“…[24] In recent years, case reports of benign or malignant tumors and tumor-like lesions located in the ramus ischium or pubic ramus have been reported. [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] In this study, which included 31 cases, the statistical analysis of the data found that the lesions were located more frequently in the pubic ramus, and the lesions located in the ramus ischium were found to have significantly higher risk of malignancy than tumor-like lesions.…”

Primary benign and malignant bone tumors and metastases can be located in pelvic ramus. [1-4] In addition, non-tumor benign processes can be confused with tumor lesions. [5-7] Considering all tumors that settle in the ramus, although there are no data about the incidence of ramus tumors in the literature, chondrosarcoma (CS) is the most common tumor when the case reports are examined. [3,4,8-10] Also, the most common benign tumor is aneurysmal bone cyst (ABC). [11-14] Ramus tumors can be seen in a wide range of ages. [10,15] Patients usually present with symptoms of inguinal pain, swelling, or both. [2,15,16] Examination findings usually include a mass or sensitivity in that area. Some patients are detected by coincidental lesions on radiographs. [4,17,18] In almost all lesions, firstly, the lesion is detected by direct radiographs and further examinations are performed such as magnetic resonance imaging (MRI) or computed tomography. The treatment of tumors located in ramus varies according to tumor type. Follow-up, excision/curettage + adjuvant therapies or en-bloc resection can be performed in benign tumors. [2,4,6,15,16,19] In malignant tumors and metastases, wide resection (en-bloc resection of Objectives: This study aims to investigate the characterization, treatment approaches, and follow-up results of tumors and tumor-like lesions located in the pelvic ramus. Patients and methods: Thirty-one patients (9 males, 22 females; mean age 48.9 years; range, 7 to 79 years) with benign and malignant tumors or tumor-like lesions in the pelvic ramus region treated and followed-up in our clinic between January 2005 and January 2019 were evaluated retrospectively. Surgical procedures were performed with anterior approach or inner-thigh approach. Twelve patients were diagnosed with malignant tumors, 12 patients with benign tumors, and seven patients with tumor-like lesions. Results: Seventeen patients who underwent surgical treatment were followed-up for a mean period of 61.7 months. The diameters of benign and malignant tumors were similar (p=0.425). Of all lesions, 64.5% were located in the pubis. Ischium location was significantly higher in patients with malignant lesions than tumor-like lesions. The most common complication was diffuse subcutaneous edema in the inguinal region and thigh (8.3%). Conclusion: There are many different tumoral lesions in the pelvic ramus. Pelvic ramus tumors tend to settle more frequently in pubic ramus, whereas ramus ischium tumors are more likely to be malignant. In addition, the diagnosis of insufficiency fracture should be considered primarily in pathologic fractures of pubic ramus in females over 50 years of age. In the postoperative follow-up of pelvic ramus tumors, diffuse edema may occur even if there is no intraoperative vascular damage.

“…In contrast, Khan et al 17 ‎did curette the lesion with a high-speed burr ‎and reconstructed the bone defect using iliac crest cancellous ‎graft. More invasive management has been reported by Rao et al 18 using complete surgical excision ‎without grafting. They reported no recurrence at 2 years, yet a persistent bone gap.…”

Introduction Aneurysmal bone cysts (ABC) are expansile, lytic, and benign but locally aggressive lesions. Pelvic ABCs are rare and sometimes difficult to manage surgically. Case Report A 17-year-old female presented with progressive pain and swelling in the right inguinal region. Pelvis radiograph showed a lytic expansile lesion of the superior pubic ramus. A multiloculated cystic lesion was evident on magnetic resonance imaging, and postoperative histopathological evaluation confirmed the diagnosis of ABC. The patient was treated successfully with an intralesional curettage and bone grafting. The postoperative course was uncomplicated with complete healing and no recurrence after 14 months of follow-up. Conclusion ABC of the pubic ramus is a rare entity. Complete intralesional curettage and bone ‎grafting ‎is an effective treatment for pubic ABC. An individualized management approach ‎considering ‎the surgical team expertise, tumor size, and proximity to neighboring structures ‎is recommended.‎.

“…Lesions are typically expansile, eccentric and lytic, with thinning of overlying cortex. A sclerotic rim and internal trabeculation may be present 4,9 . Magnetic resonance imaging may show a well-defined, multiloculated lesion with fluid-fluid levels and contrast enhancing internal septa.…”

“…Histopathologically, ABC is characterised by haemorrhagic, cystic and cavernous spaces surrounded by fibrous septa composed of mild to moderately mitotically active spindle cells intermixed with scattered osteoclast-like multinucleated giant cells. Areas of new and reactive bone formation can also be found 3,9 . Various studies show that the recurrence rate in pelvic ABC is about 14% due to multiple factors, like location of lesion, proximity of neurovascular bundle to the lesion and vulnerability of cartilages of the adjacent joints 3 .…”

Aneurysmal bone cyst (ABC) is a locally destructive lesion of the bone rather than a true neoplasm. The pelvis is not an unusual site for an ABC; approximately 12% of cases occur in this location. We present a case of aneurysmal bone cyst (ABC) in ischiopubic ramus in a 22 years old male who presented with right inguinal swelling and pain. He was evaluated with X-ray and Magnetic Resonance Imaging (MRI) of pelvis. A review of literature regarding this rare site of ABC with radiological features is also described in this case report. ABC of ischiopubic ramus is an uncommon entity hence diagnosis of such a case requires proper clinical, radiological and histopathological evaluation to rule out other differential diagnoses of an expansile, osteolytic lesion. This will help in selecting a proper treatment plan.
