Concomitant tuberculosis of the iliotibial band mimicking a soft tissue tumor and tuberculous trochanteric bursitis: a case report emphasizing on magnetic resonance imaging findings. Skeletal Radiol 2023; 52:129-135. [PMID: 35943545 DOI: 10.1007/s00256-022-04147-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/20/2022] [Revised: 07/26/2022] [Accepted: 08/03/2022] [Indexed: 02/02/2023]
Abstract
The risk of tuberculosis (TB) increases in immunocompromised patients. Multiple myeloma is considered a risk factor for TB and myeloma patients with TB have a higher mortality rate than those without TB. Herein, we report a case of concomitant TB of the iliotibial band mimicking a soft tissue tumor and tuberculous trochanteric bursitis in a patient with multiple myeloma. In this article, the characteristic magnetic resonance imaging (MRI) findings were low T2 signals in the cystic fluid lesion, a dark T2 signal rim, and peripheral rim enhancement. These results could help differentiate TB of the iliotibial band and trochanteric bursitis from other pathologies. If the abovementioned findings were observed in immunocompromised patients, extrapulmonary TB may be expected even if chest radiographs are normal.

Diagnostics (Basel) 2022; 12:diagnostics12102450. [PMID: 36292139 PMCID: PMC9600497 DOI: 10.3390/diagnostics12102450] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2022] [Revised: 10/08/2022] [Accepted: 10/08/2022] [Indexed: 11/16/2022] Open
Abstract
Arterial spin labeling (ASL) magnetic resonance imaging (MRI) is used to perform perfusion imaging without administration of contrast media. However, the reliability of ASL for musculoskeletal tumors and the influence of post-labeling delay (PLD) have not been fully clarified. This study aimed to evaluate the performance of ASL with different PLDs in the imaging of musculoskeletal tumors. Forty-five patients were enrolled and were divided into a malignant group, a hypervascular benign group, a hypovascular benign group and a control group. The tissue blood flow (TBF) of the lesions and normal muscles was measured and the lesion-to-muscle TBF ratio and differences were calculated. The results showed that both the TBF of lesions and muscles increased as the PLD increased, and the TBF of muscles correlated significantly and positively with the TBF of lesions (all p < 0.05). The TBF and lesion-to-muscle TBF differences of the malignant lesions were significantly higher than those of the hypovascular benign lesions and the control group in all PLD groups (all p < 0.0125) and only those of the hypervascular benign lesions in the longest PLD (3025 ms) group (p = 0.0120, 0.0116). In conclusion, ASL detects high TBF in malignant tumors and hypervascular benign lesions, and a longer PLD is recommended for ASL to differentiate musculoskeletal tumors.

Diagnostics (Basel) 2022; 12:diagnostics12071623. [PMID: 35885528 PMCID: PMC9320678 DOI: 10.3390/diagnostics12071623] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2022] [Revised: 06/26/2022] [Accepted: 07/02/2022] [Indexed: 11/16/2022] Open
Abstract
Appendicular soft tissue lymphoma (ASTL) is rare and is frequently misinterpreted as soft tissue sarcoma (STS). Studies investigating magnet resonance imaging (MRI) characteristics of ASTL are scarce and showed heterogenous investigation criteria and results. The purpose of this study was to systematically review clinical presentations and MRI characteristics of ASTL as described in the current literature. For that purpose, we performed a systematic literature review in compliance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Patient demographics, clinical presentation and MRI imaging characteristics of ASTL were investigated, resulting in a total of nine included studies reporting a total of 77 patients. Signal intensity of lymphoma compared to muscle tissue was mostly described as isointense (53%) or slightly hyperintense (39%) in T1-weighted images and always as hyperintense in proton-and T2-weighted images. Multicompartmental involvement was reported in 59% of cases and subcutaneous stranding in 74%. Long segmental involvement was present in 80% of investigated cases. Involvement of neurovascular structures was reported in 41% of cases and the presence of traversing vessels in 83% of patients. The presence of these findings should lead to the inclusion of ASTL in the differential diagnosis of soft tissue masses.

