Abstract Introduction: Fibrous dysplasia is a benign bone lesion characterized by replacement of normal bone by fibrous connective tissue, and its diagnosis is based on clinical, radiological and histological findings. Objective: The aim of this study was to report a case of unilateral fibrous dysplasia in the maxilla, in the palate region, by using computed tomography. Results: On examination it was observed: a nodular lesion, with similar staining to the palatal mucosa with varicosities, regular edges, irm and painless. The radiographic indings on computed tomography showed one diffuse and heterogeneous thickening of the bony elements involving the hard palate extending to the posterior wall of the maxillary antrum. We opted for the preservation of the case, considering the age of the patient, the absence of facial asymmetry and lack of aesthetic and functional impairment. Conclusion: Thus, we emphasize that the knowledge of morphological changes is important for the diagnosis of bone pathologies, and the dentist must be familiar with the normal morphology of the structures and their possible abnormalities.

Rare Lesion

An intraosseous lipoma is a rare benign bone lesion that proliferates from mature lipocytes. It occurs most frequently in the lower limb, particularly in the calcaneus. The talus is an unusual location for this rare lesion. A review of the literature produced only two reports with talar intraosseous lipomas under the name of intraosseous lipomatosis, which described multiple lipomas in different areas. We describe a 38-year-old male patient who had an isolated intraosseous lipoma with an osteochondral defect in the talus and was treated with autologous osteochondral graft transplantation by medial malleolar osteotomy. He could walk with full weightbearing without any assistance at the end of 12 months. Intraosseous lipoma localized in the talus may be confused radiologically with other bone lesions, especially with unicameral bone cyst, if it is associated with an osteochondral defect. Autologous osteochondral graft transplantation is a successful treatment method for talar intraosseous lipoma. (J Am Podiatr Med Assoc 101(3): 269–274, 2011)

Brown tumor is a benign bone lesion that arises as a direct result of parathyroid hormone on bony tissue in some patients with hyperparathyroidism. Multiple brown tumors may simulate malignant disease and it is a real challenge for the clinicians in the differential diagnoses. Brown tumor as the only and initial symptom of normocalcemic primary hyperparathyroidism is a rare clinical entity. Here, we present a case with multiple brown tumors in a young normocalcemic woman as a sequele of primary hyperparathyroidism mimicking bone metastases. Bangladesh J.

Abstract Background: Quantitative bone SPECT/CT is useful for disease follow up and inter-patient comparison. For bone metastatic malignant lesions, spine is the most commonly invaded site. However, Quantitative studies with large samples size investigating all the segments of normal cervical, thoracic and lumbar vertebrae are seldom reported. This study was to evaluate the quantitative tomography of normal vertebrae using 99mTc-MDP with SPECT/CT to investigate the feasibility of standardized uptake value (SUV) for differential diagnosis of benign and malignant bone lesions. Methods: A retrospective study was carried out involving 221 patients (116 males and 105 female) who underwent SPECT/CT scan using 99mTc-MDP. The maximum SUV (SUVmax), mean SUV (SUVmean) and CT values (Hounsfield Unit, HU) of 2416 normal vertebrae bodies, 157 benign bone lesions and 118 malignant bone metastasis foci were obtained. The correlations between SUVmax and CT values, age, height, weight of normal vertebrae were analyzed. Statistical analysis was performed with data of normal, benign and malignant groups corresponding to same sites and gender. Results: The SUVmax and SUVmean of vertebrae in males were markedly higher than those in females (P<0.0009). The SUVmax of each vertebral segment showed a strong negative correlation with CT values in both males and females (r=-0.89 and -0.92, respectively; P<0.0009). The SUVmax of vertebrae also showed significant correlation with weight and height in males (r=0.4, P<0.0009; r=0.28, P=0.005), and significant correlation with weight in females (r=0.32, P=0.009). The SUVmax of normal group, benign bone lesion group and malignant bone metastasis foci group showed statistical differences in both males and females. Conclusion: Our study evaluated SUVmax and SUVmean of normal vertebrae, benign bone lesion and malignant bone metastasis foci with a large sample population. Preliminary results proved the potential value of SUVmax in differentiation benign and malignant bone lesions. The results may provide a quantitative reference for clinical diagnosis and the evaluation of therapeutic response in vertebral lesions.

