“…A CT scan can also help identify the primary pathology in the appendix by demonstrating its wall thickening and its retrocaecal position. The cystic character of a PMR is best demonstrated by its classic signal characteristics of T1-weighted hypointensity and T2-weighted hyperintensity upon MRI, with enhancement of its wall and thick internal septations upon post-contrast study (3). An MRI accurately maps the extent of the lesion, and helps define its relationship with adjacent structures.…”

A 55-year-old woman presented with a mucopurulent sinusal discharge from the right supragluteal region, with symptoms over the previous five months. This abscess began as a slowly swelling growth, which eventually turned into a discharging sinus, and she was diagnosed with a gluteal abscess. The patient underwent incisional drainage, and intra-operatively, the sinus tract could be seen extending to the retroperitoneum. A subsequent CT scan and an MRI of the abdomen revealed a large heterogeneous retroperitoneal cystic mass on the right side of midline, extending inferiorly into the anterior thigh along the iliopsoas. Superiorly, a tubular projection extended from the lesion, indenting the ileocaecal junction, while a fluid filled cutaneous fistulous tract was seen, extending to the right flank. A diagnosis of pseudomyxoma retroperitonei, likely of retrocaecal appendicular origin, was proposed. An explorative laparotomy with an appendectomy, and the evacuation of the retroperitoneal collection were completed. The subsequent histopathology confirmed the diagnosis of appendicular mucinous cystadenoma, with pseudomyxoma retroperitonei.

“…The most common presentation of PMR is an abdominal mass with pain, while three cases have presented with spontaneous cutaneous fistulae (2)(3)(4), and only a single case exhibited a mass in the anterior thigh region (5).…”

“…Most of this syndrome is mainly attributed to spread from the appendix and rarely from mucinous ovarian neoplasms. Mucocele of the appendix is a rare condition found in 0.2-0.3% of appendicectomies and describes an abnormal mucous deposition in the lumen of the appendix [2]. PMP involving only the retroperitoneum was first described by Bonann in 1948 [3].…”

“…The entity of pseudomyxoma extraperitonei (PME) in which mucinous implants arise in the retroperitoneum without intraperitoneal involvement is even more uncommon. Our literature search revealed only 12 cases of PME that have been reported in the English literature and in almost all the cases, mucinous tumours of the appendix was described as the origin [2]. We report a rare case of PME arising from the ovary and mimicking a psoas abscess.…”

Pseudomyxoma extraperitonei of ovarian origin mimicking a psoas abscess

Pseudomyxoma peritonei (PMP) is a rare condition consisting of mucinous ascites, most commonly arising from mucinous tumours of the appendix and occasionally from the ovary. Very rarely, mucinous deposits arise in the retroperitoneum without intraperitoneal involvement. This has been termed pseudomyxoma extraperitonei (PME). Our 48-year-old female patient presented with PME mimicking a psoas abscess for which retroperitoneal exploration and biopsy was done with accidental breach of the peritoneum. She declined further surgery and re-presented 4 years later with disseminated PMP. She underwent debulking surgery including right oophorectomy which was confirmed as the primary tumour source.

“…6,10,[13][14][15][16][17][18][19][20][21] One can notice that most of these presentations are associated with appendiceal pathology, as well as the male over female predominance (10 to 2). It is interesting to note as well that four of the cases (all are retroperitoneal masses) were not associated with intraperitoneal pseudomyxoma, raising some questions about the real pathogenesis of pseudomyxoma.…”

IA Al-Bozom, Extraperitoneal Presentation of Pseudomyxoma Peritonei as a Scrotal Mass: Case Report and Review of the Literature. 2000; 20(3-4): [297][298][299] Pseudomyxoma is a poorly understood condition which results from implantation of malignant tumors or irritation from ruptured benign cysts.1 Pseudomyxoma peritonei is a form of regional spread of gastrointestinal, gynecological and other malignancies of mucinous nature.2 It is characterized by the accumulation of abundant mucinous material within the peritoneal cavity. The case presented here is unique in that extraperitoneal presentations of pseudomyxoma peritonei are exceedingly rare, and presentation with scrotal mass is even rarer. To the best of my knowledge, there is only one case in the English literature with similar scrotal mass presentation, and 10 other cases with other types of extraperitoneal presentations. Literature review of extraperitoneal presentation of pseudomyxoma peritonei is also discussed. Case ReportA 75-year-old male patient presented to King Khalid University Hospital with nine months' history of left testicular and groin swellings. The patient had a history of right inguinal hernia repair 24 years prior to the recent presentation. Initial examination revealed a normal testis with paratesticular swelling that measured 4.5 cm in diameter, and extended to the spermatic cord, where there was another smaller swelling at the level of the left groin. The swellings were firm, non-tender, irreducible and without cough impulse. Ultrasonography demonstrated the presence of hypoechoic nodules in relation to the epididymis, which focally had a beaded appearance, particularly at the spermatic cord level. There was no focal lesion seen in the testis. His initial workup showed microcytic hypochromic anemia (HB=6.3, MCV=59.7, MCH=17.5, MCHC=29.2), with mild thrombocytosis and ESR value of 66. Total serum iron level was 9 (normal value, 14-32 mmol/L), and TIBC (total iron-binding capacity) value was 40 (normal value, 40-70 mmol/L). The initial clinical impression was tuberculosis of the spermatic cord and testicular adnexa. Surgery was performed after limited anesthesia (spinal anesthesia) due to the poor general condition of the patient. The findings were of inguinal hernia sac communicating with the peritoneal cavity which drained yellowish fluid from the scrotum. Further dissection showed multiple yellow-gelatinous nodules along the spermatic cord and on the outer surface of the testis. Left orchiectomy and repair of the hernia were done.After the histopathology results, a thorough examination of the patient revealed multiple ill-defined paraumbilical swellings that were soft in consistency. Ultrasonography of the abdomen revealed multiple echogenic masses in the peritoneal cavity and multiple echogenic lesions in the liver. Barium enema, and upper and lower gastrointestinal endoscopies were unremarkable. Laparoscopy was performed under spinal anesthesia, and a large appendiceal mass with yellow surface and gelatinous consistency was seen. In...
