Aggressive vertebral hemangiomas contain no adipose tissue resulting in thoracic spine kyphosis: A case report.

RATIONALE: Aggressive vertebral hemangiomas (AVHs) destroy continuous vertebral bodies and intervertebral discs and resulting in spinal kyphosis is extremely rare. The very aggressive behavior was attributable to its significant vascular component and contained no adipose tissue. PATIENT CONCERNS: We report a case of thoracic spine kyphosis of AVHs with multiple vertebral bodies and intervertebral disc destruction in a 45-year-old woman. DIAGNOSES: Based on the imaging studies, the patient underwent surgical removal of this lesion and spinal reconstruction. Histopathology consistent with vertebral hemangioma and contained no adipose. INTERVENTIONS: The patient underwent surgical removal of the lesion and spinal reconstruction. After subperiosteal dissection of the paraspinal muscles and exposure of the laminae, the laminae of the T5-7 vertebrae were removed and exposing the lesion. The lesion was soft and showed cystic changes, completely curetted and autogenous bone was implanted. Vertebroplasty was performed through T3-T9 pedicles bilaterally. Pedicle screw fixation was performed for segmental fixation and fusion. OUTCOMES: After 9 days of operation, the incision healed cleanly and free of pain. She was discharged in good general condition. The patient remained asymptomatic after follow-up 6 months of postoperative. LESSONS: AVHs destroy multiple vertebral bodies and intervertebral discs and resulting in spinal kyphosis is extremely rare.

Surgery for a symptomatic massive liver haemangioma.

Liver haemangiomas are the most common benign hepatic tumours, but secondary portal hypertension resulting from haemangiomas is exceedingly uncommon. We present a case of a man in his 50s who presented with a progressively enlarging mass in the right upper abdomen. CT of the liver revealed a large hypodense lesion involving the right lobe, with two smaller lesions in the left lobe. The portal vein was compressed by the tumour, causing portal hypertension. The patient underwent right hepatectomy. Postoperatively, the patient had an uneventful course, and a 3-month follow-up demonstrated resolution of the oesophageal varices, portal gastropathy, with hypertrophy of the left lobe. This case report highlights the successful surgical management of a rare massive hepatic haemangioma causing portal hypertension with surgical resection, emphasising the potential benefits of surgical intervention with minimal complications.

Scientific validation of clinical visual scales and Antera 3D™ consistency with derived measurements in the assessment of infantile haemangioma after laser therapy.

BACKGROUND: Laser therapy is a treatment for infantile haemangiomas. The efficacy of laser therapy for red lesions is determined by visual evaluation; however, this assessment is inaccurate and lacks objectivity. OBJECTIVE: To scientifically validate the consistency between pre- and post-treatment visual assessment grades for infantile haemangioma treated with pulsed dye laser (PDL) and the values calculated from images obtained with Antera 3D™. METHODS: This study involved 81 cases of infantile haemangiomas treated with PDL alone from 2012 to 2015 and with Antera 3D™ images of the lesions. Using images obtained before treatment and 4-6 weeks after the last treatment, the lesions were rated using a visual four-step scale. Ratings were categorised as Poor/Fair/Good/Excellent by the degree of improvement in the red colour tone. The red colour ratio was calculated using the haemoglobin distribution in the lesion and surrounding skin, and the improvement difference and improvement rate were then obtained. The correlation between the improvement difference and improvement rate, and visual evaluation was statistically analysed. RESULTS: No serious adverse effects were observed, with an average of 4.3 treatments per patient; 60.1% of the patients achieved Good/Excellent results. There were statistically significant differences in the post-treatment red colour ratio and improvement ratio in each category after visual evaluation classification. The improvement rate and the four visual grades were statistically correlated. CONCLUSION: This study confirmed the scientific validity of visual evaluation and the evaluation criteria calculated from Antera 3D™. This method could objectively determine treatment effectiveness.

Intercostal hemangiomas coexisting with multiple hepatic hemangiomas: Clinical and imaging findings in a single case report with a review of the literature.

