Intracranial infections, especially subdural empyema, due to salmonella are rare. Subdural empyema caused by Salmonella paratyphi A has been documented only once earlier in the literature. Hence, we report a case of subdural empyema and osteomyelitis of cranial vault due to S. paratyphi A. A 42- year-old male presented with headache and purulent discharge from right parietal burr hole wound site. Patient gave a history of head injury two years ago. He underwent burr hole evacuation of chronic subdural haematoma, excision of outer membrane and right parietal craniectomy. The cultures grew S. paratyphi A. Recovery was uneventful following surgical intervention and antibiotic therapy.

A 42-year-old black African patient was admitted in the emergency department with severe headache, dizziness, and visual problems. He had been treated for hypertension diagnosed eight months ago after a similar episode. He was taking atenolol 100 mg /day, amlodipine 10 mg/day, and a combination of lisinopril 20 mg/hydrochlorothiazide 12.5 mg daily but experienced several hypertension peaks and hypotension. He adhered to treatment and was neither using traditional herbal medication nor illicit drugs. He did not smoke, but used to drink 1-2 glasses of wine after dinner. At admission, his blood pressure was 235/145 mm of Hg. His body mass index was 25.5 kg/m(2) and the waist/hip ratio was 0.9. Physical examination was unremarkable. Fundoscopic examination revealed hypertensive retinopathy. Biochemical and imaging explorations were compatible with diagnosis of pseudopheochromocytoma. Evolution was favourable after treatment with alpha-1 and beta-blokers.

Middle cerebral artery (MCA) fusiform aneurysms often have an unfavorable geometry that may limit surgical or endovascular treatment. Herein, we present a case of a fusiform aneurysm of the proximal MCA, which was successfully treated using stent-assisted coil embolization. A 42-year-old man presented with repeated headache and syncope. Five years earlier, a right MCA aneurysm had been treated by aneurismal wrapping. Magnetic resonance images (MRI) revealed a partially-thrombosed proximal MCA aneurysm at the right perisylvian region. Digital subtraction angiography (DSA) revealed a multilobulated fusiform-shaped aneurysm. The patient underwent stent-assisted coil embolization under general anesthesia and symptoms resolved postoperatively. A three-month follow-up angiography revealed no recanalization of the aneurysm and indicated tolerable blood flow through the right MCA, as compared to the preoperative angiography. We suggest that in selected patients, stent-assisted coil embolization of proximal MCA fusiform aneurysms can be an effective treatment modality.

Several anatomical studies indicate that the intracranial pachimeninges consist of two dural layers joined together, which divide while bordering the venous sinuses, therefore located in an interdural space. We present here an uncommon case of haematoma due to rupture of an infraclinoidal internal carotid artery aneurysm. The dome of the aneurysm leaned against the posterior wall of the cavernous sinus and, following laceration, pierced the inner dural layer and caused its detachment from the periosteal layer, thus determining a truly interdural haematoma which progressively involved the whole posterior fossa. A 42-year-old female was admitted to our institution with a recent history of thunderclap headache and right ophthalmoparesis. Two cerebral computerised scan tomographies performed elsewhere tested negative for subarachnoid haemorrhage. A cerebral magnetic resonance imaging (MRI) showed a thin collection of blood adjacent to the clivus and all along the wall of the posterior fossa and foramen magnum. A right infraclinoid internal carotid artery aneurysm was also diagnosed, subsequently better highlighted on angiography. The patient underwent surgery with aneurysm clipping. Post-operative course was uneventful, and control angiography showed complete exclusion of the aneurysm from blood circulation. The patient was discharged 5 days later. At 3 months follow-up ophthalmoplegia had disappeared, and the patient had fully recovered. The possibility of a truly interdural location, particularly in cases of non-traumatic parasellar or clival haematomas, must be included in the differential diagnosis of posterior fossa extra-axial haemorrhages. MRI is the test of choice for diagnostic purposes.

Trans-nasal sphenoid sinus foreign body is a rare condition. We report a case of trans-nasal gun bullet within the sphenoid sinus with breach of the floor of the sella turcica. A 42-year-old soldier presented a few weeks after a gun battle with a history of headache. The skull x-ray demonstrated a foreign body in the region of sphenoid sinus and sella. Multidetector-row CT with multiplanar reformats demonstrated a bullet within the sphenoid sinus with its tip penetrating into the sella turcica. A few days later the patient coughed up the bullet as it came out spontaneously without any intervention. This is perhaps the unique occurrence of such a foreign body.

