RESUMO

OBJECTIVE: To explore the clinical, imaging, pathologic characteristics and differential diagnosis of solitary pulmonary capillary hemangioma (SPCH). METHODS: Thirty two cases of SPCH were collected and studied, with literature review. RESULTS: This study included 13 males and 19 females, with a male-to-female ratio of 1:1.5. The age ranged from 26 to 70 years (median age of 43 years). All patients were asymptomatic at presentation. Lung nodules were incidentally discovered during chest computed tomography (CT). Imaging features included 21 cases with partial solid nodules (PSN), 7 cases with ground-glass nodules (GGN), and 4 cases with solid nodules (SN). Eleven cases were in the left lung lower basal segment, 11 cases in the right lung lower basal segment, 6 cases in the right lung upper anterior segment, and 4 cases in the right lung middle lateral segment. The lower basal segments of the lungs were involved in 22 (11 in each lung) cases (22/32, 68 %). The tumors ranged from 6 to 18 mm (average 10 mm). Macroscopically, 16 cases had clear boundaries, while 16 cases had unclear boundaries, and gray-red or dark brown on cut surfaces. Intraoperative frozen section was performed in 27 cases, with diagnosis of SPCH in 12 and pneumonia or inflammatory lesion in 15. Microscopically, the nodules were composed of densely proliferated and dilated capillaries. The capillary walls were lined with a single layer of flat endothelial cells, without atypical features. Collapsed alveolar septa were replaced by a large number of capillaries. All cases showed proliferating capillaries spreading into the walls of small veins/arteries and bronchi, with 3 cases showing dilated capillaries protruding into the bronchiolar lumens as polyp-like structures. Twenty-six cases (26/32, 81 %) showed proliferating capillaries passed over the interlobular septa. Twenty-six cases (26/32, 81 %) showed irregular intimal thickening of small muscular arteries in the peripheral areas of the lesions, with the thickened intima being cellular or fibrous. In twenty-seven cases (27/32, 84 %) the lesions were located in the subpleura, with 6 cases involving the pleura. CONCLUSION: SPCH is a rare benign lung tumor that mostly occurs in the lung lower basal segments with predominance in females. It usually appears as a ground-glass nodule on CT and is very similar to early-stage lung cancer. Accurate diagnosis requires collaboration of radiologists, surgeons, and pathologists. SPCH should be regarded as an important differential diagnosis of small incidental lung nodules.

RESUMO

We present the case of an infant with rapidly progressing orbital tumor that had initial radiological and clinical features of both rhabdomyosarcoma and capillary hemangioma. The patient was eventually diagnosed with malignant rhabdoid tumor of the orbit. We discuss the salient histological and radiological features of our case and review the literature on orbital malignant rhabdoid tumors.

RESUMO

ABSTRACT: A 67-year-old woman was enrolled in our 68 Ga-FAPI PET/CT tumor clinical trial due to her lung adenocarcinoma. The PET/CT scan additionally revealed increased uptake of FAPI in the tongue. Combined with the patient's medical history and the contrast-enhanced CT of the maxillofacial region, it was suspected to be a hemangioma. Subsequently, the patient underwent surgery and was diagnosed with capillary hemangioma of the left side of her tongue.

RESUMO

BACKGROUND: Capillary hemangiomas are rare vascular lesions that rarely affect the central nervous system. When they present within the spinal canal, they are typically confined intradurally, with intramedullary extension rare. We present a rare case of spinal intramedullary capillary hemangioma, with a systematic review of the literature. METHODS: Medical records and imaging data were retrospectively reviewed using the health record software EPIC (Verona, Wisconsin, USA) and the radiology management software system RIS/PACS (Radiology Information System/Picture Archiving and Communication System; QREADS). The report was written in accordance with the CARE (case reports) guidelines. We also performed a systematic review of the literature on all cases of intramedullary spinal capillary hemangiomas in accordance with PRISMA (preferred reporting items for systematic reviews and meta-analyses) guidelines. RESULTS: We report a case of a 54-year-old man who presented with progressive paraplegia and sensory deficits in the lower extremities. Spinal magnetic resonance imaging showed an intramedullary enhancing lesion centered at T11 with associated spinal cord compression. He underwent thoracic laminectomy and gross total resection of the lesion without complications and subsequent improvement on his neurological examination. Histological examination showed findings consistent with a capillary hemangioma. The literature review also documented 21 studies with a combined total of 38 cases of intramedullary spinal capillary hemangioma. CONCLUSIONS: Purely intramedullary capillary hemangiomas are unusual spinal lesions with only a few cases reported in the literature. These should be considered in the differential diagnosis of intramedullary tumors. Surgical management remains the first line of treatment for symptomatic patients.

