PURPOSE: To evaluate characteristic CT features of twisted ovarian tumors and to assess the diagnostic value of the existence of twisted vascular pedicle in torsion of ovarian tumors. MATERIALS AND METHODS: Weretrospectively reviewed the clinical and CT findings in eleven patients with ovarian tumor torsion confirmed bysurgery. Pre- and post-contrast CT were available in nine patients and post-contrast CT in two. All twisted ovaries, tubes, and tumors showed hemorrhagic infarction and necrosis. RESULTS: All patients had twisted vascular pedicle of the ovarian tumor evaluated by CT. Eight patients with left ovarian tumor had twisted vascular pedicleon the left side of the tumor, and three patients with right ovarian tumor on the right side of the tumor. Themorphologic characteristics of twisted vascular pedicle were coiled target appearance (4 cases), beak appearance(3 cases), doughnut appearance (3 cases), and mass with irregular margin (1 case). High density on precontrast CT scan was present in the pedicle in four cases and linear contrast enhancement was seen in the peripheral portionof the pedicle in four cases. The shape, density and location of ovarian tumors were inconsistent, however, contrast enhancement was not seen in all patients. Other findings were uterine deviation, loss of fat plane andpelvic fluid. CONCLUSION: Detection of twisted vascular pedicle by CT may be useful for the diagnosis of ovariantumor torsion.

Seckel syndrome is a rare autosomal recessive disease. The characteristic features of Seckel syndrome include Intrauterine and postnatal growth deficiency, severe microcephaly, and a bird-like head. General appearance of our patient was characterized by Pre- and postnatal growth retardation, microcephaly, large eye, and a beaked nose. The patient had mental retardation with CNS anomalies. The CNS anomalies seen in the patient included cerebral dysgenesis and cerebellar atrophy. So, we report the case of CNS anomalies in Seckel syndrome.

OBJECTIVES: We analyzed the pneumatization pattern of the frontal recess (FR) in a Korean population. We also determined the correlation between the volume of the agger nasi cell (ANC) and the anterior-to-posterior (A-P) length of the frontal isthmus (FI) and FR. METHODS: Multiplanar paranasal sinus computed tomography (CT) images from 105 patients who underwent endoscopic sinus surgery were reviewed. The prevalence of frontal recess cells (FRCs), thickness of the frontal beak (FB), volume of the ANC, A-P length of the FI, and FR were evaluated. RESULTS: The ANC was identified in 96% of the patients and frontal cells (FCs) in 32% (FC type 1, 24.2%; type 2, 4.2%; type 3, 3.1%; and type 4, 0%). The prevalences of frontal bullar, suprabullar, supraorbital ethmoidal, and interfrontal sinus septal cells were 10%, 7.8%, 3.6%, and 6.8%, respectively. The A-P lengths of the FR and FI were 10.1+/-3.1 and 8.4+/-2.9 mm, respectively. The thickness of the FB was 7.8+/-1.8 mm and the volume of the ANC averaged 394.1+/-240.5 mm3. The thickness of the FB did not correlate with the volume of the ANC. In contrast, the A-P length of the FI and FR were positively correlated with the volume of the ANC. CONCLUSION: ANCs and FCs were found in 96% and 32% of the cases in this series. FC type 4 was not seen. What appeared to be FC4 on conventional CT was identified as FBC from reconstructed parasagittal images. A large ANC increased the A-P length of the FI and FR, regardless of the thickness of the FB.

Primary hepatic leiomyosarcoma is a rare tumor, most frequently occurring in liver parenchyma. We recentlyencountered an exophytic hepatic leiomyosarcoma ; CT scans indicated an indistinct border, with the parenchyme ofthe liver and parenchymal beaking suggesting a primary hepatic mass. We present an unusual case of primaryleiomyosarcoma which showed exophytic growth.

