Isolated cavernous venous malformation of the eyelid.

Cavernous hemangioma, currently known as "cavernous venous malformation," is a common, benign, non-infiltrative, slowly progressive vascular malformation of the orbit presenting in adults. We report the case of a 9-year-old girl who presented with a painless palpable mass over the right upper eyelid of 7 years' duration. A computed tomography scan of the orbits revealed a heterogeneously enhancing, well-circumscribed mass in the right upper eyelid with no orbital extension. A transcutaneous excisional biopsy with histopathology disclosed cavernous venous malformation. The majority of cavernous venous malformations are intraconal and present in the fourth to fifth decade of life.

[Intraosseous cavernous hemangioma of the middle turbinate. Clinical cases]. / Vnutrikostnaya kavernoznaya gemangioma srednei nosovoi rakoviny. Klinicheskie sluchai.

Intraosseous vascular pathology of the turbinates is extremely rare in the practice of an otorhinolaryngologist and can be presented in various histopathological variants. The article presents two clinical cases in which an intraosseous cavernous hemangioma was hidden under the mask of a hypertrophied middle turbinate. The final diagnosis was established by the results of histological examination. The analysis of these clinical cases indicates that, despite the low prevalence, atypical clinical and CT picture, intraosseous formations of the nasal cavity can be of a vascular nature and certainly require a comprehensive examination, including CT, CT with contrast and/or MRI of the nose and paranasal sinuses. These clinical observations indicate that preliminary embolization of feeding vessels before surgical treatment is not required.

Optochiasmatic Cavernomas: Updated systematic review and proposal of a novel classification with surgical approaches.

Cavernomas are histologically benign vascular malformations found at different sites in the brain. A rare site for such cavernomas, however, is the anterior optic pathway, comprising the optic nerve, chiasma, and optic tract-called optochiasmatic cavernomas (OCC). These lesions usually present with sudden onset or progressive vision loss, headache, and features mimicking pituitary apoplexy. In this paper, we describe a case of OCC operated at our center. We carry out an updated review of literature depicting cases of OCC, their clinical presentation, management, and postoperative complications. We also propose a novel classification system based on lesion location and further analyze these cavernoma types with respect to the surgical approach used and visual outcome. A 30-year-old lady had presented with a 3-week history of progressive bilateral vision loss and headache. Based on imaging, she was suspected to have a cavernous angioma of the chiasma and left optic tract. Due to progressive vision deterioration, the lesion was surgically excised using pterional craniotomy. Postoperatively, her visual symptoms improved, but she developed diabetes insipidus. Clinical and radiological follow-up has been done for 18 months after surgery. A total of 81 cases have been described in the literature, including the present case. Chiasmal apoplexy is the most common presentation. Surgical excision is the standard of care. Our analysis based on lesion location shows the most appropriate surgical approach to be used for each cavernoma type. Visual outcome correlates with the preoperative visual status. Visual outcome is good in patients presenting with acute chiasmal apoplexy, and when complete surgical excision is performed. The endonasal endoscopic approach was found to provide the best visual outcome. In addition to preoperative visual status, complete surgical excision predicts favorable visual outcomes in OCC. Our proposed classification system guides the appropriate surgical approach required for a particular location of the cavernoma.

A rare case report of cervical hemangioma and a comprehensive literature review of 137 cases of cervical and uterine hemangiomas.

The cervix of the uterus is a rare site for cavernous hemangiomas. Cervical hemangiomas are slow-growing tumors with characteristic histological findings, including dilated vessels with increased endothelial cells. Although their pathophysiology remains unclear, hormones are believed to play an important role in the development of these vascular tumors. They may be asymptomatic due to their small size, but they can cause gynecological and obstetrical complications, including abnormal uterine bleeding and impaired fertility. Due to their small size, conservative treatment is the first line of management. Hysterectomy is considered for refractory cases or for patients who are not of childbearing age. In this study, firstly, we presented a case of a 60-year-old postmenopausal female without any gynecological-related signs or symptoms with a polypoid nodule hanging over the anterior cervical wall through its stalk. The surgical biopsy revealed no signs of neoplastic changes, with the only notable finding being a benign vascular lesion representing a cavernous hemangiomatous cervical polyp. The patient underwent a total abdominal hysterectomy and bilateral salpingo-oophorectomy and she is currently healthy without any further abnormal findings. Additionally, we provided a comprehensive review of 137 cases in the literature since 1883, detailing their characteristics, signs and symptoms, and pathology.

Precision Surgery for Orbital Cavernous Hemangiomas: The Role of Three-Dimensional Printing in Individualized Resection-An Educational Experience.

