RESUMO

An 85-year-old male patient was referred to our hospital for further examination of a liver tumor. Imaging examination revealed a 90-mm tumor in segment 4/8 and 30-mm tumor in segment 6 of the liver. Histopathological examination revealed that the tumor in segment 4/8 was cholangiolocellular carcinoma (CLC) and the tumor in segment 6 was hepatocellular carcinoma (HCC). This case shows that although the frequency of CLC is very low, recent studies have indicated the novel knowledge of CLC. Herein, we report a surgical case of CLC and HCC in the background of resolved hepatitis B virus infection.

RESUMO

Craniopharyngiomas are histopathologically classified as adamantinomatous type (AD) and squamous-papillary type (SP). However coexistence of a mixed type seen on histopathologic specimens has not been reported. In this report, a patient diagnosed with mixed type craniopharyngioma is presented and the etiology and pathologic features are discussed.

RESUMO

An 80-year-old male presented with a chronic encapsulated intracerebral hematoma (CEIH) with surrounding edema under the right frontal lobe manifesting as slow exacerbation of disturbance of orientation and gait. He had a history of cerebral infarction with an asymptomatic cavernous angioma in the right frontal lobe. The CEIH was diagnosed as bleeding from the cavernous angioma, and surgical removal was performed. The hematoma was chronic and covered by a thick capsule. In addition, mass tissue covered with the organized hematoma was found near the capsule, which was excised and found to be a cavernous angioma. CEIH is a special type of intracerebral hemorrhage, and bleeding from a cavernous angioma is occasionally seen. CEIH should be considered in the case of a hemorrhagic intracranial lesion with a chronic, progressive course with capsule formation and edema around the lesion. The source of bleeding is unknown in about half of the reported cases, and occult vascular malformation may be involved, necessitating care in diagnosis.

RESUMO

BACKGROUND: Craniopharyngioma has two subtypes: adamantinomatous and squamous-papillary. Squamous-papillary craniopharyngioma may develop from remnants of the craniopharyngeal duct, anterior pituitary cells with squamous metaplasia, suprasellar epidermoid cyst, or Rathke cleft cyst. AIM: While ciliated craniopharyngioma is considered to represent a transitional stage between Rathke cleft cyst and squamous-papillary craniopharyngioma, ciliated craniopharyngioma following Rathke cleft cyst at the same site has not previously been described. RESULTS: We report a case of ciliated craniopharyngioma developing from Rathke cleft cyst. CONCLUSION: The clinical course for this case is discussed together with a review of the pathological literature for ciliated craniopharyngioma.

RESUMO

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.

RESUMO

A 28-year-old woman presented with a rare case of endodermal cyst located ventral to the lower brain stem manifesting as recurrent aseptic meningitis. Computed tomography and magnetic resonance imaging demonstrated a cystic mass located ventral to the lower brain stem and extending from the prepontine to the upper cervical (C-2) cistern. The lesion was totally removed through a retrosigmoid craniotomy and C1-2 hemilaminectomy. Histological and immunohistochemical examination showed the cyst was derived from the endoderm. The histological diagnosis was endodermal cyst. Early diagnosis and surgical removal are important for patients with these cysts.
