Purpose: To report our experience using a multilevel patient management algorithm to direct transarterial embolization (TAE) in managing spontaneous intramuscular hematoma (SIMH). Materials and methods: From May 2006 to January 2014, twenty-seven patients with SIMH had been referred for TAE to our Radiology department. Clinical status and coagulation characteristics of the patients are analyzed Hematoma. Hematomas (alternative plural: hematomata) are the name given to localized collections of blood and they can form virtually anywhere in the body. They often form secondary to trauma or surgery but spontaneous formation is also not uncommon, especially in those with coagulation disorders or on anticoagulant therapy Hematomas are abnormal collections of blood outside of a blood vessel. Damage to the wall of the vessel causes leakage of blood into tissues that can be irritating and cause pain, tenderness, and swelling. intramuscular hematoma or seroma, osteomyelitis. 9; Consider CT angiogram of affected extremity if equivocal pulse examination. In intermuscular hematoma the muscle fascia looks damaged thereby allowing the extrava‐ sation of blood flow between muscles and fascia. This causes the formation of a more or less wide livid and swelling area. Contrary to the intramuscular hematoma, the intermuscular hematoma causes a painful symptoms limited to the first 24 hours post-trauma Intramuscular hematomas may also occur in the absence of trauma, either spontaneously or in patients who are receiving anticoagulation therapy . The former, however, may be due to an underlying soft-tissue mass, and therefore a spontaneous hematoma should be followed up with serial imaging to document complete resolution and exclude underlying.

Although there is no grading for an oblique muscle hematoma because of its rarity, the following grading system has been established for a rectus sheath hematoma on the basis of CT findings. Grade I is an intramuscular hematoma with an observable increase in muscle size The hematoma visible on the CT angiography is contained in front of the sheath at this level. Below the arcuate line, the posterior sheath disappears, leaving the transversalis fascia as the only interface with the abdominal cavity. The hematoma at this level cannot be contained and fuses in the abdominal cavity (b) on the scan The intramuscular hematoma is characterized by the integrity of epimysium and by blood extravasation into the body of the muscle affected by the trauma. This causes an increasing of the intramuscular pressure with consequent compression of the capillary bed, which contrasts the bleeding; therefore clinical signs and symptoms remain localized Intramuscular hematomas are diagnosed by computed tomography (CT) and magnetic resonance (MR) imaging. Most hematomas resolve spontaneously without clinical complications, if the hematoma is not large, or it is not compressing the surrounding important structures. Moreover, some hematomas gradually grow for months and years Disorder of soft tissue 19660004. Soft tissue lesion 239953001. Intramuscular hematoma 262969000. SNOMED CT Concept 138875005.

tion of his physical therapy. A repeat CT scan revealed a recurrent 18 cm intramuscular fluid collection with vessel enhancement and mild fat stranding. A second incision and drainage was performed with evacuation of approximate-ly 1300 mL of old hematoma; cultures were sent at that time and the patient was discharged home. Unfortunately Although conservative management is sufficient for patients with neurologic impairment, needle aspiration after autolysis of the hematoma, which can be confirmed by computed tomography (CT), is also recommended (4) I. INTRODUCTION. Spontaneous muscle haematoma (SMH) is an uncommon condition often overlooked or misdiagnosed (), and potentially life-threatening, particularly in frail and elderly patients.For a quick diagnosis and to choose the best treatment, a high degree of suspicion is necessary especially in patients with acquired coagulopathy (e.g., oral anticoagulant therapy)

Intramuscular hematoma (Concept Id: C0240412) Blood clot formed within muscle tissue following leakage of blood into the tissue CT and angiograms were reviewed for the location of the hematoma, the presence of extravasation, and the correlation of CT and angiography findings.ResultsArterial extravasation was present on 34/39 CT scans. Angiograms confirmed the CT scans in 29 cases CT has become an integral part of the evaluation of patients with blunt abdominal trauma. CT has been shown to be accurate in defining solid and hollow visceral injuries as well as associated hemoperitoneum [1,2,3].With the increasing use of contrast-enhanced CT in the emergency setting, a number of authors have reported their experiences using CT to detect active abdominal hemorrhage in. The intramuscular hematoma causes severe pain, muscle dysfunction, and occasionally nerve palsy with the femoral nerve most commonly affected. Most patients are neurologically normal but when a significant neurological deficit is associated with iliopsoas hematoma, optimal treatment recommendations vary Computed tomography (CT) and magnetic resonance imaging (MRI) revealed intramuscular hematoma and intracranial hemorrhage. The results of initial coagulation studies were normal, but repeated coagulation studies revealed an isolated prolongation of the aPTT. Additional laboratory tests confirmed the diagnosis of acquired hemophilia A

Use of CT in Emergency Care. Newer generations of multidetector CT scanners have improved temporal and spatial resolution, which results in improved recognition of active extravasation (, 2) (, Fig 1,).Because of these technical improvements, CT is performed earlier in the work-up of a stable polytrauma patient (, 3 4).Decreasing the transit time from the site of the initial injury to the. Spontaneous intramuscular hematoma of the abdomen and pelvis (SIMH) is a rare complication of ACT . The word spontaneous refers to hematomas that they do not have any relation with trauma or surgery in the last 3 weeks or with an underlying muscle disease (e.g., tumor) The CT should be performed without contrast and then with contrast. Intramural hematoma can actually be better visualized without contrast as blood is bright when the bleeding is acute. On the contrast exam, the hematoma may blend into the wall and seem like an atherosclerotic process A high intramuscular pressure due to contusion with hematoma developed in the thigh of 2 athletes after moderate blunt muscle trauma. The pain became severe a few hours after the trauma. In both patients a fasciotomy and evacuation of the hematoma was performed.

