Cavernous hemangiomas of the temporalis muscle with prominent formation of phleboliths

Abstract

Rationale:Hemangiomas are benign tumors characterized by an abnormal proliferation of blood vessels, most often occur in the skin and subcutaneous tissue, intramuscular hemangioma, a distinctive type of hemangioma within the skeletal muscle, account for <1% of all hemangiomas, temporalis muscle is a very uncommon site, cavernous hemangioma of the temporalis muscle with prominent formation of phleboliths is rare reported.Patient concerns:A 62-year-old man presented with a slowly increased mass in his right temporal fossa.Diagnoses:Computed tomography (CT) scan showed the lesion across the zygomatic arch, with many calcified nodules differ in sizes and no erosion to the bone, magnetic resonance imaging (MRI) showed an oval lesion with hypointense and isointense on T2-weighted imaging within the temporal muscle, and preoperation diagnosis was hemangioma.Interventions:The tumor was resected under general anesthesia.Outcomes:The mass was excised completely, and the histopathology examination confirmed the diagnosis of cavernous hemangioma with prominent formation of phleboliths. The patient recovered very well without dysfunctions.Lessons:Cavernous hemangioma should be suspected when mass occurs in this region. CT and MRI are important for the early diagnosis of tumor, and resection the tumor completely is recommended.

Imaging Findings From Different Pathological Types of Oral and Maxillofacial Intramuscular Hemangiomas for Selecting Optimum Management

“…Pathologically, cavernous type of IMHs accounted for the majority and was expressed similar to venous malformations while the other 2 types were revealed as rich blood supply lesions. Most of the studies suggested that the imaging findings of oral and maxillofacial IMHs are consistent with venous malformations (6,(14)(15)(16)(17), and only a few studies indicated that the signal of IMHs lesions can be greatly enhanced (11,12); however, none of them neither has put forward the concept of rich blood supply status nor combined the enhancement with pathological types of IMHs for analysis. Through the comprehensive analysis of CT and MR images, we found that the capillary and mixed type of IMHs match with the characteristics of rich blood supply lesions, while cavernous IMHs were consistent with previous study results as relatively poor blood supply lesions.…”

A Case of Phlebolith with Cavernous Hemanjioma of The Head and Neck Region

“…Kalsiyum karbonat ve kalsiyum fosfat tuzlarının karışımından oluşan flebolit çekirdeği radyolojik olarak radyoopak ve radyolusent görünürler. Bu da lezyonun tipik soğan halkası benzeri görünümüne sebep olur 2,13,14 Histopatolojik olarak da radyolojisine benzer şekilde, konsantrik kalsifikasyonların yarattığı soğan halkası benzeri görüntüye rastlanır 4 . Benzer şekilde olgumuzda, radyolojik incelemelerde çoğunlukla hiperintens, yer yer hipointens alanlar içeren multipl kalsifiye nodüller izlendi.…”

Intramuscular hemangioma in the zygomaticus muscle: A rare case report presentation and diagnosis

“…The etiology of IMH is unknown, although trauma, abnormal embryonic tissue development, hormonal changes are considered predisposing factors in the growth of the IMH by stimulating more blood flow in the mass [ 3 , 4 ]. Initially, IMH clinically occur as a painless, slowly growing mass before making any noticeable symptoms [ 1 , 3 ].…”

“…IMH is a vascular benign proliferation that mostly occur in the skeletal muscles of the lower limbs and rarely in the head and neck area [ 3 ]. The etiology of IMH is not clear yet, although trauma, abnormal embryonic tissue development, hormonal changes are considered predisposing factors in the growth of the intramuscular hemangioma by stimulating more blood flow in the mass [ 3 , 4 ]. Intramuscular hemangioma, usually manifested clinically as painless, slowly growing with clear boundaries of the mass, and the development of calcified thrombi, which known as phleboliths [ 5 ].…”
