Isolated fourth ventricle is an untoward but interesting complication caused by the shunt procedure, which has been recognized since the introduction of CT scanning. Auditory brain stem evoked potentials (BAEPs) were recorded in a patient with isolated fourth ventricle for assessment of brain stem function. Case 1. A 9-year-old boy. He had undergone repair of the lumbosacral meningocele at birth, followed by shunting procedures, including repeated shunt revision, for hydrocephalus which subsequently developed. CT scanning on admission revealed typical findings of isolated fourth ventricle, while neurological examination disclosed no abnormalities. BAEPs on admission revealed normal waves both in amplitude and latency. This patient has been doing well without further shunting procedures. Case 2. A 17-year-old male was admitted with complaints of headache, diplopia, nystagmus and ataxic gait. He had a history of operation for radical removal of cerebellar astrocytoma and lateral ventriculo-peritoneal shunt at 9 years of age. CT scanning on admission revealed a typical isolated fourth ventricle, and fourth ventricle-peritoneal shunt was performed. Postoperative serial BAEPs revealed gradual improvement of brain-stem function. Clinically he has been symptom-free thereafter except for slight nystagmus. Case 3. A 2-year-old female suffering from hydrocephalus developed after neonatal intraventricular hemorrhage and ventriculitis. After repeated revision of a lateral ventriculo-peritoneal shunt, she was admitted in semicoma with vomiting and opisthotonic posture. CT study revealed an isolated fourth ventricle and preoperative BAEPs showed marked abnormalities. Although fourth ventricle-peritoneal shunt was performed, no remarkable change in BAEPs was obtained, and neurological deficit of considerable degree persisted.(ABSTRACT TRUNCATED AT 250 WORDS)

We report a 43-year-old woman who suffered from Listeria monocytogenes meningitis. She was admitted to our hospital because of headache, nausea, vomiting, and fever. On admission she had no abnormal neurological signs except for severe nuchal stiffness. Cerebrospinal fluid (CSF) examination on the day of admission revealed pleocytosis and increased total protein level. The CSF culture demonstrated Listeria monocytogenes. Because ampicillin therapy was not effective, erythromycin (8 g/day) was added. After 12 hours of erythromycin therapy, the patient complained of moderate hearing difficulty. Erythromycin was then stopped on the next day. Her hearing improved and became normal within 48 hours after discontinuation of erythromycin. Contrast MRI of the brain revealed enhancement of the ependyma of the lateral ventricle, suggesting the presence of ventriculitis. By parenteral administration of ampicillin and cephazolin, clinical symptoms improved quickly, and abnormal CSF and MRI findings were normalized. Listeria meningitis accompanied with ventriculitis has been reported in neonates and infants, but not in adults. In addition, this is the first case with erythromycin-induced hearing loss in the Japanese literature. Hearing should be regularly examined in patients who are treated with high-dose erythromycin (> or = 4 g/day), and the drug should be immediately discontinued when the patient develops hearing loss.

In 1989-1998 ENT specialists of the Tashkent Institute of Postgraduate Medical Education treated 109 patients with otogenic intracranial complications. 13 (11.9%) of them had cerebellar abscess. Clinical symptoms of the abscesses were obscure or absent. Head ache was the leading symptom. Other hypertensive symptoms presented with nausea, (n = 2), vomiting (n = 5), bradycardia (n = 7). Changes on the fundus of the eye were not registered in 6 patients. Defective coordination of movements, scanning speech were observed in 11 and 3 patients, respectively. Large-swinging, mixed horizontal nystagmus was truncal, in 11 patients it was directed to the side of the abscess, in 2 patients--in both directions. Symptoms of the secondary meningitis arose in 12 patients. The patients underwent surgical cleaning of the middle ear and opening cerebellar abscess under drug therapy. One patient died of purulent ventriculitis (lethality 7.6%). It is inferred that cerebellar abscesses often run with mild symptoms. This creates diagnostic difficulties.

