척추 지주막낭의 수술적 제거 후 발생한 두개내압 상승에 기인한 난치성 두통

Increased intracranial pressure after arachnoid cyst resection is very rare. Previously, there were a few cases of intracranial hypertension after resection of intracranial arachnoid cyst or intracranial hypotension related to rupture of spinal arachnoid cyst, but no cases of intracranial hypertension related to the spinal arachnoid cyst. We report a case of intracranial hypertension after resection of spinal arachnoid cyst and describe the experience of treatment with temporary continuous lumbar drain for severe headache that did not respond to drug treatment.

The malignant transformation of benign intracranial epidermoid cysts is rare. Here, we report a case of an intracranial primary squamous cell carcinoma within an epidermoid cyst. Thus, we present this case along with a comprehensive review of the relevant literature. A 56-year-old woman presented with dizziness, tinnitus, and disequilibrium persisting for three months. Initial magnetic resonance imaging (MRI) indicated a neurogenic tumor on the right side of Meckel’s cave and bilateral vestibular schwannomas, suggesting neurofibromatosis type 2. However, follow-up MRI after two months revealed a significant increase in the size of the right Meckel’s cave tumor. Consequently, surgical resection was performed, which was initially considered a rapidly growing neurogenic tumor. Histopathological examination revealed a squamous cell carcinoma arising from an epidermoid cyst. Whole-body metastasis evaluation showed no primary tumors in other areas; however, leptomeningeal seeding at the sacral canal level was identified. Subsequently, the patient underwent craniospinal irradiation and chemotherapy, followed by radiation therapy. Although most epidermoid cysts follow a benign clinical course, we encountered an exceptionally rare case of malignant transformation originating from an epidermoid cyst. Because definitive management strategies are lacking, further clinical trials concerning the optimal treatment and outcomes of this disease are required.

Sixteen cases of intracranial arachnoid cyst were diagnosed with computerized tomography (CT). Four patients also had subdural hematoma, two of them following head trauma. Arachnoid cysts in Sylvian fissure are divided into three types, according to their shape and extension on CT. Male was predominant in sex distribution and Sylvian fissure was prevalent in location. Seizure and focal thinning of bone were the most frequently encountered clinical and radiological findings. Surgical procedure was performed in nine cases with partial excision of the cyst membrane or cystoperitoneal shunt. The authors discussed the pathogenesis, clinical findings and treatment of the intracranial arachnoid cyst. We support the congenital origin as pathogenesis, with the experience of one case, which was diagnosed before delivery with ultrasonogram. Considering the potential morbidity of the cyst, as subdural hematoma formation, we propose the surgical treatment as soon as the diagnosis is made.
Symptomatic Change of an Intracranial Neuroepithelial Cyst 7 Years After Its Incidental Finding
Ryoko Niwa 대한뇌종양학회 2022 Brain Tumor Research and Treatment Vol.10 No.1
A natural course of asymptomatic neuroepithelial cysts (NECs) is poorly understood due to its rarity. Herein we report a 23-year-old female patient of an asymptomatic NEC which grew in size from 1 cm to 5 cm and caused progressive symptoms seven years after its incidental finding. Partial resection of the cyst was performed for decompression and pathological examination and effectively achieved symptoms alleviation and regression of the cyst. Our case showed the importance of regular follow-up because NECs may show symptomatic change even in the late phase.

Intracranial dermoid cyst is a rare congenital disease originating in the embryo. Intracranial dermoid cysts are usually detected before five years of age; however, asymptomatic cysts have been discovered after the third decade of life through various complications. Sometimes, there are neurologic symptoms caused by a cys- tic mass effect and if there is a dermoid sinus, purulent infections can occur. Early diagnosis is important and as such, CT or MR imaging for recognition of the loca- tion, size, and characteristics of the cysts are recommended before surgical resec- tion. Extradural dermoid cysts with an intact occipital dermoid sinus are a rare event. We report a case of intracranial dermoid cyst associated with scalp abscess. In this case, a three-year-old boy was presented with scalp abscess and we per- formed MR imaging, which revealed a cystic region. The prognosis after resection operation was good without any complication.
Cystic Meningiomas: Correlation between Radiologic and Histopathologic Features
고경오,이광호,허원,이영석,박영섭,김성권,이정희,정진명 대한뇌종양학회 2018 Brain Tumor Research and Treatment Vol.6 No.1
Background Tumors with cysts often correlate with gliomas, metastatic tumors, or hemangioblastomas, which require differentiation. Methods Thirty-eight cases of cyst associated-meningioma based on preoperative radiologic studies and histologic confirmations were reviewed from November 1998 to July 2017. Results A total of 395 cases of meningioma were observed in the 20 years, and surgical treatment of intracranial meningioma was performed in 120 cases. Thirty-eight (9.6%) cases of cyst associated meningiomas were analyzed. Nauta type I was the most common type of cyst (39.5%) and the most frequent histopathological subtype was meningothelial type (36.8%). Conclusion Statistically there were no significant associations between meningioma histopathological type and associated cysts; however, the rate of World Health Organization grade II was higher in cyst associated meningiomas than in unrelated meningiomas. This correlation was weak, in accordance with the meningioma grade.

Occipital Intradiploic Epidermoid Cyst with Intracranial Hypertension
Park, Byung-Hyun,Lee, Hyun-Sung,Lee, Jong-Soo The Korean Neurosurgical Society 2006 Journal of Korean neurosurgical society Vol.40 No.5
Intradiploic epidermoid cysts of the cranium are rare, benign and slow growing lesion. However, these cysts may cause neurologic deficits due to mass effect. Intradiploic epidermoid cysts are thought to be derived from persistent ectodermal remnants present in the cranial bones during embryogenic development. Here, we report a case of an occipital intradiploic epidermoid cyst with posterior fossa extension. The patient developed intracranial hypertension associated with hydrocephalus due to aqueductal stenosis, and venous congestion secondary to compression of the torcular and the transverse sinus. The imaging studies included a computerized tomography[CT] venogram, which is essential for determining the pathophysiological mechanism of the clinical spectrum and for surgical planning. Near total removal was accomplished and the postoperative course was uneventful. Postoperative imaging studies demonstrated a reversal of the neural structures, but no patency of the sinus, which was presumably indicative of prolonged sinus stenosis. The patient gradually improved and was discharged free of symptoms.
Dermoid Cyst of Nasal Tip with a Sinus Tract Extending to the Intracranium: A Case Report
이승준,김성익,김민서,김종호 대한성형외과학회 2022 Archives of Plastic Surgery Vol.49 No.5
Nasal dermoid cysts are rare congenital anomalies that affect one in 20,000 to one in 40,000 individuals. Herein, we report a case of an initially misdiagnosed nasal dermoid cyst with intracranial extension. Among nasal dermoids, the lesion of the nasal tip is considered uncommon. Therefore, this should always be considered as a differential diagnosis of midline nasal masses, and a proper diagnostic approach should be taken.
