Heterotopic mesenteric ossification is a very uncommon disorder that is characterized by new bone formation in the mesentery, which does not normally undergo ossification. A 52-year-old female experienced a small bowel obstruction 12 days after a segmental resection of the small bowel following a trauma. A laparotomy was performed 16 days after the initial operation, and a 2 cm hard mass was detected in the small bowel mesentery, with severe fibrous adhesions around the mass, involving the jejunum, which required resection. Postoperatively, the patient developed an intraabdominal abscess, followed by intestinal fistulation. The patient gradually recovered by conservative management, and left hospital 70 days after the first operation. Microscopic examination of the mass showed well oriented trabeculae of the osseous tissue, osteoid formation, with fine calcification and osteoblastic activity, but there was no formation of mature lamellar bone or clear evidence of the "zone phenomenon" that is classically described in heterotopic ossification. These findings appeared consistent with an early stage of heterotopic ossification. The etiology and pathogenesis are unknown; the heterotopic mesenteric ossification was thought to be associated with the trauma (intraabdominal surgery). The previous literature on heterotopic mesenteric ossification is reviewed, and a new case reported.

OBJECTIVE: Detection of intracranial multiple aneurysms, including mirror-image aneurysms, have recently been increasing with the development of diagnostic techniques. However, studies of mirror-image aneurysms have been rare in South Korea. Thus, we intend to report our hospital's experience with mirror-image aneurysms during the past 20 years along with a review of relevant literature. METHODS: We analyzed medical records and image data from patients with cerebral aneurysms who had been admitted to our institution from January 1988 to June 2007. We divided the patients into three groups and investigated the clinical patterns of mirror-image aneurysms (Group 1). We then compared them with patients exhibiting non-mirror multiple aneurysms (Group 2) and the patients with solitary aneurysms (Group 3). We also statistically analyzed the age, sex, smoking habits, medical histories, and prognoses of the patients. RESULTS: Mirror-image aneurysms were found in 62 (5.1%) of the 1,209 patients admitted for cerebral aneurysms over the past 20 years. Of the mirror-image aneurysms, 48% were located in the posterior communicating artery (PcoA), and 40% were in the middle cerebral artery (MCA). Ruptures of aneurysms occurred slightly more frequently on the right side and when the aneurysm was larger and its shape was more irregular. Women, particularly menopausal women aged 50 and older, were shown to be at higher risk. Smoking was also a risk factor. However, there were no significant differences in prognoses among the three groups. CONCLUSION: We should pay attention to the possibility of mirror-image or multiple aneurysms when diagnosing and treating menopausal women and smokers, particularly if the cerebral aneurysm is located in the MCA or PcoA.

PURPOSE: To determine the means, medians and reference intervals for TSH (thyroid-stimulating hormone) and fT4 (free thyroxine) for each month of gestation and for three trimesters in Korean pregnant women. METHODS: Serum samples were collected from 265 pregnant women with singleton gestation. Levels of TSH, fT4 were measured by immunoassay. After exclusion of subjects with positive antimicrosomal autoantibodies, the means, medians and reference intervals based on 2.5th and 97.5th percentiles for TSH, fT4 were determined. RESULTS: The study population consisted of 94 women in first trimester, 49 women in second trimester, and 122 women in third trimester. The trimester-specific reference intervals were: TSH (1st trimester: 0.03~2.72, 2nd: 0.27~2.29, and 3rd: 0.03~2.88 mIU/L), fT4 (1st trimester 4.50~19.75, 2nd: 4.70~12.98 and 3rd: 5.07~11.84 pg/mL). fT4 levels were significantly lower in the second and third trimesters. TSH levels were lower in the first trimester than second and third trimester, with gradual elevation in the second and third trimester. CONCLUSION: Levels of TSH, fT4 during pregnancy differ from those in non-pregnant women. Gestational age specific reference intervals will play a cental role in screening and diagnosis of thyroid disorders. Further studies for normal reference ranges during pregnancy are needed to create reference intervals in Korean pregnant women.
