Rosai-Dorfman disease with paravertebral and epidural thoracic spine involvement: A case report and literature review.

Rosai-Dorfman disease (RDD) with spinal cord involvement is a rare clinical entity. We report a case of RDD with paravertebral and intraspinal epidural involvement in a 24-year-old male Bangladeshi patient who presented with progressive bilateral lower limb weakness for 20 days duration associated with spasticity and muscle spasm. MRI demonstrated an enhancing paravertebral soft tissue lesion extending from C7 through T4 with intraspinal epidural extension encasing the spinal cord with focal cord oedema.

Rare case of multiple aggressive vertebral hemangiomas.

A case of a 42-year-old man with back pain associated with left radiculopathy and infiltrative mass involving the T12 and L5 vertebrae is described. Magnetic resonance imaging (MRI) and computed tomography indicated aggressive hemangiomas involving the T12 and L5 vertebrae. Three-year follow-up by imaging indicated minimally increased aggressiveness of the L5 lesion without any significant change in appearance of the T12 lesion thus, confirming the initial diagnosis of multiple aggressive vertebral hemangiomas.

Smaller anterior cruciate ligament diameter is a predictor of subjects prone to ligament injuries: an ultrasound study.

Purpose: To test if diameter of normal anterior cruciate ligament (ACL) can be measured by ultrasound (US), to see if there is a relationship between smaller ACL diameter and ACL injury, and to assess agreement between radiologists in measuring ACL diameter in cases and matched controls.

Materials And Methods: In this ethics committee-approved study, maximum diameter of ACL near tibial insertion site was measured by static and dynamic US study in 25 normal contralateral knees of subjects who suffered noncontact ACL injury and in 25 matched control subjects.

Results: ACL was visualized as a thick linear hypoechoic band inserted approximately 11 mm caudal to the tibial plateau and the intercondylar eminence.

Magnetic resonance imaging features of brain and spinal cord injury in a fatal case of isopropanol intoxication.

A 60-year-old man presented with headache, dizziness, and disorientation one day after consumption of isopropanol along with ethanol. Computed tomography (CT) of the brain performed immediately was unremarkable. The patient collapsed within the hospital 30 minutes after the CT scan was done, and remained comatose until death, showing no improvement with symptomatic treatment.
