We report on a patient who presented with cranial nerve VI bilateral paresis, absence of pharyngeal reflex, dysarthria, right tongue deviation, and right facial paralysis. Imaging studies showed an expansive process in the cranial base with clivus and petrous apex osteolysis. A biopsy confirmed the presence of clear cell adenocarcinoma and suspicion of renal tumor metastases. Abdominal imaging ...

This report documents a 47-year-old male who developed acute deficits of the IX, X, XI, XII cranial nerves and Horner's symptoms, consistent with Villaret's syndrome. Neuroimaging studies demonstrated an osteolytic lesion in the skull base involving the clivus and jugular foramen. The patient recovered after the antibiotic treatment for proteus mirabilis infection. We suggest that Villaret's sy...

Dural arteriovenous fistulas (dAVFs) may present in a variety of ways, including as carotid-cavernous sinus fistulas. The ophthalmologic sequelae of carotid-cavernous sinus fistulas are known and recognizable, but less commonly seen is the rare clival fistula. Clival dAVFs may have a variety of potential anatomical configurations but are defined by the involvement of the venous plexus just over...

Abstract Background Langerhans cell histiocytosis (LCH) is an abnormal polyclonal proliferation of cells that affect different parts the body. Temporal bone involvement quite common among involved sites. The etiology unknown. Diagnosis based on symptoms, imaging, and histopathology. Especially LCH in temporal confused with acute or subacute otitis media. There are many treatment options LCH. Ca...

CASE HISTORY A 44-year-old housewife presented in December 1966 with a two-month history of neck pain accentuated by coughing and sneezing. The neck was short and movements were painful, but there were no other abnormal signs. X-ray pictures of the cervical spine and chest were normal. The haemoglobin was 10-8 g./100 ml.; white cell count 6,000/cu. mm.; E.S.R. 44 mm. in the 1st hour; M.C.H.C. 3...

Chordomas are rare tumours which arise from remnants of the primitive notochord. They occur primarily in the sacrum, clivus and cervical regions. We report a case of retroclival chordoma which presented as an extradural haemorrhage following minor trauma. The underlying tumour was not apparent on imaging performed immediately following the event, and chordoma presenting in this manner has not p...

Midfacial degloving is an extended sublabial rhinotomy, which permits good bilateral access to the nasal and paranasal cavities, the base of the skull, and the clivus. The incisions leave no visible scars. The access is suitable for large benign tumours (such as nasopharyngeal fibromas or inverted papillomas), but can also be used for malignant tumours. It can be enlarged by supplementary incis...

Global climate change is heavily affected by an increase in CO2. As one of several efforts to cope with this, research on poplar, a representative, fast growing, and model organism plants, actively underway. The effects elevated atmospheric CO2 the metabolism, growth, transcriptome poplar were investigated predict productivity environment where concentrations are increasing. Poplar trees grown ...
