Spontaneous intracranial hypotension: a study of six cases with MR findings and literature review.

Spontaneous intracranial hypotension is clinically characterized by orthostatic headache and other symptoms caused by low cerebrospinal fluid pressure due to leakage of cerebrospinal fluid from dural punctures or other medical causes. The other symptoms are mainly due to traction of the cranial and spinal nerves owing to descent of the brain caused by low cerebrospinal fluid pressure. Magnetic resonance imaging is very useful in the diagnosis because of its characteristic findings. We describe the MRI findings in six cases that had variable clinical presentation.

MR spectroscopy-aided differentiation: "giant" extra-axial tuberculoma masquerading as meningioma.

Tuberculosis is common in the developing world and in developed nations secondary to increasing immunocompromise in the population. It commonly causes meningitis and parenchymal tuberculomas. We present a case of an unusual masslike "giant" extra-axial tuberculoma during pregnancy. Unusual morphology and size at imaging made meningioma a close differential. MR spectroscopy served to complement MR imaging, providing diagnostic confirmation and depicted findings characteristic of a tuberculoma.

Multiple hemangiomas involving the vertebral column.

Hemangiomas are benign, slow-growing skeletal and soft tissue tumors that commonly involve the bony spine. When found in the spine, they are usually asymptomatic, but can sometimes be associated with local pain and/or neurological deficits. We report the case of a middle-aged Indian male with multiple hemangiomas involving almost all the vertebrae contiguously from C2 to S1 vertebral levels. These were discovered incidentally when a magnetic resonance scan was performed for backache. To the best of our knowledge, such extensive involvement of the spine has not been reported previously.

Bilateral optic pathway glioma with intracranial calcification: magnetic resonance imaging and magnetic resonance spectroscopy findings.

Optic nerve glioma is the most common primary neoplasm of the optic nerve in childhood. It can extend intracranially along the optic pathway (optic pathway glioma). The lesion tends to present with decreased visual acuity in the affected eye, but can cause additional symptoms when it is large. Local involvement within the orbit can be characterized using CT, but MRI is superior in showing the intracranial extent of the lesion. Intracranial calcification in optic pathway glioma is rare. We present a rare case of optic pathway glioma with calcification in the intracranial component. Also, we describe MR spectroscopy (MRS) findings in this case.