Value of intravoxel incoherent motion and diffusion kurtosis imaging in predicting peritumoural infiltration of soft-tissue sarcoma: a prospective study based on MRI-histopathology comparisons. Clin Radiol 2021; 76:532-539. [PMID: 33736880 DOI: 10.1016/j.crad.2021.02.014] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2020] [Accepted: 02/11/2021] [Indexed: 12/27/2022]
Abstract
AIM To investigate the performance of intravoxel incoherent motion (IVIM) and diffusion kurtosis imaging (DKI) in the identification of peritumoural infiltration of soft-tissue sarcoma (STS). MATERIALS AND METHODS From July 2018 to January 2020, 34 STS patients who underwent 3-T magnetic resonance imaging (MRI), including IVIM and DKI, were reviewed. The standard apparent diffusion coefficient (ADC), true diffusion (D), pseudo-diffusion coefficient (D∗), perfusion fraction (f), mean kurtosis (MK), and mean diffusion (MD) of each lesion were analysed independently by two observers. An MRI-histopathology control method was used to ensure the correspondence of MRI sections with histopathological sections. Differences in STS with and without infiltration were evaluated. The area under the curve (AUC) was used to determine the best cut-off point for different parameters. Interobserver agreement was assessed using the intraclass correlation coefficient. RESULTS Standard ADC, D, MK, and MD values reliably distinguished STS that had positive and negative infiltration. The MD value had the best diagnostic performance. Use of an MD cut-off value of 2.35 × 10-3 mm2/s to distinguish positive and negative infiltration had an AUC of 0.85, accuracy of 88.2%, sensitivity of 94.4%, and specificity of 81.3%. The two independent observers had nearly perfect agreement for all parameters. CONCLUSION The standard ADC and D value of IVIM, and the MK and MD values of DKI reliably identify the presence of peritumoural infiltration of STS.

Abstract
OBJECTIVE To determine whether the location of a small, indeterminate soft tissue mass within the subcutaneous compartment is related to its histological grade. METHODS All Sarcoma Service referrals over a 12 month period of small (<3 cm) superficial soft tissue masses, indeterminate by MRI evaluation which subsequently underwent primary excision biopsy were included. Lesions were categorised by their anatomical location in the subcutaneous compartment. Histopathological diagnoses were categorized according to12 WHO 2013. χ2 statistical analysis was performed to determine the relationship between lesion depth and histological grade. RESULTS The study included 43 patients, mean age 42 years (range 15-71 years). Within the subcutaneous compartment, 16 lesions were categorized as superficial, 9 lesions central and 18 lesions deep, of which 9 were non-neoplastic, 29 benign, 1 intermediate-grade and 4 malignant. Location in the deep aspect of the subcutaneous compartment was associated with a higher risk of intermediate or malignant histology (p = 0.02). CONCLUSION The location of a small, indeterminate soft tissue mass within the subcutaneous compartment may be an indicator of histological aggressiveness. Lesions in the deep subcutaneous compartment are more likely to be intermediate-grade/malignant lesions. Therefore, if considering excision biopsy as definitive treatment, a wider margin may be appropriate. ADVANCES IN KNOWLEDGE Small, indeterminate soft tissue masses can be aggressive and the anatomical depth within the subcutaneous tissue may be a potential indicator of histological aggressiveness.

