The Tolosa-Hunt syndrome(THS) consists of a painful ophthalmoplegia related to a granulomatous inflammatory process in the cavernous sinus, which may be documented by cerebral magnetic resonance imaging with gadolinium enhancement. Generally, it has been reported that 2 weeks steroid therapy relieves the symptoms(periorbital pain, ophthalmoplegia) of THS. In this case, there had been no improvement of symptoms by western medical treatments(steroid & analgesics). but, the symptoms were resolved clearly by acupuncture therapy during 6 weeks(5 times/week). If more clinical trials like this are proved to be effective in THS, we can expect that acupuncture will be another therapeutical modality in THS.

Idiopathic hypertrophic cranial pachymeningitis (ICHP) is diffuse inflammatory process of the dura mater. ICHP can produce similar presentation with Tolosa-Hunt syndrome (THS) if it involves cavernous sinus. A-29-year old male with persistent headache and no definite neurologic dysfunction was noted. Two weeks later, he complained of ophthalmoplegia, and his symptoms were thought to be manifestations of THS. Brain magnetic resonance images revealed diffuse thickened, enhanced pachymeninges in left tentorium. The patient was diagnosed with IHCP. We report a IHCP patient who showed very similar presentation as THS.

Mortality associated with maxillofacial infection is relatively low due to the development of antibiotics, and improved oral care. However, inappropriate treatment, delayed treatment, old age, underlying systemic disease, and drug-resistant micro-organisms can potentially result in life threatening situations such as cavernous sinus thrombosis, mediastinitis, and sepsis. Sepsis is the most dangerous state with high mortality, ranging from 20~60%. The treatment of sepsis involves properly monitoring vital functions, fluid resuscitation, surgical drainage, and empirical use of high doses of antibiotics until culture results are available. Ventilatory support maybe be required as well. We encountered a 64-year-old patient who died from sepsis that developed as the result of an odontogenic infection. The initial diagnosis was right temporal, infraorbital, buccal, pterygomandibular space abscess. Despite surgical and medical supportive care, the condition progressed to sepsis and after four days the patient died due to multiple organ failure.

Intracranial chloroma may occur in leukemia, although they are rare. A 23-year-old female complained diplopia. Brain magnetic resonance MR imaging showed tumors in the both cavernous sinus, both tentorial and anterior falx. Gamma-Knife radiosurgery was performed with maximal dose; 20Gy, marginal dose; 10Gy. Peripheral blood smear revealed leukemia, and bone marrow aspiration biopsy showed acute lymphocytic leukemia. Two weeks later, MR image for the stereotactic biopsy noticed markedly decreased tumor size. Biopsy result was lymphocytic leukemia. She received conventional radiation therapy, chemotherapy, and bone marrow transplantation. Brain involvement by acute lymphocytic leukemia is very rare. Even though chloroma are sensitive to radiation therapy, prognosis is poor because of the gravity of the underlying disease and association with impending blast transformation. The authors reports a intracranial chloroma by acute lymphocytic leukemia.

Hemangiopericytoma [HPC] is a rare tumor with uncommon location in the central nervous system. We report a rare case of sellar and suprasellar HPC mimicking pituitary adenoma in a patient initially seen with the symptoms of bitemporal hemianopsia, headache, and panhypopituitarism. Magnetic resonance imaging of the brain revealed a contrast-enhancing soft tissue mass arising from the pituitary fossa, with apparent compression of the chiasm and involving the cavernous sinus. Subtotal resection of the tumor was achieved via a pterional approach. Histopathological examination identified the tumor as a HPC. Nine years later, the tumor recurred. To our knowledge, this is the first reported case of sellar and suprasellar HPC in Korea.