PURPOSE: To evaluate the clinical and urodynamic significance of the beaking sign at cystography in patients with stress urinary incontinence (SUI). MATERIALS AND METHODS: We retrospectively reviewed the cystograms of 253 patients with SUI, defining the beaking sign as the triangular contrast collection below the bladder base in the resting state without overt leakage. Various clinical parameters including patient age, symptom duration, parity, the one-hour pad test, and urodynamic study data including Valsalva leak point pressure (VLPP) and maximal urethral closing pressure (MUCP) were compared between the beaking-positive and the beaking-negative group. The distribution of Blaivas type in SUI between these two groups was also analysed. RESULTS: The beaking sign was observed in 153 patients (60%). Those who were older and showed greater parity more often belonged to the beaking-positive group than the beaking-negative (p<0.05). Both VLPP and MUCP were significantly lower in the beaking-positive group than in beaking-negative group (p=0.03; p=0.01, respectively). Type-0 or -I SUI was more common in the beaking-negative group, while the frequency of other types was similar between the two groups. CONCLUSION: The beaking sign has clinical and urodynamic significance, reflecting functional deficiencies of the intrinsic sphincter, and may possibly be regarded as an additional parameter in the planning of treatment.

PURPOSE: The aim of this study is to evaluate the normal anatomy of the anterior diaphragm below the level of the xiphoid process by analyzing CT scans. MATERIALS AND METHODS: CT scans of 100 patients with no peridiaphragmatic lesions were retrospectively analyzed. All CT scans were performed with coverage of the whole diaphragm in the inspiration state. We evaluated the type of the anterior diaphragm, according to Gale's classification, the discontinuity of the anterior diaphragm (defect), the presence of a focal protrusion of the diaphragm (beak), and the thin line continuous with the diaphragm (line), and the relationship between the internal thoracic artery and the anterior diaphragm. Ed. Note: confirm wording. RESULTS: The frequency of defect, beak, and line were 17%, 27%, and 9%, respectively. Beak mainly (18/27) arose from the fusion between the anterior diaphragm and the transversus abdominis. The internal thoracic artery seen on CT was always located in the anterior portion of the transversus abdominis or transversus thoracis. CONCLUSION: The discontinuity of the anterior diaphragm and the focal protrusion of the diaphragm that mimics a hernia are relatively common variations of the anterior diaphragm. The internal thoracic artery may not be the cause of Morgagni foramen.

PURPOSE: This study aimed to analyze the clinical characteristics, results of operational method and causes of operational failure in rhegmatogenous retinal detachment except macula hole induced retinal detachment, and to analyze several factors of vision. METHOD: We reviewed the records of 720 patients, 743 eyes with regmatogenous retinal detachment who had undergone operation from January 1990 to December 1999, and followed up for at least 3 months or longer. RESULT: Scleral buckling (728 eyes, 98.0%), gas injection (9 eyes, 1.2%) and vitrctomy (6 eyes, 0.8%) were done as a primary operation. Anatomical success rate was 684 eyes(34.9%). A good visual acuity ( V A >or=0.5) was achieved in 239 eyes (34.9%), reasonable vision (VA 0.4~0.15) in 192 eyes(28.1%), ambulatory vision (VA 0.1~0.02) in 95 eyes (13.8%), whereas 158 eyes (23.2%) became blind (VA beak and more reoperation cases. CONCLUSION: During the past 10 years, we found that functional outcome was not favorable in spite of the high anatomical success. This prognostic factors make us predict postoperative visual outcome of rhegmatogenous retinal detachment.

OBJECTIVES: Draf IIb approach provides wide, unilateral access to the frontal sinus. This approach can be extended without destruction of the contralateral frontal sinus drainage pathway, performed during Draf III (modified Lothrop) procedure. There is limited data in the literature regarding the use of modified Draf IIb procedures. METHODS: Patients treated with extended Draf IIb procedures in a single center were retrospectively assessed. RESULTS: Ten patients were identified, including 2 cases of osteoma, 1 inverted papilloma, 1 carcinoma, 5 mucoceles, and 1 chronic rhinosinusitis patient. Six patients had undergone prior surgery, including external procedures in 3 cases. Modifications of Draf IIb were classified as the following: removal of the anterosuperior nasal septum adjacent to the nasal beak, removal of the intersinus septum, and a combination of the above-mentioned methods (upper nasal septum and intersinus septum removal). There were 3 patients operated on with type 1 modification, one patient with type 2 modification, and 6 patients with type 3 modification. There were no perioperative complications. CONCLUSION: In selected cases, extended Draf IIb procedures are safe and effective in the treatment of frontal sinus disease.