RATIONALE: Intercostal hemangioma (IH) is an extremely rare disease, with only 18 cases reported in the past 30 years. Herein, we report the first case of IH coexisting with multiple hepatic hemangiomas, which recurred 32 months after surgery with rib erosion. IHs are invasive and difficult to distinguish from other intercostal tumors on imaging. To date, there have been no review articles on the imaging findings of IHs. We hope that this article will help clinicians improve their ability to diagnose and treat IH. PATIENTS CONCERNS: A 58-year-old male came to our hospital with gastrointestinal disease. Chest tumors were accidentally discovered on routine chest computed tomography (CT). The patient had no chest symptoms. The patient also had multiple liver tumors that had been present for 2 years but with no remarkable changes. DIAGNOSIS: Plain chest CT revealed 2 adjacent masses protruding from the left chest wall into the thoracic cavity. Neurogenic tumors or hamartomas were suspected on enhanced CT scans. Abdominal contrast-enhanced computed tomography scan indicated multiple liver tumors as MMHs, which was consistent with the 2 previous Doppler ultrasound findings. INTERVENTIONS: Surgeons removed the chest tumors by video-assisted thoracoscopic surgery. No treatment was provided for the MMHs. OUTCOMES: Two tumors of the chest wall were diagnosed as the IHs. There were no significant changes in the hepatic tumors after 32 months of follow-up. Unfortunately, the IH recurred, and the left 5th rib was slightly eroded. LESSONS: It is necessary to include IHs as a potential differential diagnosis for chest wall tumors because early clinical intervention can prevent tumor growth and damage to adjacent structures. The imaging findings of IH show special characteristics. Preoperative imaging evaluation and diagnosis of IH are helpful for safe and effective surgery. Because of the high recurrence rate, complete surgical resection of IH with a sufficient tumor-free margin is recommended. It should be noted that the ribs should also be removed when the surrounding ribs are suspected to have been violated.

Endoscopic Submucosal Dissection: A Safe and Effective Alternative to Surgical Intervention for Esophageal Hemangioma.

BACKGROUND: Hemangiomas represent 3% of all benign esophageal tumors. Conventional esophagectomy is the standard treatment with its invasive nature and possible surgical complications. Now, less invasive techniques are used with better results. Endoscopic submucosal dissection (ESD) is one of the novel noninvasive methods used for en bloc removal of tumors. No available data about the use of ESD in removing esophageal hemangioma. Here, we studied the validity and safety of ESD as a minimally invasive procedure to remove esophageal hemangioma. METHODS: Three patients were diagnosed with esophageal hemangioma and underwent ESD with en bloc resection. Endoscopic ultrasound (EUS) was performed before ESD to better evaluate the layer of origin and vascularity and guard against perforation. Patients were followed up postintervention to document possible complications. RESULTS: Among the 3 studied patients, one presented with chronic abdominal pain, the second was complaining of dysphagia, and the third patient was diagnosed accidentally. Pathology reports confirmed the diagnosis of hemangiomas in all cases with no atypia and complete removal of the lesions. No complications were reported during the procedure or over the follow-up period. CONCLUSIONS: ESD is a proper, minimally invasive method with good en bloc resection that can be used in cases of esophageal hemangiomas.

Littoral cell angioma of the spleen: case report and literature review.

Littoral cell angioma is an extremely rare splenic vascular tumor originating from the cells lining the splenic red pulp sinuses. Approximately 150 cases of littoral cell angioma have been reported since 1991. Its clinical manifestation is usually asymptomatic and is mostly diagnosed as an incidental finding through abdominal imaging. Herein, we present a case of littoral cell angioma in a 41-year-old woman with no previous comorbidities, which initially presented as a nonspecific splenic lesion diagnosed on imaging in the emergency room. The patient was treated through laparoscopic intervention.

Intraosseous hemangioma with aneurysmal bone cyst-like changes of the hyoid bone: Case report and literature review.

