This report describes the pathological characterizations of a rare case of necrosis of the femoral head that was spontaneous, bilateral, avascular and nontraumatic. A 14-month-old beagle dog was presented with pain in the hind limbs. At necropsy, the articular surface in the bilateral femoral head was markedly irregular. There were no gross abnormalities other than in the hip joints. Microscopi...

Knee osteoarthritis (OA) affects the joint beyond just the articular cartilage. Specifically, magnetic resonance imagingidentifiedbone marrow lesions (BML) in the subchondral bone have both clinical and pathophysiological significance.Compared to joint space narrowing on traditional radiographs, the presence of BMLs has been better correlated withseverity of clinical symptoms ...

The objective of this study was to explore the correlation between bone marrow edema, stage of necrosis, and area ratio of necrosis with the hip pain grading in non-traumatic osteonecrosis of the femoral head. Bone marrow edema grading at all levels and the hip pain grade differences were statistically significant (P < 0.001). Bone marrow edema grading increased by levels of 0, 1, and 2, wherea...

Osteomyelitis is an infection-related inflammation of the bones and bone marrow. Generally in legs, arms, spine. Foot ankle osteomyelitis can be excruciatingly painful for patients a difficult management challenge orthopedic surgeons. Acute staphylococcal had 50% death rate pre-antibiotic era. foot occur due to variety reasons, with diabetic infections being one most common. marrow which progre...

Background: Bone marrow is the site of many malignant disorders and it is one of the common places for solid tumors to metastasize. Examination of the bone marrow aspirate and biopsy is a routine procedure performed for assessment of various conditions such as cytopenias, hematologic neoplasms, nonmalignant disorders and metastatic neoplasms. Methods: The patients were referred to the Hema...

Bone marrow necrosis, an uncommon finding in acute lymphoblastic leukaemia, has previously been regarded as a poor prognostic feature. It has been associated with difficulty in establishing the diagnosis, a low rate of remission as well as short remission duration. We report a case of bone marrow necrosis in a girl with acute lymphoblastic leukaemia and good prognostic features who attained com...

In patients with sickle cell disease, hyperhemolysis is a rare but life-threatening complication of transfusion. In this case report, we describe a 61 year-old woman with hemoglobin sickle cell (SC) disease and history of alloimmunization who developed hyperhemolysis associated with a transfusion. She was found to have a warm and a clinically-significant cold autoantibody. Severe anemia (Hb 2.7...

Bone marrow necrosis (BMN) in acute leukemia is a rare histopathological entity at the time of initial diagnosis. However, it represents an important diagnostic and prognostic challenge. Two cases of BMN are reported: a 44-year-old patient with B cell precursor (BCP) acute lymphoblastic leukemia (ALL) and a 27-year-old man with FAB-M5 acute myeloid leukemia (AML) who both presented with bone ma...
