Purpose To report a unique case of metastatic paraganglioma presenting as a junctional scotoma. Observations A 38-year-old Caucasian man with a history of abdominal paraganglioma presented with minimally blurred vision 20/25 visual acuity in the left eye. The patient was found to have a junctional scotoma upon visual field testing. Cranial MRI revealed a large peri-clival mass compressing the pre-chiasmal optic nerves and other loci of metastatic disease. Intracranial masses, including metastases, can present with a relatively intact central acuity and nonspecific visual symptoms. Conclusions and Importance To the best of our knowledge, this is the first report of metastatic paraganglioma causing a junctional scotoma. In cases with junctional scotoma, careful neuro-ophthalmic assessment and imaging are of paramount importance, even in patients with excellent visual acuity.

“…[10] However, in patients like ours who have a history of extra-adrenal abdominal paraganglioma, reported rates of malignancy have varied between 15% and 35%. [71014] Currently, no microscopic or laboratory criteria exist to reliably predict metastatic potential. However, malignant tumor is more often associated with a greater dry weight of the primary tumor, confluent necrosis, and presence of local invasion.…”

“…[5] Only a few reports of intracranial metastasis for pheochromocytoma exist and to our knowledge, only two other cases of intracranial metastasis have been reported for paraganglioma. [4814] Although Zhang et al . have reported a single case of intraparenchymal involvement of metastatic disease from a paraganglioma, our patient and all other reports of intracranial metastasis demonstrated extra-axial lesions that often involved the skull table.…”

Background:Paragangliomas are tumors of neural crest origin that arise from the extra-adrenal paraganglia. In contrast with the often quoted 10% rule of malignancy for pheochromocytomas, the rate of malignancy as defined by local invasion or distant metastasis has been reported to be from 20% to as high as 50% in some case series with the most common sites of distant metastases being the liver, lungs, and bones. Here we present the case of a patient who presented with a rare case of intracranial metastasis from abdominal paraganglioma.Case Description:Our patient was a 48-year-old male with a distant history of multiple resections of abdominal paraganglioma in 1975 who presented with left shoulder, and left occipital metastasis 35 years after his original paraganglioma operations.Conclusions:Intracranial metastasis of paraganglioma is rare. There are unfortunately no known criteria to assess the risk of metastatic potential and given the long possible latency period between the resection of the primary tumor and the discovery of metastatic disease, patients with paragangliomas require lifelong monitoring. The optimal interval of monitoring has not been elucidated but follow-up every 5–10 years seems warranted.

Influence of the SMA connector and its modeling on electromagnetic simulation

The modeling of subminiature version A (SMA) connectors is occasionally neglected when simulating microwave components or when an approximated model is used to represent its characteristics. In this article, SMA connector modeling is investigated and an appropriate simulation modeling is discussed. It was observed that modeling the inner part of the SMA connector using the coaxial cable model is adequate when no electromagnetic field exist outside of the SMA connector. However, modeling the exterior structure including a receptacle, if it exists, is required when an electromagnetic field exist outside the connector. © 2015 Wiley Periodicals, Inc.
