Giant cavernous angioma of the temporal lobe: a case report and review of the literature.

Cavernous angiomas of the central nervous system are angiographically occult vascular lesions and are easily diagnosed by magnetic resonance imaging (MRI). Giant cavernous angiomas (GCA) are rare, with only 11 cases reported in the literature. Imaging appearance of GCAs has not been reviewed previously. We report a GCA of the temporal lobe, and discuss its computed tomography and MRI findings in the view of the literature. Imaging appearance of GCAs is variable. Some GCAs have features that are similar to those of typical cavernous angiomas, whereas some lesions may be purely cystic; and some present with significant contrast enhancement and mass effect, mimicking neoplasms. While the presence of hemosiderin, blood degradation products, and calcification may be helpful in the diagnosis of some cases, the correct diagnosis is not apparent until histopathological evaluation of the specimen is made in many instances.

Islets of meningioma in an acoustic schwannoma in a patient with neurofibromatosis-2: pathology and magnetic resonance imaging findings.

Mixed tumors of the cerebellopontine angle, composed of meningioma and schwannoma components, are extremely rare; so far, only 12 cases have been reported in the literature. They are thought to be exclusively associated with neurofibromatosis-2. We present a mixed tumor of schwannoma and meningioma in a patient with neurofibromatosis-2 and discuss the pathology and magnetic resonance imaging (MRI) findings in relation to the literature. Review of the literature shows that a typical MRI pattern has not been established for mixed tumors and it seems unlikely that a meningioma component can be differentiated within a schwannoma preoperatively.

Lymph node revealing solution: is it effective on detecting minute lymph nodes?

AIMS: The aim of this prospective study is to detect the efficiency of a previously described lymph node revealing solution (LNRS) in comparing with conventional lymph node dissection and re-dissection in colon, breast and urinary bladder carcinomas. METHODS: Total 30 cases in which less than 10 lymph nodes were found by conventional method, were immersed for 6-8 hours in LNRS, dissected and processed. Control group, 12 cases, was first dissected then a second conventional dissection was performed. At the end, specimens were again immersed in LNRS for 6-8 hours and last dissections were done. MAIN RESULTS: In the first group, a total of 150 lymph nodes, 46 of them with metastasis were detected. After using LNRS, 26 additional lymph nodes among which 10 were positive were detected. When compared with the results of conventional dissection, the increase in number of total and metastatic lymph nodes with LNRS was significant (p<0.01). The mean size of the lymph nodes detected by the conventional and LNRS methods was 6.8 and 4.2 mm, respectively. The pathologic lymph node stage was changed in three bladder carcinoma cases, and one breast carcinoma. In the control group, 75 lymph nodes (11 with metastases), 19 lymph nodes (3 with metastases), 14 lymph nodes (one with metastases) were detected after first and second conventional dissection and LNRS methods, respectively. CONCLUSION: LNRS enhanced the number of total and metastatic lymph nodes and is effective in detecting small lymph nodes. This method is useful for accurate staging where the number of detected lymph nodes is too small by the conventional method.
