The purpose of our study was to describe the MR imaging characteristics of fibroma of the tendon sheath. ONLUSION. The diagnosis of fibroma of the tendon sheath can be suggested when MR imaging reveals a focal nodular mass adjacent to a tendon sheath with decreased signal on all pulse sequences and little or no enhancement. F ibroma of the tendon sheath is an infrequently recognized tumor that has historically been difficult to distinguish from other lesions that occur more commonly in the extremities, particularly in the hands and wrists. Initially described as a distinct entity more than 50 years ago by Geschickter and opeland [1], fibroma of the tendon sheath is a lesion composed of tightly packed spindle cells surrounded by collagen fibers. Despite its having a distinct microscopic appearance, it is difficult to suggest the diagnosis of fibroma of the tendon sheath prospectively because the lesion shares imaging features with those of other tumors most notably, giant cell tumor of the tendon sheath. In addition to their common site of origin adjacent to a tendon or tendon sheath, these two lesions are similar in size, location, and gross appearance at pathology. In addition, the lesions occur among similar patient demographics and have similar clinical presentation. Scant documentation of the radiologic appearance of fibroma of the tendon sheath is found in the literature. We retrospectively reviewed our experience with fibroma of the tendon sheath to identify the MR imaging characteristics of this lesion. Materials and Methods Six biopsy-proven cases of fibroma of the tendon sheath, collected over a 9-year period, were retrospectively reviewed. The patients in our study included one man and five women, years old (mean age, 41 years). Radiographs were available for two patients and were reviewed for evidence of a soft-tissue mass, cortical irregularity or erosion, periosteal reaction, and soft-tissue calcification. MR imaging was performed in all patients on high-field-strength (1.0-T or 1.5-T) magnets. The MR imaging sequences performed included spin-echo T1- weighted (TR range/te range, /10 22) in all patients, conventional spin-echo T2-weighted ( /80 90) (n = 3), fast spin-echo T2-weighted ( /68 101) (n = 3), and short tau inversion recovery ( /30 60; inversion time, msec) (n = 4). Gadolinium-enhanced T1-weighted imaging ( /15 23) was performed in all patients, with fat suppression performed in five patients. We analyzed the MR images for signal intensity, signal homogeneity, enhancement pattern, lesion size and location, and proximity of the lesion to a tendon. Enhancement was graded as absent or present. If present, the pattern of enhancement was characterized as homogeneous, heterogeneous, peripheral, or central. Skeletal muscle and fat were used as the reference tissue for all MR imaging sequences. ll images were analyzed by four radiologists working in consensus. This study was conducted with the approval of the institutional review board of the Mayo linic in accordance with the requirements for a retrospective review. Results ll tumors were well defined, round or ovoid, and ranged in size from 0.8 to 2.5 cm. Five patients presented with a soft-tissue mass and one, with vague joint pain. Only JR:180, May

3 MR Imaging of the Tendon Sheath one patient had a history of recent trauma. ll tumors were in the upper extremities and associated with an adjacent tendon. Four tumors were in the fingers and associated with the flexor tendons of the index and little fingers, the extensor tendon of the middle finger, and the flexor pollicis longus. One tumor was in the wrist and associated with the flexor carpi ulnaris tendon, and one tumor was in the shoulder and associated with the biceps tendon. Radiographs in one patient had a normal appearance, and in the other, showed a softtissue mass with mild scalloping of the adjacent bone. No erosion, periosteal reaction, cortical disruption, or soft-tissue calcification was evident. MR imaging showed five (83%) of the six lesions to be mildly to moderately heterogeneous, with heterogeneity more pronounced on T2-weighted images. One of these heterogeneous lesions was homogeneous on T1weighted images. The remaining lesion was homogeneous on both T1- and T2-weighted images. On T1-weighted images, five lesions (83%) showed a signal intensity equal to or less than that of skeletal muscle (Figs. 1 and 2), with the remaining lesion showing a signal intensity slightly greater than that of skeletal muscle. On T2-weighted images, three lesions (50%) showed decreased signal intensity equal to or less than that of skeletal muscle (Figs. 1 and 2). Two of these lesions showed intermediate signal intensity greater than that of muscle and similar to that of fat (Fig. 3), whereas the remaining lesion showed an intermediate signal centrally with decreased signal peripherally. Enhancement patterns varied: two lesions (33%) showed no enhancement, one lesion (17%) had mild peripheral enhancement, and three lesions (50%) showed moderate to marked diffuse enhancement. In two patients, short tau inversion recovery sequences showed decreased signal intensity similar to that of T2-weighted images; in the other two patients imaged with this sequence, lesions showed nonspecific increased signal intensity. D Fig year-old woman with painless mass on flexor surface of index finger., Sagittal fast spin-echo T2-weighted MR image shows oval mass (arrows) similar in signal and deep relative to flexor digitorum profundus., Sagittal T1-weighted gadolinium-enhanced fat-saturated MR image shows no enhancement of mass (arrows). Signal intensity of mass remains equal to that of adjacent tendon., Microscopic specimen from mass shows predominately acellular fibrous tissue with areas of hyalinization and characteristic slit-like vascular channels. D, Lateral radiograph of index finger shows subtle scalloping (arrow) of flexor surface of proximal phalanx. Discussion To our knowledge, the largest series to date on fibroma of the tendon sheath was published by hung and Enzinger [2] in Those authors described the common clinical and demographic presentations of this entity in 138 patients. In their series, 98% of the lesions were in the extremities, JR:180, May % in the upper extremities. The predominant lesion locations in the upper extremities were the fingers, usually the thumb, index, or middle finger (49%); the hand, (21%); and the wrist (12%) [2]. Lesions were typically located on the flexor surfaces, occurring most often in men (75%) years old [2]. Patients often present with a slowly growing mass, occasionally with mild tenderness (31%); fewer than 10% of patients have a history of antecedent trauma [2, 3]. In our series, all lesions were located in an up- 1451

