Radionuclide scan findings in delayed splenic rupture.

An initial liver/spleen scan performed on a patient with blunt abdominal trauma was negative 3 days following the accident. A follow-up scan 7 days later showed definite evidence of splenic rupture, proved surgically. The authors conclude that, in such cases, spleen scans may be negative initially because of delayed splenic ruptures.

MRI in hyperparathyroidism requiring reoperation.

A 34-year-old woman presented with persistent hyperparathyroidism (HPT) following primary surgical removal of a hypertrophied parathyroid gland. Reevaluation ultrasound (US), computed tomography (CT), and parathyroid scintigraphy studies were negative for parathyroid adenoma. Magnetic resonance imaging (MRI) clearly identified an ectopic parathyroid adenoma within the lateral carotid sheath. Uncomplicated surgical extirpation of the adenoma was accomplished. We discuss the role of US, CT, parathyroid scintigraphy, and MRI in recurrent HPT.

MR imaging of unusual chordomas.

Chordomas are uncommon primary skeletal neoplasms arising from notochordal remnants. Approximately 50% arise in the sacrum, 35% in the clivus, and less than 15% in the true vertebrae. We report magnetic resonance (MR) studies of four unusual primary chordomas, three in the lumbar region (L1, L2, and L3) and one in the Meckel cave. It is often difficult to differentiate the MR findings of these four tumors from other common neoplasms.

MR findings of an unusual intracranial neuroma simulating a meningioma.

We report an unusual intracranial neuroma that simulated a meningioma on CT and magnetic resonance imaging. A diagnosis of meningioma was suggested because the tumor was tentorium-based; had enlarged into both the middle and posterior fossae; contained calcification and was homogeneous and densely enhancing on contrast CT; and was isointense with brain on T1- and T2-weighted images. The tumor proved to be a schwannoma with characteristic electron microscopic findings.

Lumbar epidural chordoma: MR findings.

Chordomas derive from persistent nests of notochordal cells that do not regress. They usually arise from the midline within bone of the skull base or spinal column. Typical radiographic findings of chordomas include midline location and bony destruction. We report an unusual epidural chordoma of the lumbar spine.

Neurilemoma of the tongue: MR findings.

Neural tissue tumors of the oral cavity are rare. They are found most commonly in the tongue and arise from the sheaths of peripheral nerves, neuroglia, and neurons. We report magnetic resonance findings in a case of neurilemoma of the tongue.
