Melorheostosis involving the cervical and upper thoracic spine: radiographic, CT, and MR imaging findings.

Melorheostosis, an uncommon mesenchymal dysplasia, rarely affects the axial skeleton. We describe the imaging findings of melorheostosis involving the cervical and upper thoracic spine. Radiographs and CT showed unilateral well-marginated undulating zones of cortical hyperostosis involving multiple vertebrae that were contiguous with a coalescent ossified right paravertebral mass. MR imaging showed zones of signal intensity void on all pulse sequences without contrast enhancement. Conservative management was elected because of lack of interval clinical and imaging changes for 8 years.

[Melorheostosis, osteopoikilosis and ostiopathia striata. Their clinical significance and the value of scintigraphy in the differential diagnosis].

Melorheostosis, Osteopoikilosis and Osteopathia striata Clinical Relevance and Bone Scintigraphy Melorheostosis, Osteopoikilosis and Osteopathia striata are rare conditions. Although there is no casual therapy for any of the three diseases, differential diagnosis is important because concomitant or resulting impairments deserve orthopaedic or medical treatment. The analysis of typical cases with their clinical, roentgenological and radionuclide presentation shows the need of an accurate diagnosis to prevent senseless treatment or lost therapeutic opportunities.

Melorheostosis: two case presentations and review of the literature.

Two cases are presented. Case #1, a 27-year-old Caucasian male presented with chronic right leg pain. Case 2 was a 23-year-old Caucasian female with right fifth finger pain. The clinical examination was benign except for mild tenderness of many years duration. No deformities were present in the male patient, the female patient did exhibit mild clinodactyly. The pain was described as constant, low grade, and dull. Plain roentgenograms of both patients demonstrated a hyperostotic process typical of melorheostosis and the bone scans demonstrated increased bone activity. A CAT scan demonstrated both endosteal and periosteal hyperostosis in our male patient. The biopsies of both patients were consistent with the clinical diagnosis of melorheostosis. A discussion and review of the literature covering this process is presented.

Successful symptomatic treatment of melorheostosis with nifedipine.

Melorheostosis is an unusual sclerotic dysplasia of bone. We describe a patient with melorheostosis who showed improvement in pain and vasomotor function after treatment with nifedipine. Peripheral vascular disturbances may be responsible for the pain associated with this disorder and vascular abnormalities could possibly be related to the pathogenesis of this disease.

[A case of melorheostosis. Clinical, radiological, pathological and biomechanical details].

A patient with melorheostosis of the right lower limb is described with the clinical findings and radiographic appearances which include angiographs and microradiographs. Tissue was taken from the knee joint at the time of arthrodesis and examined by histological, histochemical and biomechanical techniques. It is concluded that the bone in melorheostosis is not different from normal bone.

Melorheostosis and rheumatoid arthritis.

A 63-year-old woman presented with the clinical picture of classical rheumatoid arthritis. X-ray examination also showed typical aspects of melorheostosis involving both femurs by linear hyperostosis. Humoral and bone scan findings were all in keeping with rheumatoid arthritis. Moreover, a reduced renal phosphate reabsorption and hypophosphatemia were found along with mild hypercalcemia and hypercalciuria. No evident relationships among rheumatoid arthritis, melorheostosis and renal phosphate handling were observed in this case.

Melorheostosis of the foot: a case report and review of the literature.

As seen in the case presented, melorheostosis is a bony dysplasia showing irregular wavy lines of hyperostotic bone. Clinically, patients present variably, ranging from incidental radiographic discovery of the syndrome to severe deformities and pain. Subsequently, diagnosis is often delayed or missed. Treatment is usually symptomatic, although surgical correction of deformities is often pursued. Unfortunately, these surgeries may be complicated with frequent vascular problems and deformities usually recur. Thus, treatment of melorheostosis should be individualized based on the patient's lifestyle, progression of disease and age.

Melorheostosis.

Melorheostosis is a rare, benign connective-tissue disorder characterized by a cortical thickening of bone with irregular dense hyperostosis that appears to flow along the cortex. We review the literature to date, etiology, clinical aspects, roentgenographic features, histology, and treatment of melorheostosis.

Brief communication: a possible case of melorheostosis from antiquity.

An unusual case of discontinuous hard tissue hyperostosis is described in a 25-30-year-old female dating between 4000 and 5500 BP from northern Chile. This specimen was one of 104 individuals examined from the Morro-1 site, which is known to represent the Chinchorro culture. The only other reported case from antiquity dates to 500 AD (Lester [1969] J. Bone Joint Surg. [Am.] 49:142-143). A review and comparison of this case to the medical literature supports a diagnosis of melorheostosis. Differential diagnosis is presented with the ruling out of nonspecific manifestations of osteomyelitis/periostitis as the most likely alternative diagnosis.

Melorheostosis: presentation of a case followed up for 24 years.

The case of a woman affected by Melorheostosis of the left arm, who was followed for 24 years, is presented. After a brief review of the main clinico-radiological features and the most likely pathogenetic theory, the authors point out the slow but inexorable progression of the alterations and their localization, which is strictly limited to the dermatome supplied by a spinal nerve.

Melorheostosis of the hand in a 7-year-old girl.

Melorheostosis of the hand is rare. We report a 7-year-old girl who presented with a contracture of the left hand. Diagnosis was made by conventional radiography and bone scintigraphy. MRI proved to be a very useful tool to visualize the soft-tissue changes. This is especially important when surgical repair is considered.

Magnetic resonance imaging depiction of tight iliotibial band in melorheostosis associated with severe external rotation deformity, limb shortening and patellar dislocation in planning surgical correction.

We present the case of a 14-year-old male with melorhesotosis and severe iliotibial band tightness which was associated with femoral shortening, severe external rotational deformity of the femur, genu valgum and patellar dislocation in the right lower extremity. Skeletal survey revealed irregular radiodense streaks involving the pelvis, femoral head, femoral shaft, distal femoral epiphysis, talus and middle phalangeal bones of the foot. Magnetic resonance (MR) imaging showed thickening of the iliotibial band in addition to low MR signal changes in the bone. Intraoperatively fibrosis in the subcutaneous layer and a thickened iliotibial band were found. MR images were very useful in understanding the soft tissue pathoanatomy in melorheostosis and planning surgical correction.

Atypical form of active melorheostosis and its treatment with bisphosphonate.

We present the case of a 38-year-old man in whom extensive bilateral melorheostosis was associated with elevated serum alkaline phosphatase, swelling of the right foot and progressive deformity of the left hand, left leg and right foot. Radiography, computed tomography and bone scintigraphy were performed. Following treatment with bisphosphonate (30 mg/day of pamidronate for 6 days) infusion, the pain and swelling of his right foot showed improvement and his elevated serum alkaline phosphatase decreased.