RESUMO

Spinal intramedullary capillary hemangioma is a rare condition. Although most spinal/spinal cord hemangiomas are inborn in origin, perinatal presentation is uncommon. We present a neonate with an intramedullary hemangioma, born with communicating hydrocephalus and complete paraplegia. Spinal imagining showed an intradural mass with hemorrhagic foci, a low-lying conus medullaris, and scalloping of dorsal elements. Ventriculoperitoneal shunting was performed in an emergent setting, with cerebrospinal fluid showing a brownish appearance with high viscosity which implied a possible old hemorrhage. Tissue sample was taken from the spinal lesion in an elective setting. Histopathological examination revealed capillary lobules and extralobular large vessels resembling abnormal veins. The mentioned clues suggested that this congenital hemangioma had become symptomatic from the prenatal period. Though it is a are event, it should be kept in mind while evaluating a neonate with communicating hydrocephalus and weakness of extremities with or without cutaneous hemangiomatous stigmata.

RESUMO

Background and objectives: Capillary hemangiomas are rare, benign vascular tumors that mainly affect the skin and soft tissue, with scarce appearance within the nasal cavities and paranasal sinuses. Materials and methods: We present a case report of capillary hemangioma of the sphenoid sinus and a review of the literature in the last ten years. Results: Clinical and endoscopic examination of the nose, radiologic assessment and particular histologic features contribute to the correct diagnosis of capillary hemangioma of the nose and paranasal sinuses. Conclusions: Transnasal endoscopic resection of capillary hemangioma located in the nose and paranasal sinuses is a valuable treatment method with good outcomes.

RESUMO

Intramuscular capillary-type haemangiomas (ICTH) are rare vascular anomalies that can easily be misdiagnosed as other entities. A systematic review was performed of all cases of ICTH in the literature since its first description in 1972. An adjudication committee reviewed cases to include only ICTHs. Among 1,143 reports screened, 43 were included, involving 75 patients. The most frequent differential diagnosis was intramuscular venous malformations. The mean age of patients at diagnosis was 21.2 years. ICTH was mainly described as a gradually increasing mass (81.8%), painless (73.9%), that could occur anywhere in the body but most frequently on the head and neck (44.0%). Magnetic resonance imaging (MRI) was mainly used for diagnosis (69.1%) and displayed specific features. The most frequent treatment was complete surgical removal (73.9%), which could be preceded by embolization, and led to complete remission without recurrence in all but 1 case.

RESUMO

This article presents the case of a 33-year-old woman who consulted the authors' ENT clinic in the 39th week of pregnancy with recurrent epistaxis. A livid endonasal mass was found on the left side, subtotally displacing the nose and leading to deformation of the external nose. External biopsy provided no indications of malignancy. Postpartum CT of the paranasal sinuses revealed a mass destroying the cartilaginous nasal septum. Endoscopic resection of the finding was performed with preservation of the clinically sound nasal septal cartilage. Histopathological examination revealed a capillary hemangioma, which was classified as granuloma gravidarum due to its occurrence during pregnancy.

RESUMO

BACKGROUND: Almost all of the epidural hemangiomas reported are cavernous hemangiomas. Purely extradural spinal capillary hemangiomas are very rare. Capillary hemangiomas are hamartomatous malformations that result from proliferations of vascular endothelial cells. Only ten cases have been reported in the English literature, treated with surgical excision. CASE DESCRIPTION: A case of a dorsal extradural spinal capillary hemangioma is described. A total surgical removal has been performed after spinal angiography and embolization. Complete surgical removal should always be the goal in these lesions. Embolization did not show to reduce bleeding during the surgical procedure in this case.

RESUMO

In this article, the authors report their management with minimally invasive surgery and embolisation of a bulky intramuscular capillary haemangioma. Masseteric capillary haemangioma is a rare tumour in adults: in cases of large-sized tumours we suggest a multidisciplinary approach in choosing the best treatment and minimally invasive, scarless surgery.

RESUMO

We present the case of a fetus with cardiac capillary hemangioma in the right atrial cavity. The tumor showed dramatic growth between the 28th and 32nd week of gestation and resulted in tachyarrhythmia. The patient was born at the 33 weeks of gestation weighing 2430 g via urgent cesarean section because the rapidly growing cardiac tumor caused incessant tachyarrhythmia, pericardial effusion, and fetal circulatory incompetence. Coronary angiography revealed that the right coronary artery drained into the tumor. Due to hemodynamic deterioration, the patient underwent subtotal resection of the tumor on the 2nd day after birth. Histopathological examination revealed an undifferentiated capillary hemangioma. The patient was discharged at the age of 86 days, as the tachyarrhythmia and hemodynamic incompetence had subsided; however, bradycardia and intermittent atrioventricular conduction disturbance gradually developed. Capillary hemangioma, a rare primary cardiac space-occupying tumor in children, can invade the conduction system.