The correlations between SUVmax of normal vertebrae and CT values of normal vertebrae, age, height, weight, BMI of patients were analyzed. Statistical analysis was performed with data of normal, benign and malignant groups corresponding to same sites and gender. Results The SUVmax and SUVmean of normal vertebrae in males were markedly higher than those in females (P < 0.0009). The SUVmax of each normal vertebral segment showed a strong negative correlation with CT values in both males and females (r = − 0.89 and − 0.92, respectively; P < 0.0009). The SUVmax of normal vertebrae also showed significant correlation with weight, height, and BMI in males (r = 0.4, P < 0.0009; r = 0.28, P = 0.005; r = 0.22, P = 0.026), and significant correlation with weight and BMI in females (r = 0.32, P = 0.009; r = 0.23, P = 0.031). The SUVmax of normal group, benign bone lesion group and malignant bone metastasis foci group showed statistical differences in both males and females. Conclusion Our study evaluated SUVmax and SUVmean of normal vertebrae, benign bone lesion and malignant bone metastasis foci with a large sample population. Preliminary results proved the potential value of SUVmax in differentiation benign and malignant bone lesions.

Objectives: To investigate the feasibility of intravoxel incoherent motion (IVIM) diffusion MR and diffusion kurtosis imaging (DKI) in discriminating atypical bone metastasis from benign bone lesion in patients with tumors. Methods: Patients with bone lesions in lower extremity suspected of metastases were enrolled in this prospective study. IVIM diffusion MR and DKI were performed before biopsy. Apparent diffusion coefficient (ADC), true diffusion (D), perfusion fraction (f) and perfusion-related pseudodiffusion (D*) were generated with IVIM, while mean kurtosis (MK) and mean diffusion (MD) generated with DKI. Two radiologists blinded to pathology results separately measured these parameters for each lesion through drawing region of interest. Intraclass correlation coefficient was used to determine the inter-reader viability in measurement. The patients with pathology-confirmed metastasis or benign lesion were analyzed. The Mann–Whitney test was used to compare IVIM and DKI parameters between metastasis group and benign lesion group. Receiver operating characteristic curves were constructed to evaluate the ability of discrimination. Results: Bone lesions from 28 patients (metastasis, n = 15; benign lesion, n = 13; mean age = 55 years; age range, 34~77) were analyzed with IVIM and DKI. Intraclass correlation coefficient was greater than 0.8 for all parameters. ADC, D and MD were significantly lower in metastases versus benign lesions (p <0.05). MK and f value were significantly higher in metastases versus benign lesions (p<0.05). D* was not significantly different between the two groups (p>0.05). Areas under curve for ADC, D, f, MK and MD were 0.935, 0.939, 0.891, 0.840 and 0.844 respectively. Conclusions: IVIM and DKI derived parameters distinguish between atypical bone metastasis and benign bone lesion in selected patients with tumors. Advances in knowledge: Bone metastasis and benign bone lesion differ in water molecular diffusion. Intravoxel incoherent motion derived true diffusion distinguishes between atypical bone metastasis and benign lesion.

Osteochondromyxoma is a rare bone tumour. Bone tumours of the talus are also uncommon, and accounts to be between 8% to 23% in tumours of the foot. A 28-year-old man presented with chronic right ankle pain. He had underlying left knee ligament and meniscal injury. Special examination tests for ligament injury were negative. Magnetic Resonance Imaging (MRI) revealed a benign bone lesion of talus with reactive oedema of sinus tarsi. Excision of lesion was done and subsequent histopathological examination confirmed the diagnosis of ostechondromyxoma.