Abstract
BACKGROUND AND OBJECTIVE Transilluminated powered phlebectomy using the TriVex system is a new procedure for minimally invasive varicose vein surgery. We used the TriVex system for the removal of benign superficial subcutaneous soft tissue masses, and we also achieved satisfactory clinical effects. The objective of this study was to explore the feasibility, benefits, and technique-related complications of using the TriVex system for the removal of benign superficial masses as a novel and minimally invasive surgical technique. METHOD Between January 2010 and August 2016, 452 patients with benign superficial soft tissue masses underwent surgical removal of masses using the TriVex II system in our department. The surgical complications, postoperative cosmetic outcome, and personal satisfaction were reviewed at a mean follow-up of 24 months. RESULTS The TriVex procedure was successfully completed in all patients using only local tumescent anesthesia without any technical problem and serious complications. The mean operation duration was 8.5 minutes, and the average blood loss was 5 mL. Surgical complications were observed in 69 cases (15.3%) of subcutaneous ecchymosis, 34 cases (7.5%) of skin perforation, 14 cases (3.1%) of subcutaneous hematoma, 13 cases (2.9%) of wound infection, and 7 cases (1.5%) of induration of operation area. Eleven patients (2.4%) showed recurrence during the follow-up and were cured by reoperation by the TriVex system. Overall, the majority of patients (N = 436, 96.5%) were very satisfied or satisfied with the outcome. CONCLUSION The TriVex procedure for the removal of benign superficial masses is simple, safe, and effective with advantages of short operation time, small incisions, and good cosmetic outcome, which is predicted as a new minimally invasive surgery of superficial masses.

Abstract
Superficial solid masses are common conditions in clinical practice, however, some of which can be easily diagnosed and others would be difficult. Although imaging of superficial masses is not always characteristic, it would be helpful to give a definitive diagnosis or narrow a differential diagnosis. Crossing-section imaging can depicture the masses directly, find some pathognomonic signs and demonstrate their relationship with adjacent structures, which can provide decision support for clinician's reference. Computed tomography (CT) can be used to detect calcifications and bone erosion which could not be seen on radiographs. Magnetic resonance imaging (MRI) is the preferred way for evaluating soft tissue lesions and provides information on hemorrhage, necrosis, edema, cystic and myxoid degeneration, and fibrosis. Other advantages of MRI are its superior soft tissue resolution and any profile imaging, which can aid the assessment of extension and adjacent infiltration. Positron emission tomography (PET)/CT and PET/MRI have been increasingly used in bone and soft tissue sarcomas and provides advantages in the initial tumor staging, tumor grading, therapy assessment, and recurrence detection. Therefore, imaging examination can play an important role in treatment decision making for superficial solid tumors. Here we review the important conditions presenting as superficial mass and show the imaging of typical cases diagnosed in our hospital.

[PMID: 28361352 DOI: 10.1007/s00256-017-2635-4] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/11/2016] [Revised: 03/07/2017] [Accepted: 03/14/2017] [Indexed: 02/02/2023]
Abstract
OBJECTIVE Suspected soft-tissue sarcomas are typically investigated using magnetic resonance imaging (MRI), with a view to planning image-guided core needle biopsy for confirmation of the histological diagnosis. Indeterminate superficial lesions may be small and therefore potentially difficult to biopsy safely, such lesions possibly being more amenable to primary excision biopsy. The aim of this study is to determine the suitability of this practice in the setting of a specialist sarcoma service. MATERIALS AND METHODS All patients referred over a 12-month period to the sarcoma service with a small (<3-cm), indeterminate, superficial soft-tissue mass according to MRI criteria, or a small lesion of the hand or foot deemed unsafe for percutaneous biopsy, and who underwent primary excision biopsy were included. The histology results were categorized into neoplastic and non-neoplastic lesions, and assessed for resection completeness. RESULTS Fifty-eight patients fulfilled the inclusion criteria from all patients referred to the sarcoma service in a 12-month period. Of these, 42 out of 58 (72.4%) had benign neoplasms, 4 out of 58 (6.9%) had malignant tumours, 2 out of 58 (3.4%) an intermediate grade lesion, while 10 out of 58 (17.2%) were non-neoplastic. All 4 malignant lesions were completely excised at the time of excision biopsy. CONCLUSIONS Primary excision biopsy of small, indeterminate soft-tissue masses within the setting of a specialist sarcoma service is a suitable management option. Only a small proportion of small superficial soft-tissue lesions with indeterminate MRI features are malignant tumours.
