Herpes simplex virus encephalitis complicated by intracerebral hematoma
Herpes simplex virus (HSV) encephalitis complicated by cerebral
hematoma is extremely rare. We report a 54-year-old man with hepes
simplex encephalitis complicated by intracerebral hematoma and review
the literature and describe the characteristics of HSV encephalitis
complicated by intracerebral hematom
Chronic encapsulated intracerebral hematoma formation after radiosurgery for cerebral arteriovenous malformation
We report a rare case of chronic encapsulated intracerebral hematoma
(CEIH) after radiosurgery for a cerebral arteriovenous malformation
(AVM). A 49-year-old male underwent transarterial embolization and
surgical excision of a cerebral AVM presenting with cerebral hemorrhage
in the left temporal lobe. Stereotactic radiosurgery (SRS) was done
after 12 months. Magnetic resonance imaging (MRI) 14 months after SRS
showed a small-enhancing lesion close to the left lateral ventricle and
marked white matter edema. At that time a diagnosis of
radiation-induced necrosis was made and steroids administered. At 43
months after SRS, MRI showed a small-enhancing mass close to the
lateral ventricle with a hematoma cavity. Surgical excision was
performed and histological examination revealed that the capsule
consisted of an outer collagenous layer and an inner granulated layer
with deposits of hemosiderin, which was compatible with CEIH. CEIH
should be considered after SRS for AVM
Malignant transformation of an intracranial germinoma into a choriocarcinoma
The recurrence or metastasis of intracranial pure germinomas as germ cell tumours of different histological types has rarely been reported. The present report concerns the first case in the literature of intracranial recurrence of a germinoma transformed into a choriocarcinoma. A 17-year-old man presented with a 1 month history of headache. MRI revealed a homogeneously enhanced mass within the pineal and suprasellar regions. The tumour was resected, and histological examination identified it as a pure germinoma. After resection, the patient underwent chemotherapy and radiotherapy and the mass disappeared. At 5 years and 5 months later, the patient presented with nausea and headache, and recurrence of the tumour was revealed in the left lateral ventricle. The tumour was resected and histological diagnosis identified it as a choriocarcinoma. The patient was treated with chemotherapy and radiotherapy, but died due to dissemination 1 month later. An autopsy was not performed
