RESUMO
Peroneal neuropathy is the most common mononeuropathy encountered in the lower extremities. Isolated injuries to the dorsal cutaneous peroneal nerve (DCPN) are uncommon, and most of the reported cases are due to trauma or iatrogenic causes. We report a case of a middle-aged woman who presented with a nine-month history of tingling sensation over the dorsum of her left foot with normal electromyography (EMG) findings and was subsequently diagnosed with entrapment of the DCPN at the ankle by ultrasonographic examination.
RESUMO
Horner syndrome is a constellation of neurological findings consisting of ipsilateral ptosis, miosis, and anhidrosis. Partial Horner syndrome, comprising ipsilateral ptosis and miosis in the absence of anhidrosis, is a well-documented but uncommon manifestation of internal carotid artery dissection. We report the case of a 42-year-old male patient who presented with ipsilateral ptosis and miosis and was subsequently diagnosed with internal carotid artery dissection. In this case report, we discuss the anatomy of the oculosympathetic pathway and the pharmacological diagnosis for a better understanding of the localization of the lesions causing Horner syndrome.
