Intralobar Pulmonary Sequestration, Supplied from Left Gastric Artery: A Case Report

Pulmonary sequestration is a relatively rare anomaly. Arterial supply is usually derived from the aorta or its major branches, or very rarely from the left gastric artery. We present a case of intralobar sequestration in which blood was supplied by the left gastric artery.

Desmoplastic Small Round Cell Tumor: Radiologic Findings

PURPOSE: To evaluate the radiologic findings of intra-abdominal DSRCT. MATERIALS AND METHODS: We reviewed sixcases of pathologically proven DSRCT of the abdomen. Five of these patients were men and one was a woman ; theiraverage age was 26.8 years. We retrospectively analyzed CT(n=6) and MRI(n=4). RESULTS: In all patients, largerelatively well defined lobulated mass was seen;this arose from the peritoneal surface, and its average size was12.6(range, 10-18)cm. After the administration of contrast material, the masses showed inhomogeneous enhancement,and in addition, the following features were seen: irregular internal septations (n=5); necrosis (n=3); andamorphous calcification (n=4). Various associated findings such as ascites (n=4) and multiple para-aortic lymphnode enlargement (n=4) were present; omental cake (n=5), liver metastasis (n=1), cervical lymphadenopathy (n=1),hydronephrosis (n=1), small bowel obstruction (n=1), scrotal swelling (n=1) and collateral vessels by encasedaorta and renal vein (n=1) were also seen. CONCLUSION: In young male patients with a large heterogeneous enhaneedcalcified abdominopelvic mass and findings of carcinomatosis on both CT and MR images, DSRCT should be inelvded inthe differential diagnosis.

Radiologic Findings of Granulosa Cell Tumor of the Ovary

PURPOSE: To evaluate the radiologic findings of granulosa cell tumor of the ovary. MATERIALS AND METHODS: Fourteen cases (fifteen tumors) of pathologically confirmed ovarian granulosa cell tumor were retrospectively analyzed on the basis of CT (n=10), MR imaging (n=4), and ultrasound (n=7) findings. The patients' mean age was 44.3 (range, 5-71) years. RESULTS: The mean diameter of the tumors was 12.1 (range, 5-26.5)cm. Thirteen cases were unilateral, and one was bilateral. Eleven tumors (ten cases) were mainly solid and eight of these had focal cystic components. Multilocular cysts accounted for three cases, and in two of these, mural nodules were present. One case was a unilocular cyst with no mural nodule. Ten cases were well demarcated. All the solid tumors were enhanced on postcontrast CT and MR imaging. Endometrial thickening was seen in five cases, ascites in six, and peritoneal implants or omental fat infiltration in five. One was associated with lymph node metastasis. All the postmenopausal patients had solid tumors, whereas 66.7% (4 of 6 cases) of young adults and children had cystic tumors. CONCLUSION: Granulosa cell tumors of the ovary were solid or cystic; the former were more common. There were no characteristic findings which permitted definitive differentiation from other ovarian tumors.

Invasive Ductal Carcinoma vs. Invasive Lobular Carcinoma: Mammographic Findings

PURPOSE: The purpose of this study is to evaluate mammographic findings of invasive ductal carcinoma(IDC) and invasive lobular carcinoma(ILC)and to find differential points between the two. MATERIALS AND METHODS: 239 patients, who underwent mammography prior to surgery and were proved to have IDC(224 patients) or ILC(15 patients)pathologically, were analized retrospectively. On mammogram, presence of mass and micro calcification were analized. When there was a mass on mammogram, lesion opacity was classified into high, equal, or low opacity andborder of the mass was classified into spiculated, poorly marginated, and well-marginated. When there was nodefinite mass, mammographic findings were classified into asymmetric opacity and no mass. RESULTS: Masses were observed in 168 patients(75%) of IDC and 12 patients(80%) of ILC. Border of the masses were spiculated(n=50,22.3%), poorly marginated(n=112, 50%), or well-marginated(n=6, 2.7%) in patients with IDC. Spiculated and poorly marginated borders were observed in 8 patients(53.3%) and 4 patients(26.7%) respectively, in patients with ILC. Microcalcifications were seen in 88 patients(39.3%) of IDC and 2 patients(13.3%) of ILC. Equal or low opacities ofthe lesions were observed in 29 patients(17.3%) of IDC and 5 patients(33.3%) of ILC. CONCLUSION: Although equalor low opacities were observed more frequently in ILC and microcalcifications were noted more frequently in IDC,it was difficult to differentiate the two diseases based on mammographic findings.
