Intramuscular hematoma at buttocks as a result of a sports injury Left to right: Epidural, subdural, and intracranial hematoma of the brain Hematoma of the ankle caused by a 3rd degree sprain. Subdermal hematoma (under the skin) Intramuscular hematoma (inside muscle tissue) Skull/brain: Subgaleal hematoma – between the galea aponeurosis and ...
Subgaleal hemorrhage, also known as subgaleal hematoma, is bleeding in the potential space between the skull periosteum and the scalp galea aponeurosis (dense fibrous tissue surrounding the skull). Symptoms
The differential diagnosis includes many tumoral and nontumoral pathologies. A main concern is to differentiate early myositis ossificans from malignant soft-tissue tumors, and the latter is suggested by a fast-growing process. If clinical or sonographic findings are dubious and extraosseous sarcoma is suspected, biopsy should be performed.
Hematomas have solid adrenal nodules, size of which are comparable to soft tissue and diminish over time. Partially solid and partially cystic lesions can present in many adrenal abnormalities. Compared to neoplasm, hematomas show higher density in pre-contrast scans with solid components tending to locate peripherally while fluid locating ...
Medical ultrasonography of a soft tissue lump, showing signs of a suspected malignant lymph node: [15] - Doppler ultrasonography that shows hyperaemic blood flow in the hilum and central cortex and/or abnormal (non-hilar cortical) blood flow - Increased focal cortical thickness greater than 3 mm - Absence of the fatty hilum
Heterotopic ossification of varying severity can be caused by surgery or trauma to the hips and legs. About every third patient who has total hip arthroplasty (joint replacement) or a severe fracture of the long bones of the lower leg will develop heterotopic ossification, but is uncommonly symptomatic.
The hematoma can exert a mass effect on the brain, increasing intracranial pressure and potentially causing midline shift or deadly brain herniation. In the past this effect held additional diagnostic importance since prior to the invention of modern tomographic soft-tissue imaging utilizing MRI or CT it was not possible to directly image many ...
Chorionic hematoma is the pooling of blood between the chorion, a membrane surrounding the embryo, and the uterine wall. [2] It occurs in about 3.1% of all pregnancies , [ 2 ] it is the most common sonographic abnormality and the most common cause of first trimester bleeding .