RESUMO

BACKGROUND AND IMPORTANCE: Capillary hemangiomas are space-occupying lesions that rarely affect the central nervous system. When they present within the spinal canal, they can cause insidious symptoms and threaten neurological function. In this study, we present a case of an intradural extramedullary capillary hemangioma of the lumbar spine, discuss our management strategy, and review the current literature. For the first time for this diagnosis, we also provide an operative video. CLINICAL PRESENTATION: The patient is a previously healthy 40-year-old man who presented with complaints of progressive low back and leg pain, numbness, and intermittent subjective urinary incontinence. MRI revealed a discrete, homogenously enhancing intradural extramedullary lesion at L4. This lesion was resected by performing an L4 laminoplasty, which entails en bloc removal of the L4 lamina and then securing it back into place once the intradural resection and dural closure are completed. Histological analysis revealed a diagnosis of capillary hemangioma. The patient had full resolution of his symptoms postoperatively. DISCUSSION: Definitive management of spinal capillary hemangiomas involves gross total resection and can be accomplished with laminoplasty. Because these benign tumors can be adherent to adjacent structures, intraoperative neuromonitoring is helpful adjunct to preserve neurological function for a good outcome. CONCLUSION: Capillary hemangiomas rarely affect the spine but should be considered on the list of differential diagnoses of intradural lesions.

RESUMO

BACKGROUND: In the stratification of potential causes of PH, current guidelines recommend performing V/Q lung scintigraphy to screen for CTEPH. The recognition of CTEPH is based on the identification of lung segments or sub-segments without perfusion but preserved ventilation. The presence of mismatched perfusion defects has also been described in a small proportion of idiopathic pulmonary arterial hypertension (PAH) and pulmonary veno-occlusive disease and/or pulmonary capillary hemangiomatosis (PVOD/PCH). Dual-energy CT lung perfusion changes have not been specifically investigated in these two entities. PURPOSE: To compare dual-energy CT (DECT) perfusion characteristics in PAH and PVOD/PCH, with specific interest in PE-type perfusion defects. MATERIALS AND METHODS: Sixty-three patients with idiopathic or heritable PAH (group A; n = 51) and PVOD/PCH (group B; n = 12) were investigated with DECT angiography with reconstruction of morphologic and perfusion images. RESULTS: The number of patients with abnormal perfusion did not differ between group A (35/51; 68.6%) and group B (6/12; 50%) (p = 0.31) nor did the mean number of segments with abnormal perfusion per patient (group A: 17.9 ± 4.9; group B: 18.3 ± 4.1; p = 0.91). The most frequent finding was the presence of patchy defects in group A (15/35; 42.9%) and a variable association of perfusion abnormalities in group B (4/6; 66.7%). The median percentage of segments with PE-type defects per patient was significantly higher in group B than in group A (p = 0.041). Two types of PE-type defects were depicted in 8 patients (group A: 5/51; 9.8%; group B: 3/12; 25%), superimposed on PH-related lung abnormalities (7/8) or normal lung (1/8). The iodine concentration was significantly lower in patients with abnormal perfusion (p < 0.001) but did not differ between groups. CONCLUSION: Perfusion abnormalities did not differ between the two groups at the exception of a higher median percentage of segments with PE-type defects in patients with PVOD/PCH. KEY POINTS: • Patchy perfusion defect was the most frequent pattern in PAH. • A variable association of perfusion abnormalities was seen in PVOD/PCH. • Lobular and PE-type perfusion defects larger than a sub-segment were depicted in both PAH and PVOD/PCH patients.

RESUMO

BACKGROUND: Infantile hemangiomas are vascular anomalies. However, they rarely cause genital bleeding. Here, we present the case of a young female with an endocavitary hemangioma who presented with abnormal uterine bleeding (AUB). CASE: The patient was an 8-year-old female with genital bleeding. Transabdominal pelvic ultrasound showed a 20-mm highly vascularized focal intrauterine endocavitary lesion. Vascular computerized tomography excluded vascular anomalies. Magnetic resonance imaging suggested a hemangioma. Minimally invasive open surgery was performed to remove the lesion. Subsequent pathology analyses confirmed an infantile/capillary hemangioma. CONCLUSIONS: Infantile hemangiomas are vascular anomalies that should be considered potential causes of AUB in early puberty. The study of these cases should include pelvic ultrasound and vascular magnetic resonance imaging. Experienced surgeons can successfully accomplish fertility-sparing surgical procedures. SUMMARY: We describe an unusual case of peripubertal AUB caused by an endocavitary capillary hemangioma. Management included fertility-sparing surgery and the complete resolution of symptoms.

RESUMO

Capillary hemangiomas are benign vascular lesions that are common in head and neck, but hemangiomas of jugular foramen and temporal bone are rare with only a few cases reported in the literature. We present a case report of this rare disease entity highlighting the subtle radiographic nuances that can benefit clinicians when encountered with similar unusual clinical scenario. Although radiographic features of capillary hemangioma can be distinctive, they are not specific. In this case, the lack of significant involvement of the jugular bulb and the absence of the typical pattern of osseous erosion of the jugular carotid spine led to the alternative diagnosis of a rare capillary hemangioma of the jugular foramen.
