Meningioangiomatosis is a rare benign hamartomatous lesion. We describe a case of meningioangiomatosis in an 18-year-old boy with a 15 year history of seizures. Computed tomography reveals an irregular calcification density along the right temporal gyrus. Microscopically, irregularly branched blood vessels, surrounded by a concentric arrangement of proliferating spindle cells, are extending into the gray matter from the meningeal surface. Ultrastructural and immunohistochemical examination failed to demonstrate features of meningothelial cell origin in this case. This is the first case of meningioangiomatosis published in Korea along with immunohistochemical and electron microscopic studies. The pathogenesis and previous reports of this lesion will be discussed.

Glioma is the most malignant tumor in the brain, the origin of glioma is still unknown. Recently some papers indicated that glioma may be developed from cerebral cavernous malformation (CCM). We describe a man with a right temporal lobe CCM, after gamma-knife radiotherapy, the patient developed a low-grade astrocytoma in the area of the preexistent CCM. This case, together with other reports, may indicated an oncogenetic properties of CCM, and we proposed that CCM may be a pre-glioma lesion.

We report a case of hepatic cavernous hemangioma with computed tomographic findings of well demarcated nodular lesser attenuation foci within the main low attenuation mass on precontrast scans and non-enhancement of the foci even on the delayed contrast scans. These have been described as one of the atypical findings of cavernous hemangioma earlier in the literature. Surgery proved that sclerosis accounted for the hypodense nodular densities within the hepatic cavernous hemangioma.

Intracranial cavernous angiomas are benign vascular malformations and can be divided into intra-axial and extra-axial lesions. Extra-axial cavernous angiomas are relatively rare and usually arise in relation to the dura mater and mimick meningiomas. We report a case of cavernous angioma that occured in the falx cerebri of a 22-yr-old female patient with the special focus on neuroradiologic findings. This is the fourth case of cavernous angioma in the falx cerebri reported in the literature to our knowledge.

Diffuse hepatic hemangiomatosis without extrahepatic lesions is extremely rare in adults. A case of diffuse hepatic hemangiomatosis involving right lobe in a 50-year-old woman was presented. The hemangiomatosis was demonstrated by ultrasonography, computerized tomography (CT) and magnetic resonance image (MRI), and was confirmed histopathologically. Although diffuse hepatic hemangiomatosis is a rare disease in adults, its diagnosis should be considered in patients with diffuse tumor growth in one or both hepatic lobes and distinguished from malignant tumors. The present case is the first documented case of diffuse hepatic hemangiomatosis in an adult in Korea.

Sclerosing pneumocytoma (SP) of the lung is a rare benign neoplasm. Here, we describe an unusual presentation of SP with a wax-and-wane pattern of growth in a 47-year-old woman. Tumor diameter decreased over a 3-year follow-up period and then increased on serial follow-up computed tomography scans. The mass showed high signal intensity on both T1- and T2-weighted chest magnetic resonance imaging (MRI) and early enhancement with a plateau on dynamic MRI. We speculate that intratumoral bleeding and resorption processes accounted for the changes in tumor size.

PURPOSE: We performed this study to evaluate the incidence of thoracic inlet pathologies. We also evaluated the extension of the thoracic inlet lesions to neck and/or mediastinum to determine anatomic connections between neck and mediastinum. MATERIALS AND METHODS: we evaluated chest radiographs and CT scans of the 41 patients with various pathologies involving this region. RESULTS: Thyroid lesions and malignant lymphomas were the most common pathologic lesions in this region (54%). Thoracic inlet lesions extending from mediastinum included various pathologies including thymic lesion (n=8) in the anterior mediastinum, neurogenic tumor(n=2) in the posterior mediastinum and malignant lymphoma(n=5) in the multiple compartment. Thoracic inlet lesions extending from the neck(n=9) were mostly thyroid lesions(n=8) arising in the visceral space of the neck. Thoracic inlet lesions(n=11) involving both neck and mediastinum were thyroid lesions, abscesses, thymic lesion, malignant lymphomas and cavernous hemangiomas. Thyroid lesions and cavernous hemangiomas showed remarkable enhancement on post contrast enhanced CT. Teratoma contained fat density and Two cases of abscesses contained air density. CONCLUSION: Thyroid lesions and malignant lymphomas were the most common pathologies in the thoracic inlet. There was anatomic connection between neck and mediastinum through the thoracic inlet. CT was valuale in evaluation of the location, extension, and density of the mass for the differential diaguonis of the thoracic inlet lesions.