Intramuscular angiomas are uncommon and account for approximately 0.8% of all benign soft tissue tumors, but are one of the more frequent deep-seated soft tissue tumors. There is a peak in young adults and adolescents but they are found in a wide age range and many are presumed to be congenital. There is no gender predilection 1,2 Chronic expanding hematoma is characterized by continuous growth of a blood collection. We analyzed the clinical features of 7 patients with chronic expanding hematomas in the extremities, with an average age of 65.6 years. All lesions occurred in the lower extremities, with 4 seen in the thigh and 3 in the knee region. Six patients had subcutaneous hematomas, while 1 was deep-seated in the thigh

A computed tomography (CT) scan with IV contrast of the right lower extremity was performed on admission and showed a 15 cm complex encapsulated fluid collection in the right posteromedial thigh (Figure 1). Imaging findings and history were consistent with an intramuscular hematoma thought secondary to a hamstring rupture D-dimer, were unremarkable. An enhanced leg CT revealed a hematoma in the left gastrocnemius muscle (Pic-ture B, C, arrows). The etiology of spontaneous unilateral calf swelling var-ies. It is important to quickly discriminate between deep vein thrombosis and intramuscular hematoma because the treatments for these disorders are different (1. Intermuscular Hematoma. Bleeding may occur between muscles when a muscle fascia and its adjacent blood vessels are damaged. After an initial increase, causing the bleeding to spread, the pressure falls quickly. Typically, bruising and swelling, caused by a collection of blood, appear distally to the damaged area 24-48 hours after the injury.

The Hb level dropped from 12.3 g/dL to 7.4 g/dL. A cerebral CT examination of the patient was interpreted as normal. The abdominal CT revealed a large organized hematoma, 210x182x142 mm in diameter, in the lower half of the inferior rectus towards the retroperitoneal area (Fig. 3).

It is similar to (and sometimes indistinguishable from) a hematoma, commonly called a bruise, though the terms are not interchangeable in careful usage. The natural process of healing a fracture starts when the injured bone and surrounding tissues bleed, forming a fracture hematoma. It can be injected intravenously or subcutaneously (under the skin); intramuscular injections (into muscle) are. Psoas muscle hematoma is defined as a spontaneous or traumatic retroperitoneal collection of blood involving the psoas muscle. Early symptoms of an iliopsoas hematoma include lower abdominal or severe groin pain. Although psoas hematoma is a known complication of coagulopathy, psoas hematoma caused by non-penetrating trauma is the subject of only scattered reports and its significance has not. Hematomas are a collection of blood outside of a blood vessel. There are several types of hematomas, which are often described by their location (for example, under the fingernail, in the liver, spine, and ear). The most common type of hematoma is due to trauma.

Baker cyst hematoma and its diagnosis and management. KEY WORDS: Calf; hematoma; spontaneous; tenderness INTRODUCTION Haematoma is a collection of blood that is confined to an organ, tissue or space, and is caused by a break in a blood vessel. Haematoma usually occurs after a traumatic event, surgery or from a pre-existing vascular defect. However, th Shallow intramuscular hematomas are removed by opening the formation, ligation of the bleeding vessels and stitching. Such uncomplicated hemorrhages have a favorable prognosis. Intracranial hematoma is removed by resection and osteoplastic craniotomy, in which blood clots are removed through a mouthpiece. Hematoma must be removed completely The differential of a spontaneous hematoma must also include intramuscular aneurysm, intramuscular hemangioma, chronic expanding hematoma and soft tissue malignancy, such as sarcoma or (rarely) soft tissue carcinoma metastases. A history of bleeding tendencies also may increase the chance for a true spontaneous hematoma

Non-contrast CT of the pelvis and lumbar spine showed a moderate sized right iliopsoas hematoma and a small amount of retroperitoneal bleeding, consistent with iliopsoas muscle rupture. Orthopedic surgery recommended admission and a type and screen and PT/INR, which was within normal limits. Image 1. Hematoma and retroperitoneal bleed. Image 2 Spontaneous retroperitoneal hematoma (SRH) is defined as bleeding into the retroperitoneal space without trauma or iatrogenic manipulation [ 1 ]. Rectus sheath hematoma (RSH) results from accumulation of blood within the rectus sheath. Both conditions are rare but may mimic a number of acute intra-abdominal pathologies, warranting heightened. The CT appearance depends on the lesion's age. Acute blood is hyperdense, but subacute hematomas demonstrate mixed density, reflecting clot lysis. The rim may enhance after contrast administration .
