“…Other etiologies are less frequent -other tumors, mostly craniopharyngiomas in 4.2-5.6% and cystic malformations in 2.9-5.2% (46,47,48). It should be noted that these figures come generally from surgical series since definitive diagnosis is only possible after histopathological examination.…”

Pituitary incidentalomas are a by-product of modern imaging technology. the term 'incidentaloma' is neither a distinct diagnosis nor a pathological entity. Rather, it is a collective designation for different entities that are discovered fortuitously, requiring a working diagnosis based on the input of the radiologist, endocrinologist and often a neurosurgeon. In addition to pathological conditions affecting the pituitary gland, a thorough knowledge of the radiological characteristics of normal variants and technical artifacts is required to arrive at an accurate differential diagnosis. after careful radiological and hormonal evaluation, the vast majority of pituitary incidentalomas turn out to be non-functioning pituitary microadenomas and Rathke's cleft cysts (Rccs). Based on the low growth potential of non-functioning pituitary microadenomas and Rccs, periodic MRI surveillance is currently considered the optimal management strategy. stricter follow-up is required for macroadenomas, as increases in size occur more frequently.

“…Meningiomas are isointense in T1-weighted images and hyperintense in T2-weighted images and tumor enhancement is intense and homogeneous with a linear thickening of the dura called the 'dural tail' (Fig. 8) (47). The internal carotid artery is often compressed when the meningioma invades the cavernous sinus (55).…”

“…For diagnosis of meningioma, we found that DTS has a specifi city of 88.5%. Th is specifi city is 5.52% lower than the specifi city noted by Rokni-Yazdi and Sotoudeh (12). DTS has been reported in only a few gliomas.…”

Introduction: The aim of this study is to determine the prevalence of dural tail sign (DTS) in meningiomas, glioblastomas multiforme, metastasis, pituitary macro-adenomas, acoustic neuromas, medulloblastomas, lymphomas and Wegener's granulomatosis, and to reveal if DTS is specifi c for meningiomas. Methods: In this retrospective, cross sectional study 96 patients were included with 95 intracranial and 1 extracranial lesions. The study was conducted in the period from January 2008 to May 2010 and the group pattern was made consecutively. The patients underwent surgery and all 96 lesions were examined by histopathology analysis. DTS was analysed on contrast T1-weighted spin echo images after injection of 0.1 mmol/kg gadolinium contrast medium. The presence of this sign was defi ned using Goldsher et al's criteria. Results: Histopathology results of the 96 lesions revealed the presence of: 35 meningiomas, 25 glioblastomas multiforme, 13 metastasis, 10 pituitary adenomas, 5 acoustic neuromas, 4 medulloblastomas, 3 lymphomas and 1 Wegener's granulomatosis. On the contrast-enhanced T1 MR images, DTS was noted in 31 (32.3%) lesions, in the following histological samples: meningioma, GBM, adenoma, schwannoma, medulloblastoma and Wegener's granulomatosis, while in the cases of metastasis and lymphomas DTS was not noted. We found the dural tail sign to have a sensitivity of 68.6% and specifi city of 88.5% in the diagnosis of meningioma. Conclusion:The dural tail is a common but not a pathognomic sign of meningioma on contrast-enhanced T1 MR images. Other intracranial lesions, such as glioblastoma multiforme, pituitary adenoma, schwannoma, medulloblastoma and Wegener's granulomatosis may also be represented with this sign.

“…The 'dural tail sign', which is useful for the identification of IDEM meningioma, was positive in the current case. However, this finding has also been present in metastatic tumors and lymphoma (14,15). Thus, the differential diagnosis includes all epidural contrast-enhancing lesions, including lymphoma, metastatic tumor, cavernous hemangioma, angiolipoma and HPC.…”

Epidural angiomatous meningioma of the thoracic spine: A case report

Abstract. Spinal epidural angiomatous meningiomas (AMs) are extremely rare lesions. Here, we report on a case of an epidural AM of the thoracic spine with chronic but severe cord compression. The patient underwent a T6-T8 laminectomy through the posterior approach. En bloc resection was achieved, and histopathological examination demonstrated an AM. Delayed paraplegia occurred 4 h postoperatively. The patient was treated with methylprednisolone, hyperbaric oxygen and rehabilitation. Gradually, over the next six months, the bilateral leg strength was improved compared with the preoperative status, and no tumor recurrence was noted. Although epidural AM is extremely rare, it should be included in the differential diagnosis of spinal epidural lesions. A definitive diagnosis is difficult based on magnetic resonance imaging alone due to the nonspecific characteristics of the tumor. Since AM is a histologically benign and highly vascularized tumor, timely gross total resection (GTR) is the most effective treatment. A good clinical outcome may be expected following GTR (Simpson grade I and II resection).