Orbital cavernous hemangiomas are the most common primary orbital tumors in adults, providing challenges for optimal surgical approach planning within an anatomically complex area with close proximity to vital neurovascular structures. The authors present an individualized lateral mini-orbitozygomatic approach for the resection of an orbital cavernous haemangioma based on a preoperative 3-dimensional-printed model. This individualized approach enabled the surgeons to achieve optimal exposure while maintaining safety during the resection of the lesion, but also to respect the patient's physiognomy and hairline. In addition, the model was used for patient informed consent, helping the patient understand the procedure. Although adding additional effort to preoperative planning, 3-dimensional model-based approaches can offer great benefits when it comes to customizing surgical approaches, especially for anatomically challenging resections.

Kimura's disease as a mimicker of cavernous hemangioma: A case report and literature review.

Kimura's disease (KD) is an immune-mediated disorder which mainly affects Asian men. It appears as head and neck subcutaneous masses, with inflammatory infiltrate and elevated serum immunoglobulin E levels. The clinical presentation of KD resembles that of various diseases. Here, we report the case of a 30-year-old Filipino man with KD mimicking cavernous hemangioma who was treated by surgery. Careful survey for possible KD cases is crucial. Misdiagnoses are prone to futile interventions and unwanted effects. Surgery with adjuvant therapy is superior to other forms of KD treatment.

Modified orbitozygomatic craniotomy with a single burr hole in the alternative sphenoid ridge keyhole.

BACKGROUND: One-piece modified orbitozygomatic approach (OZA) is an extended version of the pterional approach that also includes orbital walls and frontal process of the zygomatic bone. For this craniotomy one burr hole must be placed in MacCarty keyhole and another - in the temporal region. OBJECTIVE: To develop a technique of the one-piece modified OZA with single a burr hole in the alternative sphenoid ridge keyhole that allows access to orbit, anterior cranial fossa and middle cranial fossa and apply it intraoperatively. METHODS: A single human head specimen was used. The dissection was performed using standard surgical instruments high-speed Stryker drill. Every stage of the approach was photographed. We also report a surgical case of a patient with orbital cavernous hemangioma that was resected using the described technique. RESULTS: The technique of the one-piece modified OZA with a single burr hole in the alternative sphenoid ridge keyhole is described, and its advantages and limitations are analyzed. The technique is used to totally resect an orbital cavernous hemangioma with good functional and cosmetic result. CONCLUSION: Modified OZA with a single burr hole in the sphenoid ridge keyhole is possible and may be an alternative to the classic technique. The advantages of this variation are the placement of just one burr hole and the preservation of a larger portion of the orbital roof. The latter facilitates better bone reconstruction and better cosmetic outcome. Disadvantages are the difficulty of identifying the location of the sphenoid ridge keyhole and risk of damaging the dura.

Female Urethral Cavernous Hemangioma: Introducing Treatment and Follow-Up Course of Three Cases.

Cavernous hemangioma is a benign vascular tumor occurring in all parts of the urinary system, including the kidney, bladder, prostate, ureter, and rarely urethra. Urethral cavernous hemangiomas are mostly seen in male patients, and only a few cases of female urethral hemangiomas are reported. Herein, we present the management and follow-up course of 3 cases of female urethral cavernous hemangioma. All 3 cases were menopause women complaining of lower urinary tract symptoms. Definitive diagnosis is made by histopathologic evaluation. In case of large or pedunculated masses, initial surgical resection is highly recommended. Regular follow-up of patients in order to prevent any recurrence is suggested.

Primary Cavernous hemangioma of the Thyroid Gland. A series of 4 cases and review of literature.

Cavernous hemangiomas can arise nearly anywhere in the body where there are blood vessels. The primary hemangioma of the thyroid gland is extremely rare, and only a few cases have been previously reported. The true incidence of cavernous hemangiomas is difficult to estimate because they are frequently misdiagnosed as other venous malformations. We will present 4 cases from the age of 38 to 72 years old, diagnosed with cavernous hemangiomas. All 4 cases are women and the diagnosis was established after total thyroidectomy by histopathological examination. They clinically present as asymptomatic cervical tumors, are occasionally fast-growing, especially if intratumoral bleeding is present. KEY WORDS: Cavernous Hemangioma, Thyroid, Pathology, Histology.

Unilateral chorea linked to cavernous haemangioma involving the putamen improved by surgery.

Unilateral chorea movements caused by cavernous haemangioma in the putamen are extremely rare. We report a case with chorea movements linked to cavernous haemangioma, localised to an area including the putamen in which pharmacotherapy was found to be ineffective. Symptoms were, however, improved by resection of the cavernous haemangioma. In cases where chorea movements linked to cavernous haemangioma, involving the putamen, prove intractable with watchful waiting or pharmacotherapy, improvement can be expected with surgical removal of the cavernous haemangioma. It is also possible to reduce the risk of complications through the use of intraoperative navigation and monitoring.

[Primary intraosseous cavernous hemangioma of the cranium: a case report]. / Pervichnaya vnutrikostnaya kavernoznaya gemangioma kostei cherepa: obzor literatury i opisanie klinicheskogo nablyudeniya khirurgicheskogo lecheniya.

