“…In one case report, the specific MRI sequence was not described; we reviewed the remaining 11 reports, including 9 case reports, 1 case series that included 6 patients, and a case contained in a pictorial essay [2][3][4][5][6][7][8][9][10][11][12]. Table 1 summarizes the patient characteristics and clinical findings of these 11 previous reports.…”

“…In addition, less frequently involved sites include the neck, thigh, forearm, popliteal fossa, and lumbosacral region [2]. Only a limited number of published studies describe the magnetic resonance imaging (MRI) features of calcifying aponeurotic fibroma of the upper or lower extremities [2][3][4][5][6][7][8][9][10][11][12][13]. We here report the atypical MRI findings of calcifying aponeurotic fibroma in a 23-year-old female who presented with an intermuscular mass affecting her left upper arm.…”

Calcifying aponeurotic fibroma is a rare soft tissue tumor that occurs in the distal extremities of children and adolescents. We report a case of pathologically proven calcifying aponeurotic fibroma in the left upper arm of a 23-year-old female. Radiographs revealed increased soft tissue density with multiple stippled calcifications in the mid-portion of the patient's left upper arm. Magnetic resonance imaging (MRI) showed a well-defined soft tissue mass with low to intermediate signal intensity on T1-weighted images, heterogeneously low signal intensity on T2-weighted images, and heterogeneous enhancement on fat-suppressed, contrast-enhanced T1-weighted images. Histologically, spindle cell proliferation with scattered calcifications and hyalinization was present. Seven years after surgery, there was no evidence of local recurrence. This is the first report of MRI findings of calcifying aponeurotic fibroma in the upper arm. We also summarize the MRI findings of 16 previously reported cases of calcifying aponeurotic fibroma originating in the upper or lower extremities.

“…Occasionally scalloping of the cortex and thickening of the bone has been reported. 9, 10 Morii et al 11 identified several MRI features seen in a calcifying aponeurotic fibroma. In addition to being distributed subcutaneously, being ill-defined, and having a tendency to infiltrate into or adhere to the surrounding tissue, the masses were of isointensity to low intensity on T1-weighted images.…”

“…CT scans are useful in order to determine the calcified areas of the lesion and its association with the adjacent bone. On MRI, CAF typically appears as an ill-defined subcutaneous mass with intermediate to low signal intensity on T1-weighted sequences and heterogeneous high signal intensity on T2-weighted sequences (6). Prominent areas of globular low signal intensity may be seen on all MR pulse sequences, corresponding with the presence of calcification.…”

“…Prominent areas of globular low signal intensity may be seen on all MR pulse sequences, corresponding with the presence of calcification. CAF usually demonstrates intense heterogeneous enhancement following intravenous gadolinium administration (6). The imaging results from the present case study were consistent with the aforementioned findings.…”

Calcifying aponeurotic fibroma (CAF) is a rare, locally aggressive fibroblastic lesion that occurs predominantly in the distal extremities of children and adolescents. In the present study, a case of pathologically proven CAF arising in the right little finger of a 69-year-old woman is presented. Physical examination revealed a firm, immobile, non-tender mass. Plain radiographs showed a faintly calcified soft tissue mass without bone involvement and computed tomography scans clearly demonstrated the presence of the lesion. Magnetic resonance imaging revealed that the lesion exhibited low to intermediate signal intensity on T1-weighted images and heterogeneous high signal intensity with small foci of low signal intensity on T2-weighted spectral presaturation with inversion recovery images. Contrast-enhanced fat-suppressed T1-weighted images demonstrated intense heterogeneous enhancement throughout the mass. The patient underwent an excisional biopsy. Histologically, the tumor showed a biphasic pattern, composed of a moderately cellular fibromatosis-like component and irregular calcified areas with polygonal epithelioid cells. There has been no evidence of local recurrence four months following surgery. To the best of our knowledge, this case report describes the oldest patient with this condition.
