OBJECTIVE:
To precise classify sacral meningeal cysts, effective guide minimally invasive neurosurgery and postoperative personalized rehabilitation by multiple dimensions radiographic reconstruction MRI.
METHODS:
From March to December 2021, based on the original 3D-fast imaging employing steadystate acquisition (FIESTA) scanning sequence, 92 patients with sacral meningeal cysts were pre-operatively evaluated by multiple dimensional reconstruction MRI. The shape of nerve root and the leakage of cyst were reconstructed according to the direction of nerve root or leakage track showed on original MRI scans. Sacral canal cysts were accurately classified as including nerve root and without nerve root, so as to accurately design the incision of skin and formulate corresponding open range of the posterior wall of the sacral canal. Under the microscope intraoperation, the shape of the nerve roots inside cysts or leakage track of the cysts without nerve roots were verified and explored. After the reinforcement and shaping operation, several reexaminations of multiple dimensional reconstruction MRI were performed to understand the deformation of the nerve root and hydrops in the operation cavity, so as to formulate a persona-lized rehabilitation plan for the patients.
RESULTS:
Among the 92 patients with sacral mengingeal cyst, 58 (63.0%) cysts with nerve root cyst, 29 (31.5%) cysts without nerve root cyst, and 5 (5.4%) cysts with mixed sacral canal cyst. In 58 patients with nerve root cysts, the accuracy of preoperative clinical classification on MRI image reached 96.6% (56/58) through confirmation by operating microscope. Only 2 cases of large single cyst with nerve root on the head of cyst were mistaken for without nerve root type. In 29 patients with sacral cyst without nerve root, the accuracy of preoperative image reached 100% through confirmation by operating microscope. The accuracy of judging the internal nerve root and leakage of 12 cases with recurrent sacral cyst was also 100%. Two cases of delayed postoperative hydrops were found one month after operation. After rehabilitation treatment by moxibustion and bathing, the hydrops disappeared 4-6 months after operation.
CONCLUSION
Multiple dimensional reconstruction MRI can precisely make clinical classification of sacral meningeal cysts before operation, guide minimally invasive neurosurgery effectively, and improve the rehabilitation effect.

OBJECTIVES:
This study aims to evaluate the changes in the mandibular canal following the treatment of large odontogenic keratocysts through decompression and curettage, providing a theoretical basis for sequential treatment.
METHODS:
Twenty patients were selected for each decompression and curettage treatment of large odontogenic keratocysts in the mandible. Postoperative follow-up with was conducted every three months, during which cone beam computed tomography (CBCT) scans were performed. Then, the data were imported into MIMICS software to observe 3D changes in the position and structure of the mandibular nerve canal, followed by a comparative analysis.
RESULTS:
The total displacement of the mandibular canal was (1.89±0.21) mm on the decompression side and (0.80±0.19) mm on the curettage side. Vertically, the displacement range of the mandibular canal on the decompression side (M=1.03, SD=0.17) was larger than on the curettage side (M=0.52, SD=0.010) within nine months post-operation. In the buccal-lingual direction, the ratio of the thickness of the buccal plate to the lingual plate gradually increased with time. The amount of bone reconstruction at the part of the mandibular nerve canal closest to the cyst was (1.75±0.15) mm on the decompression side and (1.45±0.09) mm on the curettage side after nine months.
CONCLUSIONS
The mandibular nerve canal showed varying degrees of recovery and "relocation" after two surgical procedures. Osteogenesis around the mandibular nerve canal was more remarkable after decompression than after curettage. Therefore, for large odontogenic keratocyst, decompression is recommended as the initial treatment, followed by secondary curettage nine months later.

ObjectiveTo investigate the diagnosis and treatment of ejaculatory duct cyst.
METHODSThis study included 2 male patients present at the hospital for hemospermia and abnormal sensation in the perineal region in July and August 2014. Both underwent transrectal ultrasonography, routine semen examination, CT, MRI, cystoscopy, and vesiculography before transurethral fenestration of the cysts and pathological examination of the cyst wall specimens. Analyses were made on the clinical presentations, imaging features, pathological characteristics, differential diagnosis and treatment of ejaculatory duct cyst and relevant literature was reviewed.
RESULTSThe cyst wall was mainly composed of smooth muscle, the inner wall lined with pseudostratified ciliated columnar epithelia, and with positive expressions of CD10 and Muc6 proteins on immunohistochemical staining, which indicated renal iatrogenic ejaculatory duct cyst. The patients were followed up for 18 and 20 months, respectively. All symptoms disappeared and no recurrence occurred after surgery. Routine semen examination for the two patients showed the semen volumes to be 3.5 and 3.1 ml, sperm concentrations 35 and 32 ×10⁶/ml, grade a sperm 32.0 and 26.0%, grade b sperm 18.0 and 31.0%, and semen liquidation time 30 and 34 minutes, respectively.
CONCLUSIONSPelvic cystic masses can be detected by transrectal ultrasonography, CT and MRI, but definite diagnosis relies on vesiculography, pathological examination and immunohistochemical staining. Transurethral fenestration is safe and effective for the treatment of ejaculation duct cyst.