Chronic daily headache (CDH) among nasopharyngeal carcinoma (NPC) patients is a multidisciplinary challenge. Although imaging studies are recommended to identify skull-base invasion, intracranial metastasis or skull-base osteoradionecrosis, a headache diary is also a practical approach. A 42-year-old woman had been bothered with CDH since she was diagnosed with T3N1M0 stage III NPC 2 years earlier. Although the imaging studies did not show any abnormality, the attending doctor informed her that there remained the possibility of an intracranial or skull-base lesion. She was regularly taking painkillers. Eventually, when her headache diary was examined, the diagnosis of chronic migraine superimposed on medication overuse headache was made according to the ICHD-IIR. The CDH abated after 1 week of outpatient detoxification. The following half year was uneventful. In reporting this case, we suggest that it would be of interest to a number of disciplines including otorhinolaryngologists, oncologists and radio-oncologists. By avoiding medication overuse in similar patients, we hope to improve the quality of life of these individuals.

A 42-year-old male patient presented with an anterior cerebral artery (ACA) dissection manifesting as sudden onset of severe headache. Initial computed tomography revealed faint subarachnoid hemorrhage in the frontal region. Initial angiography showed tapering stenosis at the A(2) segment of right ACA. The patient was admitted to our hospital and treated conservatively. Magnetic resonance (MR) imaging and angiography did not detect intramural hematoma, intimal flap, or double lumen at the stenotic right A(2) segment. The ACA dissection was difficult to confirm based on the findings on day 0. ACA dissection was confirmed by improvement of the right ACA stenosis on follow-up angiography on day 14. On the other hand, MR cisternography revealed a fusiform dilatation of the vascular outer contour at the right A(2) on day 0, which had resolved on day 14. Cerebral angiography and MR cisternography similarly suggested asymptomatic contralateral (left) A(2) dissection on day 14. Fusiform dilatation of the vascular outer contour at the affected segment on MR cisternography may be indicative of arterial dissection in the acute phase.

A 42-year-old woman had suffered from headaches since April 2009. Computed tomography revealed a tumor with marked calcification in the left frontal lobe adjacent to the left anterior horn of the lateral ventricle. T1-weighted gadolinium-enhanced magnetic resonance imaging showed a well-enhanced tumor at the lesion. Dynamic methionine positron emission tomography showed no delayed methionine attenuation. Initial preoperative diagnosis was extraventricular neurocytoma (EVN). However, oligodendroglioma was determined upon a second diagnosis. The patient underwent total tumor removal. Hematoxylin and eosin staining showed the characteristic fried egg-like cells, round nuclei, and immunohistochemically, the tumor cells were positive for glial fibrillary acidic protein, synaptophysin, neuronal nuclear antigen, microtubule-associated protein 2 and Olig2. The MIB-1 labeling index was 20%, which suggested malignancy. Although these findings demonstrated that the tumor had glioneuronal character, it was difficult to differentiate between EVN and oligodendroglioma. There have been reports that Olig2 immunohistochemistry is generally positive in cases of oligodendroglioma, but not in cases of neurocytoma. We completed the diagnosis as oligodendroglioma. Subsequent electron microscopy results presented oligodendroglial but not neuronal characteristics. We concluded that Olig2 is useful in the differential diagnosis of oligodendrogliomas and EVNs.

A 42-year-old immunocompetent man presented with subacute onset unilateral headache and associated lower cranial nerve palsies. Cranial magnetic resonance imaging showed enhancing thickened tentorium cerebelli and subtentorial dura mater. Cerebrospinal fluid examination revealed lymphocytic pleocytosis and positive polymerase chain reaction assay of Aspergillus DNA. While on voriconazole treatment a progressive increase was noted in subtentorial pachymeningeal hypertrophy, which was excised because of critical compression of the medulla. The excision material showed extensive fibrosis, cellular infiltrates and no organisms. With combination therapy with anti-fungal agents and corticosteroids, pachymeningitis showed regression. We hypothesised that intact immune status and less burden of Aspergillus infection in this patient may have resulted in a chronic progressive hypertrophic pachymeningitis.

Here, we demonstrate a first case of tick-borne encephalitis (TBE) associated with an isolated reversible splenial corpus callosum lesion (IRSL) and highlight the wide range of different clinical entities in which such alterations have been observed. A 42-year-old man showed fever, cephalgia and mild disturbance of coordination and gait. Diagnosis was ascertained by slight CSF-pleiocytosis and positive TBE-IgG as well as by positive intrathekal specific antibody index on follow-up. MRI demonstrated a single ovoid hyperintensity in T2 and DWI with reduction in ADC in the splenium of corpus callosum which was abrogated in follow-up after 6 weeks. Most entities of IRSL presented with excellent prognosis, including our novel case of TBE. We discuss different possible pathomechanisms and the so far unexplained propensity of the splenium for such alterations. Clinicians should be familiar with this phenomenon to avoid unnecessary diagnostic or therapeutic efforts.