We present a case with brain abscess associated with entrapment of the lateral ventricle appearing more like remarkable brain edema in the temporo-occipital lobe than ventricular dilatation. A 72-year-old man suffering from headache and vomiting visited our clinic. CT and MRI showed brain abscess in the right parieto-occipital lobe, associated with ventriculitis. Lumbar puncture also revealed purulent meningitis. Both symptoms and CSF findings improved after administration of antibiotics. The improved condition continued for two months after admission, but disturbed consciousness and left hemiparesis than appeared. MRI and CT showed entrapment of the lateral ventricle and brain edema of the right temporo-occipital region without ventricular dilatation. Because brain edema was thought to be caused by transudate of the CSF through the ventricular wall, lobectomy of the right temporal lobe and opening of the temporal horn were carried out. Although left hemiparesis and disturbed consciousness and brain edema disappeared after the operation, subdural effusion appeared. Using a subdural-peritoneal shunt, the subdural effusion was prevented and disappeared. In this case, we thought Hounsfield Unit (HU) of the brain edema caused by transudate of CSF through the ventricular wall (12.6) was markedly lower than that of so-called vasogenic edema (25.1) due to active inflammation. Measurement of the HU seemed to be a useful means to differentiate the types of brain edema in this situation from that of vasogenic edema caused by brain abscess, and thus a means for selection of the appropriate treatment.

Osteomas of the cranial sinuses are rare, benign bony tumors that can be complicated by the formation of an intracranial pneumatocele. If not treated promptly, a pneumatocele can lead to abscess formation, meningitis, or ventriculitis. In the present case, an intracerebral pneumatocele was formed when an 18 cm(3) osteoma breached the posterior wall of the frontal sinus creating a one-way valve through which air could enter the intracranial cavity. The patient presented after forceful sneezing with nonspecific symptoms of headache, nausea, and vomiting. CT demonstrated a frontal collection of loculated air with mass effect within the left cerebral hemisphere. A partly mineralized mass occupied the left superior nasal ethmoid sinus and left frontal sinus. Of interest pathologically in this case, the tumor had a substantial osteoblastoma-like component. Surgical repair involved frontal craniotomy to remove the osteoma and debride frontal sinus mucosa, plugging the frontal nasal ducts and sinus with fat and bone wax, and dural restoration using an underwater closed drainage system to vent intracranial air and stabilize the patient.

Acute necrosis of the ventriculus is a very uncommon lesion in birds. We describe a fatal case of acute necrotising ventriculitis caused by Rhizopus microsporus var. chinensis in a mature female eclectus parrot (Eclectus roratus). The bird presented acutely dull and lethargic, was vomiting and had bright green droppings, suggestive of acute heavy metal poisoning. It was treated with fluids and chelation therapy, but died within 12 h. Necropsy, cytology, histopathology and culture results demonstrated fungal invasion of the ventriculus associated with transmural necrosis, haemorrhage, acute inflammation and abundant R. microsporus var. chinensis and lesser numbers of Candida krusei.

To describe a fatal case of invasive Aspergillus flavus sinusitis in a 43-year old female with sickle cell disease (SCD) complicated by intracerebral aspergilloma and invasive Salmonella infection. Cerebral aspergilloma carries a very high mortality rate. The patient developed post-craniotomy intracerebral hemorrhage at the site of biopsy, Salmonella species sepsis and ventriculitis. She presented with a 2-month history of headache, dizziness, personality and behavioral changes, and vomiting. Initial clinical evaluation raised the suspicion of brain tumor. Brain magnetic resonance imaging revealed a left frontal, thick-walled ring-enhancing lesion with extensive surrounding edema suggestive of a neoplastic lesion, or a contiguous inflammatory or infectious process from the skull base. Despite early diagnosis and appropriate antifungal and surgical management, she eventually died from severe infection and respiratory arrest. In conclusion, invasive aspergillosis should be included in the differential diagnosis of SCD patients with central nervous system (CNS) lesions.

The spleen plays an important role in the body's immune defense against invasive infections, particularly those caused by encapsulated bacteria. Encapsulated bacterial infection in asplenic patients is a medical emergency called overwhelming postsplenectomy infection (OPSI) and has a mortality rate of 50-70%. Here, we report the case of a 51-year-old Asian man who complained of emesis and diarrhea as primary symptoms. He rapidly progressed to coma and was eventually diagnosed with OPSI (pyogenic ventriculitis/spondylitis) caused by non-vaccine pneumococcal serotype 23A. Aggressive management, including empiric antibiotic therapy, a staircase approach for intracranial pressure-targeted therapy and laminectomy/laminoplasty, resulted in a good recovery. Our report highlights that non-vaccine pneumococcal serotypes can cause disease in vaccinated patients.
