Hip pain due to aseptic necrosis of the femoral head was the first clinical manifestation of chronic myelogenous leukemia in a 9-year-old white female. An erroneous diagnosis of rheumatoid arthritis was first entertained. Physical examination showed splenomegaly, complete blood count revealed leucocytosis of 359,000. The initial radiograph of the involved hip was negative. Biopsy revealed aseptic necrosis of the femoral head. Chronic myelogenous leukemia (CML) was diagnosed on the basis of the peripheral blood smear and bone marrow biopsy. Two months later, radiograph, radionuclide bone scan, and magnetic resonance imaging (MR) of the involved hip were positive for aseptic necrosis of the femoral head.

A 42-year-old man with chronic myelogenous leukemia presented to the hospital with hip pain. After undergoing surgical repair for a hip fracture, he developed aphasia, facial droop and fever. He was initially diagnosed with a stroke. A lumbar puncture excluded common infections, and an ELISA test for HIV was negative. Serial MRI scans revealed a progressive demyelinating pattern. Polymerase chain reaction performed on cerebrospinal fluid was positive for the JC virus (JC are the initials of the first person diagnosed with this virus). The patient was treated with cidofovir but died before a full course could be administered. JC virus is present in most adult hosts but is only harmful in immuno-compromised hosts. The active form of the disease is known as progressive multifocal leukoencephalopathy. This is the first reported case of a patient developing progressive multifocal leukoencephalopathy. with chronic myelogenous leukemia as the only underlying condition.

A 27-year-old male patient presented with right-sided hip pain. Magnetic resonance imaging of the hip joint revealed an extensive intrapelvic mass adjacent to the iliopsoas muscle. Laboratory tests showed severe leukocytosis and a differential WBC count enabled the diagnosis of chronic myeloid leukemia (CML). The pelvic mass was then assessed as granulocytic sarcoma developing from CML. It should be kept in mind that the initial presenting feature of hematological diseases such as CML may be hip pain arising from CML-associated granulocytic sarcoma.

Pyomyositis is a pyogenic muscular tissue infection mainly occurring in immunocompromised patients. Chronic myeloid leukemia (CML) accounts for only 2-3% of cases of childhood leukemia. Herein, we report on a 17-year-old male with bilateral hip pain caused by adductor pyomyositis before beginning the treatment course of CML. CML was diagnosed by bone marrow chromosome study and was treated initially with imatinib but switched to hydroxyurea 5 days later because of poor cytoreduction response. Subsequently, white blood cell counts decreased gradually; however, the hyperleukocytosis condition resolved very slowly again until we switched back to imatinib use on the 40(th) day of hospitalization. Pyomyositis was diagnosed by magnetic resonance imaging. Oxacillin was administered to cover Staphylococcus aureus, the most common pathogen of pyomyositis. Bilateral hip pain improved within 72 hours after antibiotic usage, but follow-up magnetic resonance imaging after 15 days of treatment revealed well-defined abscess and osteomyelitis of both femoral heads. Abscess incision and drainage were performed, and cultures of the drained pus grew no microorganisms. The patient completed 5 weeks of oxacillin treatment after the operation and recovered with a full range of motion of both hips. There was no residual disability. This is the first report of bilateral hip pain caused by pyomyositis as the initial presentation of CML. Pyomyositis needs to be considered in the differential diagnosis of hip pain in pediatric patients.

A 12-year-old female is reported who presented with right hip pain for 6 months. With massive splenohepatomegaly and leukocytosis, CML was suspected and confirmed on bone-marrow examination and cytogenetics. Further investigations confirmed avascular necrosis (AVN) of the right femoral head. CML was treated by hydroxyurea, followed by imatinib. AVN was managed conservatively; patient demonstrated progressive improvement, though a mild limp in the gait was persisting at 22 months. AVN as the initial manifestation of CML is a rarity. Leukostasis is considered to be the pathophysiological mechanism. In view of the rarity, a case is reported, along with compilation of previously reported cases.