Primary intraosseous cavernous hemangioma (PICH) is a rare benign vascular tumor. This neoplasm is common in the spine and less common in skull. Toynbee J. first described this tumor in 1845. PICH of the cranium does not always have typical X-ray features and should be always differentiated with other more common skull lesions. Surgical resection is preferable since total resection is followed by favorable prognosis. We present a 65-year-old patient with asymptomatic tumor of the right parietal bone. CT revealed osteolytic lesion that required total resection and skull repair. Histopathological analysis revealed intraosseous cavernous hemangioma.

Abnormal clinical presentation and surgical outcome of an intraventricular cavernoma of the third ventricle.

We present a unique case of a man presenting with progressive short-term memory deficits over 10+ years who was found to have a large intraventricular cavernoma in the anterior wall of the third ventricle with invasion of medial limbic structures. Identifying intraventricular cavernomas early is crucial to prevent substantial growth and to increase the chance of successful patient outcomes.

Stereotactic radiosurgery for orbital cavernous hemangiomas.

OBJECTIVE: The goal of this study was to assess the safety and efficacy of single-session Gamma Knife radiosurgery (GKRS) for orbital cavernous hemangiomas (OCHs). METHODS: Patients who presented with an OCH between September 1999 and May 2022 and were treated with single-session GKRS were included in this single-center cohort study. RESULTS: There were 23 patients (7 males and 16 females) in this study. The median margin dose was 12 Gy (range 11-13 Gy). The median clinical and radiological follow-ups were 45 months (range 5-190 months) and 45 months (range 6-190 months), respectively. Nine (69.2%) of 13 patients with visual acuity impairment had improvement in best corrected visual acuity. Of the 8 patients with visual field defects, 5 patients (62.5%) had complete resolution. Tumor regression was observed in 22 patients (95.7%). The mean relative reduction in tumor volume was 82.6% ± 23.7%. The relative reductions in tumor volume were 33%, 49%, 72%, 84%, and 89% at 6, 12, 24, 36, and 48 months, respectively. Adverse effects of radiation were not observed. CONCLUSIONS: GKRS appears to be safe and efficacious for treating OCHs over long-term follow-up. The treatment is associated with a high rate of regression in OCHs and remarkable improvement in both visual acuity and visual field deficits.

A step-by-step commentary of surgical footage is provided along with clinical, anatomical and technical learning points pertinent to the safe surgical management of these lesions.

[Prognosis of patients with spinal intramedullary cavernous hemangioma by different treatments].

OBJECTIVE: To investigate the improvement of spinal cord function in patients with spinal intramedullary cavernous hemangioma (SICH) treated with different methods at the last follow-up. METHODS: A retrospective study of 30 patients with SICH in Peking University Third Hospital from January 2007 to December 2018 was conducted. Clinical data of 30 patients were collected including gender, age, clinical symptoms, and imaging manifestations were acquired from their clinical records. Spinal functions of the patients with SICH were evaluated by European myelopathy score (EMS). The functional status of the spinal cord before and after the last follow-up were analyzed. RESULTS: Among the 30 patients, there were 14 male patients and 16 female patients (1 ∶ 1.14). The average age of the patients was (48.1±13.6) years (18-81 years). In the study, 3 cases were sensory disturbance; 2 cases manifested with only decreased muscle strength; 1 case showed simple pain; 1 case manifested with decreased muscle strength and pain; Sensory disturbance accompanied by decreased muscle strength occurred in 5 cases; 3 cases suffered from both sensory disturbance, decreased muscle strength and abnormal defecation; 3 cases suffered from sensory disturbance, decreased muscle strength and pain; 8 cases showed sensory disturbance and pain; 1 case had sensory disturbance, pain and abnormal defecation; 1 case had sensory disturbance, pain, decreased muscle strength and abnormal defecation; 2 cases were asymptomatic. There were 11 patients whose lesions were located in the cervical region, 2 patients located at the cervical-thoracic region, 15 patients located in the thoracic region, and 2 patients located in the lumbar spine. The average maximum diameter of hemangioma was (10.90±4.87) mm. Their magnetic resonance imaging (MRI) features were usually mixed signal and high signal on T2WI, and equal signal or mixed signal on T1WI. A total of 30 patients were followed up for (27.4±8.7) months, including 19 patients with surgical treatment and 11 patients with conservative treatment. The spinal cord function at the last follow up in surgical group was significantly improved. The difference was statistically significant (P < 0.05). Only one patient' s symptom in conservative treatment group improved. However, the symptoms of the two patients aggravated. Other patients remained stable. There was no significant difference in spinal cord function before and after treatment (P>0.05). CONCLUSION: The surgical treatment of SICH has obvious positive effect and good prognosis. The overall improvement rate of conservative treatment is relatively low with a risk of aggravation.
