✓The authors report a case of inflammatory pseudotumor that developed in the choroid plexus of the lateral ventricle. The patient was a 73-year-old man who had undergone surgery for rectal cancer at another hospital 5 years earlier. He was referred to the authors' department, with his chief symptoms consisting of disorientation, right hemiparesis, and gait disorder that had gradually developed during the preceding month. On computed tomography and magnetic resonance imaging, a well-demarcated and homogeneously contrasted tumorous lesion was noted in the region from the trigone to the medial wall of the inferior horn of the left lateral ventricle. Expansion of the inferior horn was also evident. Intraoperative findings showed that the tumor originated from the choroid plexus of the lateral ventricle, and the histopathological diagnosis was inflammatory pseudotumor. There are only 4 previously reported cases of inflammatory pseudotumor that developed in the choroid plexus; the authors review the literature and discuss the clinicopathological characteristics of the condition.

✓ Except for villous hypertrophy of the choroid plexus that may not be true tumors, multiple choroid plexus papillomas are extremely rare. The authors report a case involving multiple choroid plexus papillomas that were distinct from villous hypertrophy. These lesions were localized, one in the atrium of the right lateral ventricle and the other in the inferior horn of the left lateral ventricle. A review of the literature revealed that this case represented the first reported case of true multiple choroid plexus papillomas documented by findings on magnetic resonance imaging.

BackgroundLate paraphrenia is recognised as a heterogeneous disorder. This is reflected by the division of such patients into schizophrenia and delusional disorder in ICD-10. Earlier imaging studies have suggested that major structural abnormalities may be associated with the onset of psychosis in later life.MethodFifty late paraphrenics and 35 age-matched healthy controls underwent structural magnetic resonance imaging of the whole brain in the coronal plane. Measurements were made of intracranial and brain volumes and the volumes of the intracerebral and extracerebral cerebrospinal fluid spaces.ResultsNo differences in intracranial, brain or extracerebral cerebrospinal fluid volumes between patients and controls were found. Late paraphrenic patients had greater lateral and third ventricle volumes than controls and the left lateral ventricle was larger than the right. When the patients were divided into appropriate ICD-10 diagnoses: paranoid schizophrenia (n= 31) and delusional disorder (n= 16), lateral ventricle volumes in the delusional disorder patients were much greater than those of the schizophrenics and almost twice those of controls.ConclusionsStructural brain differences underly diagnostic heterogeneity within late paraphrenia. The brains of late onset schizophrenics are only subtly different from those of healthy elderly individuals.

AbstractThe dentate nucleus is the largest cerebellar nucleus, and it controls cognition and voluntary movement. It is found in each cerebellar hemisphere medially and posterolateral to the lateral ventricle. Pathologies of the dentate nucleus can be detected using computed tomography and magnetic resonance imaging of the brain. Here, we present a case series of seven different dentate nucleus diseases and their neuroimaging findings recovered from archives of our institution.

Primary submandibular gland oncocytic carcinoma is a rare pathology, with only 10 cases being reported to date. We encountered a case of primary submandibular gland oncocytic carcinoma and report it herein. The patient was a 69-year-old man who came to our hospital with right submandibular cancer as the main complaint. Based on the results of computed tomography and magnetic resonance imaging, submandibular gland tumor was diagnosed. Preoperative cytodiagnosis suggested class III oncocytic carcinoma. Resection of the right submandibular tumor was performed along with right neck dissection. Postoperative histopathological diagnosis was oncocytic carcinoma. As of 3 years following surgery, no recurrence has been identified.

Racemose and intraventricular neurocysticercosis are uncommon types of neurocysticercosis, resulting in a multiloculated, grape-like cluster appearance in the cerebrospinal fluid (CSF) spaces. A male patient presented with symptoms of raised intracranial pressure and demonstrated racemose neurocysticercosis at an atypical location involving the region of the crus of the fornix at the level of the body of lateral ventricles on magnetic resonance imaging. Associated intraventricular neurocysticercosis was seen in the atrium of the left lateral ventricle and fourth ventricle.
