MR imaging appearances of different types of reconstructive muscle flaps following reconstructive surgery of the lower extremity with associated post-surgical changes due to altered anatomy, radiation, and potential complications, can be challenging. A multidisciplinary therapeutic approach to tumors allows for limb salvage therapy in a majority of the patients. Decision-making for specific typ...

Seven intraparenchymal hematomas (four venous and three arterial) were placed in the brains of six dogs in order to study the MR appearance of acute hemorrhage and to evaluate the effects of several variables on the signal intensity of the hematoma. MR imaging at 0.6 and 1.5 T was performed by using standard short and long TR spin-echo and low-flip-angle gradient-echo sequences. Sequential exam...

BACKGROUND With the aim of identifying common bleeding sites and probable parent vessels in "small" primary pontine hemorrhages, we reviewed computerized tomographic scans of 20 patients with hematomas less than 2.5 cm in diameter. SUMMARY OF REPORT We used scans depicting the upper and lower pons and plotted the centers of the hematomas, assuming them to be a probable source of bleeding. No ...

Hematomas and specimens were studied from 13 surgically-operated chronic subdural hematoma cases. Evacuated hematomas contained elevated potassium ions and slightly increased levels of Acetylcholinesterase (AChE), and the dural specimens including hematoma capsules stained positive for AChE using histochemical methods, especially in the inner membrane of the dura where the Masson Trichrome stai...

Although arachnoid cysts (ACs) are associated with chronic subdural hematomas (CSDHs), especially in young patients, the detailed features of CSDHs associated with ACs remain poorly understood. The objective of this study was to clarify the relationship between the location of CSDHs and ACs and the significance of ACs in young patients with CSDHs. We retrospectively assessed 605 consecutive pat...

Causes of colonic and recto-sigmoid hematomas are multifactorial. Patients can present with a combination of dropping hemoglobin, bowel obstruction and perforation. Computed tomography imaging can provide clues to a diagnosis of intramural hematoma. We present a case of rectal hematoma and a review of current management literature. A 72-year-old male on therapeutic anticoagulation for a pulmona...

Extradural hematoma (EDH) is a frequent lesion, with an incidence varying from 0.2 to 6% in patients admitted to hospital due to traumatic head injury. The higher incidence is found in patients with more severe injuries. The association of EDH with subperiosteal intraorbital hematomas is rarely reported, and we were not able to find in the literature any report of traumatic bilateral intraorbit...

An intramural hematoma is an accumulation of blood between the internal and external elastic membranes within the medial space, whereas an extramural hematoma is a dilution and/or dissemination of blood throughout the adventitia. Intra- and extra-hematomas are observed by intravascular ultrasound during percutaneous coronary intervention (PCI). The patient described herein presented with angina...

Posterior fossa extradural haematoma is known for the vague signs and symptoms and a notorious course that varies from recovery to sudden death. The incidence of posterior fossa epidural hematomas among intracranial epidural hematomas has been reported from 4% to 7%. Subsequently, PFEDH with low GCS or the haematoma of more than 10ml were subjected to evacuation. Since the volume of the posteri...
