Nuchal fibroma clearly visualized by computed tomography: a case report

Case of nuchal fibroma

“…To the best of our knowledge, there have been only four Japanese cases 6–9 . Even in other Asian countries, we found only one case reported 10 .…”

Nuchal-type fibroma of the buttock: magnetic resonance imaging findings

“…In these reports, the CT fi ndings described the lesion as an ill-defi ned, high-density subcutaneous mass adherent to the dermis and the fascia. 3 The previously described MRI fi ndings Fig. 1.…”

“…[2][3][4][5][6] In most cases, the diameter of the tumor ranges from 2.5 to 8.0 cm, although a giant nuchal-type fi broma with a maximum diameter of 16.5 cm has been reported. 4 Although the pathogenesis of nuchal-type fi broma remains unknown, it has been associated with trauma, diabetes, and Gardner's syndrome.…”

“…[1][2][3] This tumor occurs more frequently in middle-aged adults and is more common in men. 2 In our case, the age of presentation was similar to that in most of the cases described in the literature.…”

“…2 This descriptive term may result in diffi culty in arriving at the correct preoperative diagnosis of this entity because of the extranuchal location of the tumor, especially if the examining physician is unfamiliar with them. There have been several sporadic reports in the English-language medical literature that have included computed tomography (CT) 3 and magnetic resonance imaging (MRI) 4-6 fi ndings of nuchal-type fi broma. Although the clinical, histopathological, and MRI features have been well described in these reports, only a limited description of contrast-enhanced MRI fi ndings has been reported.…”
