“…In addition, functional imaging is possible to visualize the physiological functions inside the body using the principle of spectroscopy [ 7 , 8 ]. Because of these merits, NIR-TI has been used in clinical practice [ 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 ]. However, the image of a deep-seated structure is blurred severely because of strong light scattering in body tissues.…”

To provide another modality for three-dimensional (3D) medical imaging, new techniques were developed to reconstruct a 3D structure in a turbid medium from a single blurred 2D image obtained using near-infrared transillumination imaging. One technique uses 1D information of a curvilinear absorber, or the intensity profile across the absorber image. Profiles in different conditions are calculated by convolution with the depth-dependent point spread function (PSF) of the transillumination image. In databanks, profiles are stored as lookup tables to connect the contrast and spread of the profile to the absorber depth. One-to-one correspondence from the contrast and spread to the absorber depth and thickness were newly found. Another technique uses 2D information of the transillumination image of a volumetric absorber. A blurred 2D image is deconvolved with the depth-dependent PSF, thereby producing many images with points of focus on different parts. The depth of the image part can be estimated by searching the deconvolved images for the image part in the best focus. To suppress difficulties of high-spatial-frequency noise, we applied a noise-robust focus stacking method. Experimentation verified the feasibility of the proposed techniques, and suggested their applicability to curvilinear and volumetric absorbers such as blood vessel networks and cancerous lesions in tissues.

“…Although no studies on DBFH/DFH imaging have been identified, preoperative MRI, in this case, showed an isotense signal on T1WI, low signal intensity with partial high signal intensity inside the mass on T2WI, and contrast enhancement by gadolinium on the margin of the mass. Benign soft tissue tumors, that frequently occur in the hand, include tenosynovial giant cell tumors, fibromas, lipomas, schwannomas, and hemangiomas [ 9 , 10 ]. Of these tumors, only fibromas show a low signal intensity on T2WI.…”

Soft tissue pseudotumors of the hand and wrist mimicking malignancy: Two case reports

2023

Rationale: Most soft-tissue lesions in the hand and wrist have a benign etiology, and malignant tumors, such as soft-tissue sarcomas, are rare. Mimickers of soft tissue tumors in the hand and wrist are more common than true neoplastic lesions; however, soft tissue pseudotumors that mimic malignancy are very rare. Patient concerns: This study describes 2 patients with soft tissue pseudotumors of the hand and wrist. Both patients presented with rapidly growing soft-tissue masses. Magnetic resonance imaging (MRI) revealed ill-defined margins and an aggressive appearance in both cases, leading to a strong suspicion of malignant soft tissue tumors. Diagnosis: Both patients underwent incisional biopsies, and the final diagnoses were inflammation due to IgG4-related disease in the first case and chronic granulomatous inflammation in the second case. Interventions: The first patient was administered oral steroids, while the second patient was treated with anti-inflammatory drugs. Outcomes: Both patients showed a reduction in swelling of the hand and wrist. Lessons: Although the imaging approach for pseudotumorous lesions is similar to that for true soft tissue tumors, the management of these lesions is different. Biopsies should only be performed when the diagnosis is unclear.
