Bleeding around the sheath is rarely seen but can occur after difficult arterial access, excessive anticoagulation, or exchange for a smaller sheath. (B) Transverse image of an intramuscular hematoma (asterisk) of the right adductor longus with color (CD) and pulsed wave (PWD) Doppler, demonstrating pulsatile, arterial flow within the hematoma. Methods: Cellulite dimples were examined on the bilateral thigh and buttock regions of 50 consecutive women and each dimple was scored with the Hexsel Cellulite Scoring System based on severity. A 95-year-old female underwent transurethral resection of the bladder tumor. 6. We retrospectively reviewed 2 cases of organizing hematomas and 2 cases of intravascular organizing thrombi and investigated correlations between sonographic and pathologic findings. Hematoma is a consideration when soft tissue?? If the ultrasound study is inconclusive, a CT scan is the next test. The hematoma shows a heterogeneous, hypoechoic, pseudosolid appearance.

After 4 days, the patient was taken to theatre for debridement, and the wound was washed out. The mass was soft and has a smooth surface with normal overlying skin. The judicious use of ultrasound allows for more appropriate patient care and management of their underlying infection. When an obturator nerve block (ONB) is performed, the conventional landmark method or ultrasound-guided method is used. Ultrasound using a high-frequency sensor for surface parts. Many benign masses have charac - Ultrasound using a high-frequency sensor for surface parts. Given the diagnostic doubt, the patient underwent skin ultrasound with a 15-18-MHz linear probe (Esaote MyLab), which revealed the presence beneath the sternocleidomastoid muscle of a hypoechoic, oval structure (2.8 × 1.5 × 1.4 cm) with well-defined margins and a major axis in .
