TESE-ICSI for PCD may improve the fertilization rate compared to EJ-ICSI. However, it does not necessarily improve the pregnancy outcome for a patient with primary ciliary dyskinesia.
ABSTRACT
PURPOSE: To compare unenhanced 3D water-excitation sensitivity-encoding time-of-flight (WEST) and gadolinium-enhanced 3D sensitivity-encoding water-excitation multishot echo-planar (SWEEP) MR angiography (MRA) with regard to conspicuity of uterine arteries in correlation with digital subtraction angiography (DSA). MATERIALS AND METHODS: Eleven consecutive patients with symptomatic uterine fibroids underwent 2 types of MRA before uterine arterial embolization (UAE). From these MRA an interventional radiologist predicted the optimal degrees for oblique DSA projections to reveal uterine arterial origins. Qualitatively, three independent observers reviewed two types of MRA assessing the conspicuity of uterine arterial origins and descending portions using a 3-point scale. Quantitatively, the visualized uterine arteries were measured from their orifice to the end of their descending portions. RESULTS: At UAE, knowing the optimal degrees from MRA, the uterine arterial origins were clearly visualized on all first oblique DSA projections. Mean conspicuity levels of the uterine arterial origins and descending portions were significantly higher and mean length of the visualized uterine arteries was significantly longer for unenhanced WEST MRA than for gadolinium-enhanced SWEEP MRA. CONCLUSION: Unenhanced 3D-WEST MRA was superior to gadolinium-enhanced 3D-SWEEP MRA in demonstrating uterine arteries. The optimal degrees for DSA projections to reveal uterine arterial origins could be accurately predicted using this noninvasive technique.

Malignant transformation is an unusual complication of mature cystic teratomas. Squamous cell carcinomas and adenocarcinomas are predominant among these malignant tumors. We present a 70-year-old Japanese woman with a giant ovarian tumor (30 x 23 x 9 cm) and multiple peritoneal dissemination. The huge tumor was filled with necrotic and fatty tissue and coagula accompanied with hair balls histologically diagnosed as undifferentiated carcinoma with multinucleated giant cells arising in an ovarian mature cystic teratoma. The residual disseminated tumors grew very rapidly and occupied the whole abdominal cavity again 3 weeks after the surgery. The patient died 5 weeks after the operation.