RATIONALE: Intraosseous hemangioma is a rare benign vascular tumor of the bone that can affect any body part; however, the most common site is the vertebra, followed by calvarial bones. PATIENT CONCERNS: We present a case of intraosseous hemangioma in a 23-year-old male who presented a feeling of fullness in the throat for 3 months. The hyoid bone level had a hard mass of about 5 cm. Fine needle aspiration showed 5 mL dark bloody aspirates. Magnetic resonance image showed a 5.3 cm mixed signal intensity lesion in the hyoid body. DIAGNOSIS: Histopathologic examination showed intraosseous hemangioma with aneurysmal bone cyst (ABC)-like changes in the hyoid bone. INTERVENTIONS: The mass was completely removed without significant problems. OUTCOMES: Complete mass excision and symptomatic improvements were achieved, and no subsequent relapses were observed. LESSONS: The authors experienced a case of intraosseous hemangioma with ABC-like changes. There has been no case report of intraosseous hemangioma in the hyoid bone. This case showed a spectral pattern of the ABC-like changes developing from the underlying bone tumor as a secondary change. ABC-like changes in bone tumors can mislead the diagnosis. Careful examination of the tumor is essential for the correct diagnosis of ABC or ABC-like changes.

The chief culprit of intractable hypoxemia: a case report of rare pulmonary arteriovenous fistula complicated with giant hemangioma.

BACKGROUND: Pulmonary arteriovenous fistula (PAVF) is a rare disease, which can lead to the direct return of unoxidized venous blood to pulmonary veins and left heart, resulting in right-to-left shunt leading to hypoxia. Long term, the right-to-left shunt will cause severe pathophysiological changes in the patient's body and pulmonary circulation, and the prognosis will be poor if PAVF is not treated timely. CASE PRESENTATION: Here, we report the case of a 71-year-old man who presented with chest tightness and shortness of breath. After a series of examinations, PAVF and giant hemangioma were diagnosed, which are difficult to operate.Transcatheter interventional therapy was initiated. The patient recovered on the third day after operation and was discharged smoothly. During the long-term follow-up of nearly 4 years after discharge, the general condition and quality of life of the patient basically returned to normal. CONCLUSIONS: PAVF is rare but very important clinical problem. When the clinical manifestations of persistent unexplained hypoxia appear, it is necessary to fully consider the possibility of PAVF. Once the diagnosis of PAVF is clear, timely treatment is recommended to avoid deterioration of the disease and affecting the prognosis.

Management of a rapidly enlarging supraclavicular mass of unknown aetiology.

Intramuscular haemangiomas are benign tumours showing an extremely rare occurrence and making up less than 1% of all haemangiomas. The goal of this case report is to share our experience in treating a patient with an extremely rare intramuscular haemangioma, which occurred in the supraclavicular region VB level of the neck and extended towards the infraclavicular space, localised within and inferior to the trapezius muscle. The lesion was diagnosed by using multimodal imaging and a wide excision was performed with intraoperative feeding vessel ligation and a good postoperative result. The main difficulties regarding diagnosis and treatment include a lack of evidence-based guidelines, due to limited publications on this topic, the nature of the lesion frequently showing obscure anatomic localisation deep within muscles and unclear delineation, various anatomic origin requiring an individual treatment approach, inconclusive radiologic signs as well as non-specific symptoms.

Percutaneous Vertebroplasty for Cervical Symptomatic Hemangiomas and Spinal Metastases: A Case Series and Literature Review.

OBJECTIVE: Percutaneous vertebroplasty (PVP) is a commonly used technique for the treatment of spinal diseases, but it is rarely employed for cervical lesions. This study presents a case series and a literature review to evaluate the efficacy of cervical PVP. METHODS: From August 2013 to January 2023, 14 patients underwent cervical PVP in the author's institution. The mean postoperative follow-up time was 20.3 ± 12.1 months (ranging from 5 to 41 months). The pain status and quality of life were assessed preoperatively, postoperatively, and during follow-up using the Visual Analog Scale and Neck Disability Index. Additionally, complications that occurred during the study period were documented. RESULTS: The series of cases included 9 cases of hemangiomas and 5 cases of spinal metastases. The common symptom was axial pain in the neck. All patients were successfully treated with PVP. Visual analog scale scores decreased from 6.6 ± 0.8 preoperatively to 1.9 ± 0.8 at 24 hours postoperatively and to 2.4 ± 1.2 at the last follow-up (P < 0.01). Neck Disability Index decreased from 22.3% ± 8.9% preoperatively to 7.6% ± 8.1% at 24 hours postoperatively and to 6.0% ± 7.2% at 12-month follow-up (P < 0.01). After the operation, a case of dysphagia occurred, but no major complications were observed during the follow-up period. CONCLUSIONS: Cervical PVP via the anterolateral approach is a safe option for the treatment of cervical symptomatic hemangiomas and spinal metastases with limited invasiveness. It is effective in relieving pain and improving quality of life.