The Tolosa-Hunt syndrome is a symptom complex with unilateral painful ophthalmoplegia associated with retro-orbital pain, proptosis and Ⅲ, Ⅳ, Ⅴ-1, Ⅵ cranial nerves palsy due to nonspecific granulomatous inflammation in the superior orbital fissure or cavernous sinus. We experienced a 50 years old female patient with Tolosa-Hunt syndrome who had several clinical signs and symptoms such as ocular pain, headache, sensory loss of face, diplopia, and visual disturbance. In the point of Differentiation of Syndrome(辨證). this subject was diagnosed as Deficiency of yin in liver and kidney(肝腎陰虛), and was administrated with Yangyeummyungmoktang-Gamibang. After treatment of acupuncture and herbal medicine above symptoms were improved.

Tumors that metastasize to the pituitary gland are unusual and metastasis of neuroendocrine neoplasm to the sellar region is extremely rare. We report a 59-year-old man with pituitary metastasis from pulmonary carcinoid tumor who presented with left progressive deterioration of visual field. Sellar dynamic magnetic resonance imaging revealed an enhancing sellar mass invading the left cavernous sinus. We report this unusual case with a review of the relevant literature.

The abducens nerve (AN; cranial nerve VI) exits the brainstem at the inferior pontine sulcus, pierces the dura of the posterior cranial fossa, passes through the cavernous sinus in close contact to the internal carotid artery (ICA) and traverses the superior orbital fissure to reach the orbit to innervate the lateral rectus muscle. At its exit from the brainstem, the AN includes only axons from lower motor neurons in the abducens nucleus. However, as the AN crosses the ICA it receives a number of branches from the internal carotid sympathetic plexus. The arrangement, neurochemical profile and function of these sympathetic axons running along the AN remain unresolved. Herein, we use gross dissection and microscopic study of hematoxylin and eosin-stained sections and sections with tyrosine hydroxylase immunolabeling. Our results suggest the AN receives multiple bundles of unmyelinated axons that use norepinephrine as a neurotransmitter consistent with postganglionic sympathetic axons.

Purpose To compare the sensitivities of T2-weighted image (T2WI) and susceptibility-weighted imaging (SWI) in detecting cerebral arteriovenous fistula (AVF), cerebral arteriovenous malformation (AVM), and carotid-cavernous sinus fistula (CCF), and to qualitatively evaluate single-echo SWI (s-SWI) and multi-echo SWI (m-SWI) in characterizing vascular lesions. Materials and Methods From January 2016 to December 2021, cerebral angiography-proven lesions were recruited. The sensitivities of T2WI and SWI in detecting vascular lesions were compared using McNemar's test. Qualitative evaluations of s-SWI and m-SWI were categorized to be of poor, average, or good quality and compared using Fisher's exact test. Results A total of 24 patients (mean age: 61 years, 12 female, and 12 male) were enrolled. Twenty patients underwent s-SWI or m-SWI, and four patients underwent both. AVF, AVM, and CCF were diagnosed in 10, 11, and 3 patients, respectively. SWI demonstrated higher sensitivity compared to that of T2WI (82.1% vs. 53.6%, p = 0.013). m-SWI showed better image quality compared to that of s-SWI (good quality, 83.3% vs. 25.0%, p = 0.009). Conclusion SWI demonstrated a higher sensitivity for detecting cerebral arteriovenous shunts compared to that of T2WI. m-SWI exhibited better image quality compared to that of s-SWI in characterizing vascular lesions.

Central venous stenosis is a relatively common complication in hemodialysis patients; however, jugular venous reflux (JVR) and increased intracranial pressure are rare, and associated progressive visual disturbance was reported in only a few cases. Here, we report a case of JVR with visual disturbance and increased intracranial pressure. Notably, the MRI was accompanied by a dilatation of the superior ophthalmic vein, which was mistaken for a cavernous sinus dural arteriovenous fistula (CSdAVF). The patient had JVR on time-of-flight MR angiography (TOF-MRA) and severe stenosis of the left brachiocephalic vein on conventional angiography. After balloon angioplasty for central venous stenosis, he was discharged after improvement of his visual disturbance. Although JVR due to central venous stenosis and CSdAVF might show similar symptoms, treatment plans are different. Therefore, it is important to distinguish radiologically based on a thorough review of MRI and TOF-MRA and confirm the central venous stenosis on cerebral angiography for the accurate diagnosis.
