Introduction: Intracranial hypertension is a picture characterized by elevated cerebrospinal fluid pressure that may cause some different complications including optic disc edema and visual accuracy alterations. Although treatment is generally pharmacological, invasive therapeutical techniques such as optic nerve sheath fenestration and lumboperitoneal shunt are sometimes required. The latter one is a technique that usually provides good results with a low complication rate, including infections, mechanical failure and overdrainage., Case Report: We report the case of a 40 year-old female patient with an idiopathic intracranial hypertension picture who required a lumboperitoneal shunt due to her progressive deterioration. After a few hours, the patient developed an intracerebral hematoma and subarachnoid hemorrhage, and some days later she developed a venous sinus thrombosis. These two complications, although described in the literature, are very unusual., Conclusions: Even though the lumboperitoneal shunt is a safe technique with good results, it is not exempt from complications. We alert about the need to take into account subarachnoid hemorrhage and venous sinus thrombosis as possible complications in the followup of these patients.

The paper aims to present the case of a progressive and unilateral cranial polyneuropathy due to perineural spread of cutaneous squamous cell carcinoma. This is a case of a 73 year old man with a history of squamous cell carcinoma in the right temporal region that was removed in 1992. In May 2000 he first presented pain and numbness in the distribution of the first branch of right trigeminal nerve and weakness of the ipsilateral frontal muscle. Later on he presented right ophthalmoplegia, and damage of lower cranial nerves, leading to dysphagia and respiratory distress. He was admitted in March 2001 for a gastrostomy for feeding, when ataxia and recurrence of the right temporal lesion ensued. After three examinations with MRI, the fourth study showed meningeal carcinomatous and a metastatic lesion in the brainstem. Histopathologic examination demonstrated dermal and perineural invasion by squamous cell carcinoma. The necropsy also showed meningeal, perineural and endoneural infiltration of atypical epidermal cells and a pons mass composed of the same cells. We conclude that the perineural spread of the cutaneous carcinoma is an exceptional cause of cranial neuropathy, however it must be ruled out in patients with progressive and unilateral cranial neuropathy. In these cases, when no radiological abnormalities are noted, a biopsy may be performed on the peripheral branches of the cranial nerve to confirm the diagnosis.

The presence of intracranial hemorrhage with a fluid-blood level in patients receiving anticoagulant medication or with coagulopathy is an infrequent but well-documented complication. We reported a patient with a fluid-blood level with normal haemostasis. A 62-year-old-man was admitted with a left putaminal hemorrhage containing a fluid-blood level, but without abnormal haemostasis. Five months later the patient returned to the hospital because of a transient ischemic attack. A cranial CT demonstrated a hypodensity in the left putamen nucleus and corona radiata. Electrocardiogram revealed atrial fibrillation and a cardiac ultrasonographic examination showed mitral annulus calcification and left atrial enlargement. The finding of intracranial fluid-blood level has been seen in patients with arteriovenous malformations, primary and metastatic neoplasm, radiation-induced necroses, cerebral amyloid angiopathy, intrainfarct hematoma and without any identified aetiology. We suggest that in our patient this disorder was due to a intrainfarct hematoma.
