MR diagnosis of dural venous sinus thrombosis complicating L-asparaginase therapy.

Dural venous sinus thrombosis is an important complication of L-asparaginase chemotherapy. The diagnosis and followup of this condition, using spin echo and fast imaging techniques, is described in three patients. Magnetic Resonance (MR) imaging is a rapid, noninvasive technique for diagnosis and follow-up of this condition. Fast imaging techniques can improve the assessment of these patients.

CT guided lateral C1-C2 puncture.

A technique for CT guided intrathecal contrast material administration via lateral C1-C2 puncture is described as an efficient strategy for evaluation of patients with recent cervical spine injury and quadriplegia.

MR imaging of paraneoplastic limbic encephalitis.

Paraneoplastic limbic encephalitis is a rare disorder that has been previously diagnosed on clinical and pathologic grounds without good radiologic correlation. We present the case of a 42-year-old woman who developed gradually progressive limbic dysfunction 4 years after undergoing mastectomy for breast cancer. Although CT scans were normal, magnetic resonance (MR) imaging showed signal abnormalities in the medial portions of both temporal lobes, the amygdaloid nuclei, and the hypothalamus. An MR-guided temporal lobe biopsy confirmed the presence of encephalitis.

Magnetic susceptibility effects secondary to out-of-plane air in fast MR scanning.

Areas of signal loss in brain overlying air-containing structures at the skull base are commonly observed on axial fast MR images. The nature of this effect, which can mimic the appearance of cerebral hemorrhage, is investigated in a phantom study and in a normal volunteer. The magnitude of the signal loss is found to be inversely related to the distance of the scanning plane from the air-containing structure and directly related to the echo time.