Five of the patients in our study had tumors that showed a signal intensity similar to or less than that of skeletal muscle on T1weighted spin-echo MR images (Fig. 1), as 1452 would be expected in a predominantly fibrous lesion. Two of these patients also showed a signal intensity similar to that of skeletal muscle on both T2-weighted spin-echo and fast spin-echo MR images (Figs. 1 and 2), with no enhancement after administration of contrast material (Figs. 1 and 2). Microscopic examination in one of these patients showed predominantly acellular fibrous tissue with areas of hyalinization (Fig. 2). These imaging and microscopic features are similar to the case reported by Misawa et al. [4]. JR:180, May 2003

5 MR Imaging of the Tendon Sheath Fibroma of the tendon sheath can have different imaging features if areas of increased cellularity or myxoid change are present. In our study, a lesion adjacent to the flexor carpi ulnaris showed a T1-weighted signal intensity equal to that of muscle; with T2-weighted imaging, it showed signal intensity approximately equal to that of fat centrally and somewhat less than that of fat peripherally (Fig. 3). The tumor also showed enhancement that was most marked centrally, and it contained central areas of increased cellularity and myxoid change on a background of vascular slit-like channels within hyalinized stroma. This microscopic appearance reflects the MR imaging findings and accounts for the enhancement pattern, as previously described [5 8]. In our study, mildly increased T1-weighted signal was evident in a tumor adjacent to the biceps tendon an appearance that has not, to our knowledge, been previously reported. This particular lesion also showed signal intensity greater than that of skeletal muscle on T2-weighted images and had peripheral enhancement. These imaging findings correlated microscopically to dense hyalinized fibrocollagenous tissue with widely separated fibroblasts that were small and spindly, and increased capillary vascularity near the lesion surface that was frayed and contained some fibrin deposition. The latter findings likely account for the peripheral enhancement. Fibroma of the tendon sheath is most often confused with giant cell tumor of the tendon sheath at clinical examination and even at gross pathology. oth lesions occur in similar locations, although giant cell tumor is more common (2.7:1) [3]. oth lesions are more common in the upper extremities (86% vs 68% for fibroma of the tendon sheath and giant cell tumor of the tendon sheath, respectively). However, fibroma of the tendon sheath occurs in the lower extremities much less often than does giant cell tumor of the tendon sheath. When compared with giant cell tumor of the tendon sheath, fibroma of the tendon sheath usually occurs in a slightly younger population (35.1 years vs 39.2 years) and has a stronger predilection to occur in men (fibroma of the tendon sheath is times more common in men than in women) [3]. Five of the six patients in our study were women, which does not correspond to the published demographic data, likely reflecting the small number of patients in our study. Microscopically, the two tumors have separate and distinct histologic features. Fibroma of the tendon sheath is hypocellular, with slitlike vascular channels within a dense collagen matrix (Fig. 2), whereas giant cell tumor of the tendon sheath is much more cellular and contains multiple multinucleated giant cells, foamy histiocytes, and hemosiderin [9, 10]. In fibroma of the tendon sheath, findings on standard radiographic imaging are often normal or may show a soft-tissue mass. Erosion or scalloping of the adjacent bone due to pressure erosion from the tumor has been reported but is infrequent [2, 11, 12]. Mild scalloping of the cortex from the tumor was evident in one patient in our series (Fig. 2). Erosion of bone by giant cell tumor of the tendon sheath is recognized in as many as 15% of patients; this finding adds to the difficulty of differentiating between the two entities [13]. To date, only isolated case reports have been published that detail the MR imaging appearance of fibroma of the tendon sheath [4 8, 14]. Many of these reports are in publications other than imaging journals and therefore have limited descriptions and illustrations of the imaging findings. review of these reports reveals a similar spectrum to that of our cases, although more variable signal was noted on T2-weighted images in our study, with areas of high signal intensity correlating to myxoid change histologically. ontrast enhancement in three cases from the literature varied from none, to mild, to marked [4, 7, 8]. When the findings in our six cases are combined with those of the previously reported six cases [4 8, 14], some conclusions about fibroma of the tendon sheath are evident. The imaging features of this lesion overlap with those reported for giant cell tumor of the tendon sheath. The diagnosis of fibroma of the tendon sheath can be suggested when MR imaging reveals a focal nodular mass adjacent to a tendon sheath with decreased signal on all pulse sequences and little or no enhancement an appearance that was seen in two (33%) of our patients. The MR imaging findings vary when areas of increased cellularity or myxoid change occur within the lesion. In these instances, differentiation of fibroma of the tendon sheath from other tumors, such as giant cell tumor of the tendon sheath, is problematic. Limitations of our review include the small size of the study group and the limitations inherent in a retrospective study. dditionally, the absence of unenhanced fat-suppressed images in all patients would make it difficult to exclude minimal amounts of enhancement. In summary, the diagnosis of fibroma of the tendon sheath is favored when the lesion is in a young to middle-aged individual, is located in an upper extremity adjacent to a tendon, is firm to palpation, and is painless, and when MR imaging shows a focal nodular mass with decreased signal on all pulse sequences and little or no enhancement. cknowledgment We thank John S.
