“…Diagnosis is accomplished by past history and physical exam, aided by angiography, CT, MRI, or Doppler flow studies. Treatment for pseudoaneurysms are often managed by surgical resection, but other methods including manual compression, percutaneous suturing, direct thrombin injection, and direct puncture embolization have been reported effective [1,10]. All patients in this study were treated by surgical resection without recurrences.…”

“…In this report, we describe four such cases. It has been proposes that in the scalp, the location of the superficial temporal artery subjects it to common injury, in addition to the fact that there is no protecting surrounding muscle [10]. Common presenting symptoms are tender, pulsatile lesions that develop in the anterior temporal region the frontotemporal region 2 weeks to 4 months after a blunt or penetrating trauma [1].…”

Objectives Most cases of pediatric scalp and skull masses are either congenital or developmental tumors or diseases, and in many patients, these lesions are accompanied by intracranial extension. Past studies pertaining to these conditions are few, and thus clinical information is as yet inadequate. Materials and methods The authors present 75 pediatric patients with 77 cases of surgically treated scalp and skull masses. The most common pathologic condition was Langerhans cell histiocytosis, followed by epidermal cysts, epidermoid and dermoids, scalp hemangiomas, and neurofibromas, in descending order. Intracranial extension was observed in three cases (4%); two cases were malignant tumors that were skull metastasis of a neuroblastoma and a lymphoma, and one case was encephalocele. Lesions followed up because of possible recurrence were 15 cases of Langerhans cell histiocytosis, eight cases of epidermoid and dermoids, two cases of malignant tumors, and one case each of desmoplastic fibroma, myxoma, fibroid dysplasia, and neurofibroma, totaling 29 cases (39%). Conclusion Although the overall incidence of intracranial extension of pediatric scalp and skull masses is very low and the presence of a malignant tumor or metastatic tumor presenting as a scalp and skull mass is rare, such masses enlarge as time progresses, and there exists a possibility of recurrent disease. Therefore, it is suggested that early surgical resection will afford favorable prognosis for the patients, and meticulous follow-up is necessary in some conditions.

“…1 Although computed tomography (CT) and angiography can be helpful in the diagnosis of pseudoaneurysms, superficial aneurysms are typically removed by simple surgical excision without an extensive preoperative evaluation. [1][2][3][4][5][6][7][8][9][10][11] The pulsatile characteristics pointing to the diagnosis may be minimal or absent. 12 However, the vascular repair process in areas of increased tensile strength gives rise to the unique histologic features of pseudoaneurysms.…”

Superficial temporal artery pseudoaneurysm: what is the role of ultrasound?

Purpose The superficial temporal artery (STA) is one of the terminal branches of the external carotid artery; STA pseudoaneurysms are uncommon vascular lesion, generally subsequent to blunt or penetrating trauma that could represent a trick for radiologist, especially when the only anamnestic information is ''palpable superficial swelling''. In this article, we describe our ultrasonographic experience about STA pseudoaneurysm reporting several cases with different etiopatogenesis. Methods Between January 2004 and March 2015 six patients (4F and 2M; aged 15-55 years, mean 36 year) presented at our department with superficial palpable swelling in temporal region (four with trauma history, two with iatrogenic cause) underwent to ultrasonographic study to assess the presence of STA pseudoaneurysm. Ultrasonographic findings suggestive of pseudoaneurysm was a well-defined, pulsatile, anechoic mass in B-mode, a swirling or disorganized pattern of blood flow in the lesion with demonstration of direct communication between arterial lumen and pseudoaneurysm at colour-Doppler and a typical to-and-fro waveform on pseudoaneurysm neck at pulsed-Doppler.Results B-mode proves the presence of anechoic mass in five on six patients. Colour-Doppler demonstrates the presence of flow inside the lesion in five patients and a direct communication in all patients. To-and-fro typical waveform has been demonstrated in five patients. Ultrasound made diagnosis in all patients with a sensibility and specificity of 100 %. Conclusion US is the imaging modality of choice, since it can provide detailed information about vascular anatomy without incurring the risks of invasive methods like angiography or radiation.Keywords Pseudoaneurysm Á Superficial temporal artery Á Sonography Á Colour Doppler Riassunto Scopo L'arteria temporale superficiale (STA) è uno dei rami terminali della carotide esterna. Gli pseudoaneurismi dell'STA sono poco frequenti, generalmente successivi a traumi chiusi o penetranti, potendo trarre in inganno il radiologo soprattutto quando l'unica informazione anamnestica è ''rigonfiamento superficiale palpabile''. In quest'articolo descriviamo la nostra esperienza ultrasonografica riguardo gli pseudoaneurismi dell'STA riportando diversi casi ad eziopatogenesi diversa. Metodi Tra il Gennaio 2004 e Marzo 2015 6 pazienti (4F E 2M; Età 15-55 anni, media 36) giunti al nostro dipartimento per un rigonfiamento superficiale palpabile in regione temporale (4 con storia di trauma, 2 per cause iatrogene) vengono sottoposti ad esame ecografico per valutare la presenza di pseudoaneurismi dell'STA. I reperti ultrasonografici suggestivi per pseudoaneurisma sono stati: una massa ben definita, anecogena e pulsatile in B-mode, un pattern di flusso turbolento all'interno della lesione con la dimostrazione di una diretta comunicazione tra il lume (2016( ) 19:197-201 DOI 10.1007 arterioso e lo pseudoaneurisma al color-Doppler e un tipico spettro flussimetrico ''to-and-fro'' in corrispondenza del collo aneurismatico.
