It is unclear whether hypertension (HTN) is a predisposing factor for the development of trigeminal neuralgia (TN). The purpose of this study was to determine the prevalence of HTN in TN patients and controls at the USC Orofacial Pain and Oral Medicine Center. A retrospective chart review was conducted from a database of over 3,000 patient records from 2003 to 2007. We identified patients diagnosed with TN with or without HTN. A total of 84 patients (54 females; 30 males) between the ages of 33 and 93 years were diagnosed with TN; 37% had TN with HTN and 32% of controls had HTN. The increased prevalence of HTN in the TN patients was not statistically significant (P = 0.50). Since, both TN and HTN are seen in the elderly, it is likely that HTN is simply a co-existing condition in patients with TN and not a risk factor for its development.

A 21-year-old man developed idiopathic trigeminal neuralgia, and was admitted to our hospital. Although neuralgia was promptly resolved after oral carbamazepine (CBZ) administration, he developed arterial hypertension (from 110/60 mmHg to 170/126 mmHg) followed by consciousness disturbance several days after the initiation of carbamazepine. MRI T2-weighted, FLAIR and ADC images demonstrated transient hyperintense lesions of the bilateral fronto-parieto-occipital subcortical white matter. These lesions showed isointensity on diffusion-weighted images. Since these alterations suggested the presence of vasogenic edema induced by hypertension, we diagnosed him as having reversible posterior leukoencephalopathy syndrome (RPLS) induced by hypertension. Persistent hypertension despite the administration of various anti-hypertension drugs finally improved after oral CBZ therapy was discontinued. Therefore, we considered that hypertension was induced by oral CBZ therapy. This is a rare case in which high blood pressure was caused by CBZ. There is no previous report of RPLS induced by CBZ administration. Further investigation to determine whether CBZ is capable of causing arterial hypertension is warranted.

Headache is a common presenting complaint in most family physicians' practices. Anxiety and depression (the ache of living) are at the root of most cases. A significant minority suffer from vascular headaches and a few cases harbor organic lesions.Headaches due to eyestrain, sinusitis, trigeminal neuralgia and hypertension are greatly overdiagnosed. The precise diagnosis of all cases of headache is important in choosing the appropriate therapy. Often the greatest benefit achieved is the discontinuation of inappropriate and potentially harmful treatment or self-medication.

Common complications of neurolytic mandibular nerve block are hypoesthesia, dysesthesia, and chemical neuritis. We report a rare complication, prolonged severe vertigo and ataxia, after neurolytic mandibular blockade in a patient suffering from trigeminal neuralgia. Coronoid approach was used for right sided mandibular block. After successful test injection with local anesthetic, absolute alcohol was given for neurolytic block. Immediately after alcohol injection, patient developed nausea and vomiting along with severe vertigo, ataxia and hypertension. Neurological evaluation was normal except for the presence of vertigo and ataxia. Computerised tomography scan brain was also normal. Patient was admitted for observation and symptomatic treatment was given. Vertigo and ataxia gradually improved over 24 hours.

We report a case of trigeminal neuralgia caused by persistent trigeminal artery (PTA) associated with asymptomatic left temporal cavernoma. Our patient presented unstable blood hypertension and the pain of typical trigeminal neuralgia over the second and third divisions of the nerve in the right side of the face. The attacks were often precipitated during physical exertion. MRI and Angio-MRI revealed the persistent carotid basilar anastomosis and occasionally left parietal cavernoma. After drug treatment of blood hypertension, spontaneous recovery of neuralgia was observed and we planned surgical treatment of left temporal cavernoma.

Our objective is to explore the clinical manifestations, imaging features, and therapy of trigeminal neuralgia (TN) caused by vertebrobasilar dolichoectasia (VBD). Clinical and imaging data of 11 cases with trigeminal neuralgia caused by VBD were retrospectively analyzed, and relevant literatures were reviewed. Of these 11 patients, 8 were male, and 10 suffered from hypertension. Imaging findings revealed that the vertebrobasilar arteries were pathologically enlarged and tortuous. Facial pain disappeared or was relieved after the microvascular decompression (MVD) in all 11 patients; no recrudescence was found with an average of 22-month follow-up. We concluded that TN caused by VBD, a rare clinical disease, mainly occurred in older men with a history of hypertension. CT, MRI, and MRA have great significance in the diagnosis of this disease; MVD is a preferred treatment method.

Dolichoectasia is a medical term used to describe elongated and dilated vessels that follow a tortuous and windy course with frequent loops and curves. We are presenting the natural history in images of a normal basilar artery becoming dolichoectatic, followed by the formation of an aneurysm, over a period of many years, in 60-year-old Caucasian man with a long history of secondary progressive multiple sclerosis and uncontrolled arterial hypertension, who was diagnosed with dolichoectasia of basilar artery in 2008. Although relatively stable at this point, eventually his mobility deteriorated and signs from the cranial nerves, such as trigeminal neuralgia and bilateral palsy of the VI and the VII nerves were added in the clinical picture. In 2014, both computed tomography and magnetic resonance imaging of the brain revealed the formation of an unruptured aneurysm of the basilar artery.

A 74-year-old female with trigeminal neuralgia developed hypertension after the initiation of carbamazepine therapy. The time sequence of start of the suspected drug and onset of hypertension are consistent with the diagnosis. The hypertension did not resolve with antihypertensive therapy or dose reduction of carbamazepine. Patient recovered after the carbamazepine therapy was discontinued. The positive rechallenge and positive dechallenge showed association of carbamazepine therapy with hypertension as its adverse effect. This is a rare case that we report of carbamazepine-induced hypertension and this report may act as alerting mechanism to the health care professionals especially neurologists.

Gingival overgrowth (GO) is one of the common findings in clinical practice. There could be several causes including drugs associated with the GO. Carbamazepine (CBZ) and amlodipine are the drugs which are infrequently documented as a cause in inducing the gingival hyperplasia. Certain drugs in the body fluid might limit the population of plaque bacteria and alter their metabolism that in turn induce the inflammatory mediators and also activate the genetic and biochemical factors responsible for gingival fibroblast growth. Drug-induced GO is a side effect with a multifactorial etiology that seems to orchestrate the interaction between drugs and fibroblasts in the gingiva. We describe a case of trigeminal neuralgia with hypertension treated with multiple drugs including amlodipine and CBZ. Although amlodipine is known to be infrequently associated with GO, an association of CBZ with GO is even rarer. Causality analysis on the World Health Organization Uppsala Monitoring Centre's scale indicates a probable association with offending drugs.

Hyperactive dysfunction may affect all cranial nerves in the posterior fossa. According to literature review and personal experience, hemifacial spasm was found to be associated not only with the most frequent cranial nerve syndromes, namely: trigeminal neuralgia, vago-glossopharyngeal neuralgia or VIIIth nerve disturbances manifested by vertigo, tinnitus, hearing decrease, but also with rarer syndromes like geniculate neuralgia, masticatory spasm etc. Also, a number of publications have pointed out the relatively high incidence of the coexistence of hemifacial spasm and systemic blood hypertension; both can be cured by vascular decompression of the ventrolateral aspect of the medulla and IX-Xth route entry zone (REZ) together with the facial REZ. Even more complex clinical presentations have been encountered, corresponding to disturbances in several cranial nerve nuclei. Some could be attributed to neurovascular conflicts from elongated arteries invaginated into the brainstem, and cured by microvascular decompression surgery. When confronted with such complex, and therefore misleading, syndrome, it is advised to search for vascular conflicts at the brainstem using high-resolution MRI exploration.
