Background: Sellar cysts are common in neurosurgery. Around 90% of these are diagnosed as pituitary adenomas. The other 10% are nonadenomatous, inflammatory, infective, metastatic, or cystic in nature. Some rare cysts include dermoid, epidermoid, colloid, and arachnoid. They all have different histological features. The case we present demonstrates a unique cyst with features that are not previously documented. Case Description: A 60-year-old female presented to the neurosurgical department complaining of blurring of vision and severe headache for more than ½ year. Imaging was done which revealed a bony erosive lesion in the region of sella. Magnetic resonance imaging with contrast showed high signals with no contrast enhancement. A clear diagnosis could not be made based on radiology. Surgery was done and sample was sent for histopathology. Based on histopathological report findings, a diagnosis of benign atypical sellar cyst was made. Post procedure, the patient recovered and was discharged. Conclusion: Sellar cysts present similarly. They are differentiated based on their histological features. The sellar cyst we encountered had features different from the ones already described in the literature.

Abstract Background Management of postoperative chylothorax usually consists of nutritional regimens, pharmacological therapies such as octreotide, and surgical therapies such as ligation of thoracic duct, but a clear consensus is yet to be reached. Further, the variation of the thoracic duct makes chylothorax difficult to treat. This report describes a rare case of chylothorax with an aberrant thoracic duct that was successfully treated using focal pleurodesis through interventional radiology (IVR). Case presentation The patient was a 52-year-old man with chylothorax after a thoracoscopic oesophagectomy for oesophageal cancer. With conventional therapy, such as thoracostomy tube, octreotide or fibrogammin, a decrease in the amount of chyle was not achieved. Therefore, we performed lymphangiography and pleurodesis through IVR. The patient appeared to have an aberrant thoracic duct, as revealed by magnetic resonance imaging (MRI); however, after focal pleurodesis, the leak of chyle was diminished, and the patient was discharged 66 days after admission. Conclusions Chylothorax remains a difficult complication. Focal pleurodesis through IVR can be one of the options to treat chylothorax.

Plateau Fracture

Fat embolism syndrome (FES) is a complication of long bone fractures that often occurs within 72 hours of injury. Early-onset isolated cerebral fat embolism is catastrophic and rarely reported. We herein present a rare case of delayed-onset isolated cerebral FES that developed 10 days after definite fixation of a left tibial plateau fracture. A 70-year-old woman was injured in a traffic accident and diagnosed with a left tibial plateau fracture. However, she developed sudden loss of consciousness (E4V1M1) and quadriplegia 10 days after fracture fixation. Her vital signs showed no respiratory distress. Diagnosis of isolated cerebral FES was made based on magnetic resonance imaging of the brain, the findings of which were compatible with the clinical neurological findings. After supportive care and rehabilitation, her consciousness became clear on the second day of admission, and her consciousness changed to E4V5M6. She gradually regained strength in her right limbs but had residual left limb paraplegia. Isolated cerebral FES should always be considered for patients who develop a change in consciousness, even beyond 72 hours after injury. Imaging may not initially show definitive abnormalities. Repeated magnetic resonance imaging should be considered if the initial clinical presentation does not fully meet Gurd’s criteria.

TÓM TẮT U mỡ trong xương là khối u lành tính hiếm gặp, thường gặp ở các xương dẹt, hiếm gặp ở xương nền sọ, đặc biệt là xương bướm. Trong đa số các trường hợp, u mỡ trong xương bướm thường được phát hiện tình cờ qua chụp cắt lớp vi tinh (CLVT) hoặc cộng hưởng từ (CHT) sọ não. Đây là một khối u phát triển chậm, ít gây ra triệu chứng, một số trường hợp gây triệu chứng khi khối u to chèn ép vào cấu trúc lân cận như tuyến yên hoặc dây thần kinh thị. Trong bài này, chúng tôi báo cáo một trường hợp u mỡ trong xương bướm không triệu chứng được phát hiện tình cờ và được chẩn đoán dựa vào phim chụp cộng hưởng từ sọ não. Bệnh nhân được khuyến nghị theo dõi định kỳ bằng cộng hưởng từ mà không phải tiến hành bất kỳ phương pháp điều trị nào. Từ khóa: U mỡ, xương bướm, MRI, cộng hưởng từ sọ não, chẩn đoán hình ảnh. ABSTRACT INTRAOSSEOUS LIPOMA OF SPHENOID BONE: A RARE CASE REVIEW Intraosseous lipoma is very rare, usually benign tumor of flat bones. The incidence of an intraosseous lipomalocated basal skull bones is extremely rare, especially in sphenoid bone. Radiological imaging techniques such as magnetic resonance imaging (MRI) and computed tomography (CT) are used to detect the intraosseous lipoma by accident. These tumors are slow growing and usually asymptomatic, in some cases causing symptoms when the large tumor presses on nearby structures such as pituitary gland or the optic nerve. We present a rare case of lipomaof the sphenoid bone discovered incidentally with brain magnetic resonance imaging. The patient has been followed-up by magnetic resonance imaging without the need for surgery. Keywords: Intraosseous lipoma, sphenoid bone, MRI, brain MRI, diagnostic radiology

Background: Pure epidural spinal cavernous hemangiomas (SCH) account for only 4% of all spinal epidural lesions. Our literature review identified 61 publications reporting on, a total of 175 cases in the magnetic resonance imaging era. Here, we reviewed those cases, and have added our case of what appeared to be a multifocal SCH. Case Description: A 72-year-old male presented with a progressive paraparesis attributed to a T5/T6 dorsolateral extradural mass extending into the right T5/6 foramen. Surgical excision documented the lesion, histologically, was a SCH. A second similar lesion was noted involving the left C7/T1 foramen; as the patient was asymptomatic from this lesion, and no additional biopsy was performed. The patient returned to normal neurological function within 2 months postoperatively. Conclusions: Here, a 72-year-old male presented with a pathologically confirmed T5/T6 epidural SCH and a secondary C7/T1 foraminal lesion suspected to represent a secondary focus of an epidural SCH.

A 69-year-old man who had been bedridden in nursing home because of a 5-year history of progressive supranuclear palsy (PSP) was admitted due to aspiration pneumonia. Besides neck dystonia in extension, he showed “alternating flexed–extended posturing”, in which the arm was flexed on one side and extended on the other. Magnetic resonance imaging of the brain revealed global cerebral atrophy that predominantly affected the cortex and midbrain. The mechanisms of complex posturing in late-stage PSP may sometimes be related to decortication and decerebration as well as dystonia, and “alternating flexed–extended posturing” might be one of the phenotypes of pathological progression in PSP.

AbstractObjective:We present an extremely rare case of isolated angiokeratoma of the tongue.Method:Case report and review of related literature.Results:An 18-year-old, male adolescent presented with a fleshy, intermittently bleeding mass in the posterior third and base of the tongue. The lesion was initially suspected to be a lingual thyroid or haemangioma, but histopathological features were consistent with angiokeratoma. Magnetic resonance imaging revealed that the lesion extended up to the vallecula and involved the lamina propria and superficial tongue musculature. No similar lesions were found elsewhere in the body. No metabolic derangements were identified in the patient or his family. The 2.6 × 1.5 × 0.5 cm mass was excised under general anaesthesia.Conclusion:We present the 1st case of isolated lingual angiokeratoma in a male, the 4th such case overally, the largest ever documented. The lesion was situated in the posterior third and base of the tongue, a position not previously described.
