“…Gasco et al [ 10 ] reported a large ALM originated from the transverse sinus. A few cases reported small nodules on the dura [ 6 , 11 , 13 ], and a peculiar case in auditory meatus [ 9 ]. Some ALMs occur on cranial bone, with the majority were in the facial bones such as the mandible and maxilla [ 14 ].…”

Angioleiomyoma, a rare intracranial tumor: 3 case report and a literature review

2014

View full text Add to dashboard Cite

Three cases of intracranial angioleiomyoma (ALM) in our neurosurgery center are reported in detail. ALM is a benign soft tissue tumor comprised of mature smooth muscle cells and a prominent vascular component, which is extremely rare as a primary intracranial lesion. Altogether, only 12 cases were recorded in the literature to date, to the best of our knowledge. Case 1 is the second report of intra-sella ALM, a 51-year-old woman presented with visual deterioration for 2 months. An MRI showed an intra-sella 3-cm tumor, partially flame-like, enhanced with gadolinium. Using microscopic endonasal transsphenoidal approach, the tumor was completely resected with great difficulty. At 11 days post-surgery, she died of a sudden catastrophic nasal hemorrhage. An angiography revealed a pseudo-aneurysm of ICA (internal carotid artery). Case 2 is a 49-year-old man who presented with weakness of the lower limbs for 1 year. A large subtentorial mass was found affixed to the torcular and straight sinus, which was partially flame-like, dramatically enhanced as in case 1. Case 3 is that of a 77-year-old man. An ALM mass was revealed in the diploe of left temporal bone, and had eroded the inner table. Immunohistochemical workup confirmed the diagnosis of angioleiomyoma in all 3 cases. The radiology, operation, and complication of surgery in each case were discussed. In conclusion, intracranial ALMs are extremely rare, usually located ex-neuro axis (such as in our cases), in the sella, in posterior fossa, or in the skull. Magnetic resonance imaging (MRI) revealed a special feature of flame-like partial enhancement that may be helpful to distinguish ALM from pituitary tumors or meningiomas, and should result in the consideration of this rare tumor entity early on in the diagnostic process. A definitive diagnosis depends on histological analyses. The resection of ALM in certain locations is difficult and risky because of the rich blood supply.

“…In 1994 Lach et al 10 described the first primary intracra nial angioleiomyoma, in an extraaxial location (leptom eningeal). To the present time, 4 additional intracranial cases have been documented; 4,7,8,14 of these, only the case reported by Ravikumar et al 14 was intraaxial (basal gan glia). Karagama et al 7 and Kohan et al 8 have verified le sions in the IAM.…”

Angioleiomyomas are benign neoplasms most often located in the subcutaneous tissue of middle-aged individuals and usually confined to the subcuticular and deep dermal layers of the lower extremities. An intracranial site for this tumor is exceedingly rare, with very few reports documenting locations in the neuraxis. To the authors' knowledge the present case represents the first reported instance of an infratentorial angioleiomyoma. The authors conducted a review of selected English-language papers published since 1960 describing well-documented cases of intracranial vascular leiomyomas, with detailed information on the clinical presentation, radiology, pathology, and particulars of surgical management in each case.

“…►Tables 1, 2, and 3 summarize the clinical, radiologic, surgical, and pathologic findings in all previous reports about intracranial ALMs including our case. [1][2][3][5][6][7][8][9][10][11][12][13] The data reviewed here show that intracranial ALMs were more frequently found in men (9 cases: men, 3 cases: women; 1 case: unknown) than in women in contrast to extremity ALMs ( Table 1). The average age was 43.5 years (standard deviation [SD]:16).…”

Cavernous Sinus Angioleiomyoma: Case Report and Review of the Literature

et al. 2014

View full text Add to dashboard Cite

Cavernous sinus angioleiomyoma (ALM) is extremely rare. Only three cases have been reported to be cavernous sinus ALM, and very few reports described characteristic findings for intracranial ALMs in detail. We report a new case of cavernous sinus ALM, with detailed information on the clinical presentation, radiology, pathology, and surgical approach. A 52-year-old woman had a 6-month history of right eye discomfort. Magnetic resonance imaging showed a right cavernous sinus tumor with heterogenous blush enhancement. Enhanced computed tomography scans and angiography showed small nodular enhancement in the tumor. Complete tumor resection was achieved via an extradural temporopolar approach. ALM was identified based on histologic examination. Intracranial ALMs are different from the ALMs that occur in the extremities based on our review of the literature. Intracranial ALMs appear more frequently in men than women. The cavernous type was the most common pathologically, and they occur often in the epiperidural location. Because cavernous sinus ALM occurs in the interdural space, an epidural approach should be selected. Therefore, it is important to include cavernous sinus ALM into a differential diagnosis of a cavernous sinus tumor. The blush enhancement and nodular enhancement within this lesion may be useful to distinguish cavernous sinus ALM from other differential diagnoses.
