“…Usually, a patient presents in childhood with a history of recurrent atraumatic painful bloody knee effusions [ 2 - 5 ]. These recurrent spontaneous hemarthroses of the knee joint and normal coagulation parameters should direct attention to the possibility of a synovial hemangioma.…”

“…On T2-weighted images the lesion exhibits a high signal (brighter than fat) correlating with stagnant blood in vascular spaces (Figures 2 and 3 ) [ 8 , 10 ]. Both T1-weighted and T2-weighted images contain characteristic lace-like or linear patterns due to the histological structure of synovial hemangioma [ 2 , 8 , 11 ]. The high signal intensity after intravenous gadolinium administration can permit their differentiation from muscle.…”

“…Most cases have been the intra-articular and intermediate type of hemangio-hamartoma, another form of vascular tumour of the leg representing an arteriovenous malformation which involves the synovia and causes intra-articular bleeding. Only a few of these have been true synovial hemangioma [ 1 , 2 ].…”

IntroductionSynovial hemangioma is a rare condition and is frequently misdiagnosed, leading to a diagnostic delay of many years.Case presentationWe present a case of an atypical synovial hemangioma in a 12-year-old Caucasian boy with a diagnostic delay of 3 years.ConclusionIt is important to know that synovial hemangioma mostly affects the knee joint, showing recurrent bloody effusions without a history of trauma. If there are no intermittent effusions, the diagnosis will be even more difficult. In cases of nonspecific symptoms and longstanding knee pain the diagnosis of a synovial hemangioma should also be considered in order to avoid diagnostic delay. Magnetic resonance imaging is the main diagnostic tool to evaluate patients with synovial hemangioma, showing characteristic lace-like or linear patterns.Angiography can identify feeder vessels and offers the possibility of embolisation in the same setting. Surgical excision, either done per arthroscopy or per arthrotomy, is recommended as soon as possible to avoid the risk of damage to the cartilage.

Case: Cavernous hemangioma, an uncommon benign vascular lesion, can affect different joints. It generally presents as atraumatic swelling over the joint with normal radiographic ndings. We present a case of a healthy 5-year-old girl with chronic knee pain over the anteromedial aspect following minor trauma. Conclusion:The patient underwent all baseline blood investigations and plain radiograph of her knee, all of which were normal. Magnetic resonance imaging showed hemangioma. Surgical excision was performed and histological studies con rmed a cavernous hemangioma. Delayed diagnosis may increase the risk of invading and damaging the joint resulting in further morbidities.
