Osteopathia Striata with Cranial Sclerosis: Report of Two Cases

Osteopathia striata with cranial sclerosis is a very rare sclerosing bone dysplasia that is characterized by the radiological appearance of longitudinal striations at the metaphysis of the long bones associated with cranial sclerosis. Here, we report a 10-month-old female infant and a 31-year-old male, who were diagnosed incidentally by showing longitudinal sclerotic lines symmetrically in the long bone ends and basal sclerosis of the cranium. The diagnostic linear striation was found not only in the long bones but also in the ribs and phalanges, which are very rare sites for striation. We discuss the radiology findings of osteopathia striata with the possible complication of cranial sclerosis.

MR Imaging of Medullary Streaks in Osteosclerosis: A Case Report

We present a case of medullary sclerosis of the appendicular skeleton in a patient with chronic renal insufficiency for whom MR imaging findings were char-acteristic. T1- and T2-weighted MR images showed multiple vertical lines (medullary streaks) of low signal intensity in the metaphyses and diaphyses of the distal femur and proximal tibia.