Objective:
To investigate the success rate and safety of percutaneous vasoseminal vesiculography with the disposable vasographic interventional therapy kit (VITK).
METHODS:
This study included ninety-six 19-65 (mean 43) years old male patients with infertility, hematospermia, seminal vesicle cyst, ejaculatory duct cyst, ejaculatory dysfunction, or vas deferens injury, with disease courses varying from 1 month to 7 years. With an open, multi-centered, single-group, self-controlled design and using the disposable VITK, we treated the patients by percutaneous vasoseminal vesiculography via injection of contrast medium into the vas deferens cavity under local anesthesia.
RESULTS:
Percutaneous vasoseminal vesiculography was successfully performed in 92 (97.87%) of the patients, which revealed abnormal seminal ducts in 51 cases (54.3%). Among the 28 infertile patients, 3 were found with bilateral and 5 with unilateral vas deferens obstruction. Vesiculitis was detected in 36 (81.8%) of the 44 hematospermia patients and bilateral vas deferens abnormality in 5 (38.5%) of the 13 patients with ejaculatory dysfunction. Transectional damage was observed in 2 patients with vas deferens injury induced by bilateral inguinal hernia repair. Three cases of seminal vesicle cyst and 4 cases of ejaculatory cyst were definitely diagnosed by vasoseminal vesiculography.
CONCLUSIONS
The disposable vasographic interventional therapy kit, with the advantages of simple operation and high safety, deserves a wide clinical application in vasoseminal vesiculography.

Congenital cysts of the gallbladder are extremely rare, hence only a few ciliated foregut cysts of gallbladder have been reported. We report a case of a 20-year-old woman presenting with mild right upper quadrant abdominal discomfort, with normal levels of serum bilirubin and liver function tests. Abdominal ultrasonography revealed a well-defined cystic mass measured about 2 cm attached to the neck of gallbladder, with internal echogenic debris suggesting a complicated cyst, such as a hemorrhagic cyst. Abdominal computed tomography and magnetic resonance cholangiopancreatography revealed similar findings. Laparoscopic cholecystectomy showed a slightly distended gallbladder. The size of cyst on the neck was 1.6x1.2 cm, and it contained mucosa lined by ciliated pseudostratified columnar epithelium and underlying smooth muscle layers. Histopathology identified a ciliated foregut cyst of gallbladder.

Intraosseous ganglion cyst of the carpal bones represents a rare cause of wrist pain. We report a case of a 42 year-old, right-handed female, who presented with pain of the right wrist following a fall on the palm of the hand. Clinical study revealed a moderate swelling over the mid-section of the palmar face and pain through extreme ranges of motion of the wrist. Plain radiographs and CT-scan of the wrist have revealed an intraosseous ganglion cyst of the lunate bone. Curetting-filling by Kuhlman's vascularized radial bone graft allowed a good functional recovery. The clinical, radiological and therapeutic aspects are discussed.

INTRODUCTIONEndoscopic transenteric stenting is the standard treatment for pseudocysts, but it may be inadequate for treating infected collections with solid debris. Surgical necrosectomy results in significant morbidity. Direct endoscopic necrosectomy (DEN), a minimally invasive treatment, may be a viable option. This study examined the efficacy and safety of DEN for the treatment of infected walled-off pancreatic necrosis and infected pseudocysts with solid debris.
METHODSThis study was a retrospective analysis of data collected from a prospective database of patients who underwent DEN in the presence of infected walled-off pancreatic necrosis or infected pseudocysts with solid debris from April 2007 to October 2011. DEN was performed as a staged procedure. Endoscopic ultrasonography-guided transgastric stenting was performed during the first session for initial drainage and to establish endoscopic access to the infected collection. In the second session, the drainage tract was dilated endoscopically to allow transgastric passage of an endoscope for endoscopic necrosectomy. Outcome data included technical success, clinical success and complication rates.
RESULTSEight patients with infected walled-off pancreatic necrosis or infected pseudocysts with solid debris (mean size 12.5 cm; range 7.8-17.2 cm) underwent DEN. Underlying aetiologies included severe acute pancreatitis (n = 6) and post-pancreatic surgery (n = 2). DEN was technically successful in all patients. Clinical resolution was achieved in seven patients. One patient with recurrent collection opted for surgery instead of repeat endotherapy. No procedural complications were encountered.
CONCLUSIONDEN is a safe and effective minimally invasive treatment for infected walled-off pancreatic necrosis and infected pseudocysts.