Giant Congenital Hemangioma of the Skull: Prenatal Diagnosis and Multimodal Endovascular and Surgical Management.

Introduction: calvarial capillary hemangiomas are vascular tumors rarely seen in newborns. Differential diagnosis may be not straightforward on imaging studies and the management depends on patient and lesion characteristics. Case report: we present the case of a large congenital intracranial extra-axial lesion detected by routine prenatal US screening, a giant calvarial congenital hemangioma, treated with a multimodal strategy. Neonatal MR showed a hemorrhagic solid lesion, causing compression of brain tissue. Conservative treatment was attempted, but a one-month follow-up MR showed growth of the lesion with increased mass effect. Pre-operative endovascular embolization and surgical resection were performed. The pathology was consistent with intraosseous capillary hemangioma. The post-operative course was uneventful. At the 8-month follow-up, the patient had no clinical deficits and MR showed complete resection of the lesion. At the 13-month follow-up, the patient was asymptomatic, showing normal neurological examination and psychophysical development. Conclusions: although wait-and-see policy is feasible for small and asymptomatic lesions, radical resection is indicated when the mass is large, thus causing severe mass effect on the brain. Hypervascularization of the tumor may be responsible for hemorrhagic complications and severe anemia. On these grounds, endovascular treatment is feasible and effective to reduce hemorrhagic complications.

A case report of hemorrhagic presentation of diffuse neonatal hemangiomatosis (DNH) associated to obstructive hydrocephalus: Medical and neurosurgical considerations.

BACKGROUND: Diffuse neonatal hemangiomatosis (DNH) is a rare disorder typically recognized at birth or during the neonatal period. DNH involves three or more organ systems, including the central nervous system (CNS). In these cases, serious complications such as hemorrhages and obstructive hydrocephalus can develop. CASE REPORT: We present a case of DNH with intracranial hypertension and CNS hemorrhagic lesions on the mesencephalic aqueduct, resulting in triventricular hydrocephalus, treated with endoscopic ventriculocisternostomy (ETV) and medical therapy. DISCUSSION: DNH is a rare condition that can involve the CNS with serious complications. From a review of the literature, we highlighted only two cases of DNH with brain involvement treated surgically. We report the successful outcome of ETV, along with surgical considerations, imaging findings, and the complete resolution of cerebral and skin lesions following medical therapy. CONCLUSIONS: Medical therapy is not standardized and must be individualized. In patients who develop severe neurological symptoms such as obstructive hydrocephalus, surgery may be considered to avoid neurological sequelae.

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.

Laparoscopic partial splenectomy in a patient with splenic hemangioma after distal gastrectomy for a neuroendocrine tumor.

Herein, we report the case of a patient with splenic hemangioma after distal gastrectomy who was treated with laparoscopic partial splenectomy. A 64-year-old woman previously underwent laparoscopic distal gastrectomy with regional lymph-node dissection for a gastric neuroendocrine tumor (G3) with venous infiltration and no lymph-node metastases. Periodic follow-up abdominal computed tomography revealed a well-defined, heterogeneous mass in the lower pole of the spleen 5 years after the operation, which grew from 12 to 19 mm 1 year later. A laparoscopic partial splenectomy was planned. During surgery, a smooth-surfaced mass with a lighter color than that of the surrounding area was observed at the lower pole of the spleen. The inferior polar branch of the splenic artery was transected, and the ischemic area of the lower pole of the spleen, where the tumor was present, was confirmed. First, the line used to perform splenic transection was determined using soft coagulation. The splenic parenchyma was then gradually transected using a vessel-sealing device system, and partial splenectomy was possible with almost no bleeding. The patient was discharged on postoperative day 8 without any complications. Pathological examination revealed a hemangioma without any malignant findings. Laparoscopic partial splenectomy is a safe and useful procedure that can be performed, considering the tumor size and location.
