Cardiac Silhouette

A 47-year-old woman presented with shortness of breath, chest discomfort, and hoarseness. She was found to have an enlarged cardiac silhouette on plain chest radiography. Computed tomographic scan and magnetic resonance imaging were diagnostic of a giant pericardial cyst. The patient underwent successful videoscopic removal of the cyst with complete resolution of her symptoms.

Possible Cause

Abstract We report the case of a 61-year-old man in whom numbness developed on the right side of the penis, scrotum, and perineum after he jumped into a swimming pool. Magnetic resonance imaging and a computed tomographic scan disclosed a lesion at S1-S2 impinging on the right S2 nerve root. At surgery, ruptured disc material originating in an area normally occupied by the fixed fibrocartilaginous plate was identified and excised. Postoperatively, the numbness resolved. We discuss a possible cause of the rupturing of the sacral disc and recommended treatment by laminectomy and excision, as in other cases of ruptured disc at other levels of the spinal column.

Abstract Single-fraction, closed skull, small-volume irradiation (radiosurgery) of intact intracranial structures requires accurate knowledge of radiation tolerance. We have developed a baboon model to assess the in vivo destructive radiobiological effects of stereotactic radiosurgery. Three baboons received a single-fraction, 150-Gy lesion of the caudate nucleus, the thalamus, or the pons using the 8-mm diameter collimator of the gamma unit. Serial standard neurodiagnostic tests (neurological examination, computed tomographic scan, magnetic resonance imaging, stable xenon-enhanced computed tomographic scan of cerebral blood flow, somatosensory and brain stem evoked potentials, and myelin basic protein levels of cerebrospinal fluid) were compared with preoperative studies. Magnetic resonance imaging revealed the development of a lesion at the target site between 45 and 60 days after irradiation. Deterioration of the brain stem evoked potentials preceded imaging changes when the lesion encroached on auditory pathways. Myelin basic protein levels increased subsequent to imaging changes. Postmortem neuropathological examination confirmed a well-demarcated radionecrosis of the target volume. The baboon model appears to be an excellent method to study the in vivo biological effects of radiosurgery.

Abstract The authors have treated a 20-year-old man with a dorsal intramedullary epidermoid cyst in whom magnetic resonance imaging was performed both before evacuation of the cyst and 3 months later. Intraspinal epidermoid tumors are rare, and the intramedullary location is quite uncommon. To our knowledge, this is the first description of magnetic resonance imaging of an intramedullary epidermoid cyst. The frequency, possibilities, and limits of surgical treatment of such intraspinal benign tumors are reviewed.

Periodic Examination

Abstract Four patients with macroprolactinomas treated with bromocriptine had tumor growth and visual loss despite marked reduction in their serum prolactin levels. Explanations for this dissociation of tumor growth and prolactin measurement might include noncompliance. Patients treated with bromocriptine require periodic examination by computed tomographic scan or magnetic resonance imaging and neuro-ophthalmological evaluation in addition to monitoring of serum prolactin.
