Solitary fibrous tumours are rare mesenchymal tumours which mostly arise from pleura. Such tumours occurring in the mesocolon are exceptionally rare. A 35-year-old man was referred to the general surgery department with a painless and nonpalpable mass in the right quadrant of the abdomen, which was detected incidentally on magnetic resonance imaging. The patient had no symptoms and the physical examination revealed no findings. The patient underwent surgical resection and excisional biopsy results revealed an intra-abdominal solitary fibrous tumour originating from the ascending mesocolon. He was discharged two days after surgery and remained disease-free at the end of the two-month follow-up period.

We report a case of a 40-year-old woman with synovial sarcoma who presented with neural symptoms in the medial aspect of the right foot and ankle. The radiographic appearance of the foot and ankle was unremarkable, but magnetic resonance imaging showed a relatively well-defined enhancing lesion in the plantar soft tissues extending from the master knot of Henry to the posterior tibialis tendon. After orthopedic oncologic evaluation and workup, the patient was ultimately treated with a transtibial amputation, and no evidence of recurrence or metastatic disease was seen at 6-month follow-up.

Background: Alcohol dependence (AD) is a chronic recurrent brain disease that causes a heavy disease burden worldwide, partly due to high relapse rates after detoxification. Verified biomarkers are not available for AD and its relapse, although the nucleus accumbens (NAc) and medial prefrontal cortex (mPFC) may play important roles in the mechanism of addiction. This study investigated AD- and relapse-associated functional connectivity (FC) of the NAc and mPFC with other brain regions during early abstinence.Methods: Sixty-eight hospitalized early-abstinence AD male patients and 68 age- and education-matched healthy controls (HCs) underwent resting-functional magnetic resonance imaging (r-fMRI). Using the NAc and mPFC as seeds, we calculated changes in FC between the seeds and other brain regions. Over a follow-up period of 6 months, patients were measured with the Alcohol Use Disorder Identification Test (AUDIT) scale to identify relapse outcomes (AUDIT ≥ 8).Results: Thirty-five (52.24%) of the AD patients relapsed during the follow-up period. AD displayed lower FC of the left fusiform, bilateral temporal superior and right postcentral regions with the NAc and lower FC of the right temporal inferior, bilateral temporal superior, and left cingulate anterior regions with the mPFC compared to controls. Among these FC changes, lower FC between the NAc and left fusiform, lower FC between the mPFC and left cingulate anterior cortex, and smoking status were independently associated with AD. Subjects in relapse exhibited lower FC of the right cingulate anterior cortex with NAc and of the left calcarine sulcus with mPFC compared to non-relapsed subjects; both of these reductions in FC independently predicted relapse. Additionally, FC between the mPFC and right frontal superior gyrus, as well as years of education, independently predicted relapse severity.Conclusion: This study found that values of FC between selected seeds (i.e., the NAc and the mPFC) and some other reward- and/or impulse-control-related brain regions were associated with AD and relapse; these FC values could be potential biomarkers of AD or for prediction of relapse. These findings may help to guide further research on the neurobiology of AD and other addictive disorders.

The multiseptate bladder is a congenital bladder anomaly that is very rare and often accompanied by other congenital abnormalities. This condition could result in intravesical obstruction and kidney failure in more serious conditions. A 3-year-old girl without any complaint was consulted by the Pediatric Surgery Department with postoperative cloacal type malformation anorectal (MAR) postero-sagittal anorecto-vagino-urethroplasty (PSARVUP) + sigmoidectomy. Magnetic Resonance Imaging (MRI) of the pelvis showed the appearance of four interconnected multiple fluid lesions. Cystoscopy was performed and found many septa with varied positions and forms. From the cystography during the operation, it was seen duplication of the right and left bladder. There was no further operative treatment in the field of urology because no urinary tract obstruction and normal renal function were found in this study.

Mesenchymal Tumours

Angiomyolipomas are benign mesenchymal tumours originating from the kidney and adrenals. They are rare tumours that can be sporadic and isolated or occur as a part of tuberous sclerosis. These tumours have a high content in the cells, which is pathognomonic for diagnosis using ultrasonography, computed tomography and magnetic resonance imaging. Atypical angiomyolipomas occur with excessive smooth muscle cells and less adipose tissue, and are sensitive to immunohistochemistry studies. Most of these lesions are detected incidentally but some can cause back and abdominal pains if large in size. Larger lesions are also vulnerable to spontaneous or traumatic rupture, causing large retropertitoneal bleeds. Surgery should be considered as the definitive management for larger lesions to avoid associated complications. There have been no reports of any malignant change being reported in any of the lesions but a long follow-up period is still required, given the unknown clinical progression of these rare tumours.

Mesenchymal Tumours

Solitary fibrous tumours (SFTs) are unusual mesenchymal tumours that were first described as primary spindle-cell neoplasms of the pleura. These tumours have been described in many other locations, including the urogenital system, orbit, mediastinum, and upper respiratory tract. These tumours are generally benign in nature, however some of them can be locally invasive and have the potential to be malignant. Although about 12%-15% of them occur in the head and neck area, SFT of the nasal cavity and paranasal sinuses are extremely rare. We present a case of a solitary fibrous tumour arising from the right maxillary sinus in a 50-year-old Chinese man.

A 40-year-old right-handed man sought care for right hand numbness, right-sided facial numbness, and diplopia progressing to maximal severity over 10 days. At his worst he was unable to write. His symptoms remained maximal for 4 weeks. He was hospitalized and treated with 5 days of intravenous methylprednisolone. He improved to approximately 95% of normal over 4 weeks. He had residual mild right-sided facial and right leg numbness. Antibodies to JC polyoma virus and varicella-zoster virus were positive, which indicated prior exposure to these viruses. Total 25-hydroxyvitamin D level was low at 8.2 ng/mL. Optical coherence tomography findings were normal. Magnetic resonance imaging of the brain performed 3 months after the onset of symptoms demonstrated a T2-hyperintense lesion in the left midbrain peduncle extending into the upper pons, without gadolinium enhancement. A small area of T2 hyperintensity was seen in the right frontal deep white matter. Follow-up brain magnetic resonance imaging showed almost complete resolution of the left midbrain peduncle lesion with persistence of the right frontal deep white matter lesion. Spinal fluid analysis showed 1 white blood cell/µL with 95% lymphocytes, protein 35 mg/dL, 0 unique oligoclonal bands, and normal immunoglobulin G index (0.54). A diagnosis of clinically isolated syndrome-first episode of multiple sclerosis was made. After detailed discussion with the patient, he elected to commence disease-modifying therapy with fingolimod. He underwent routine monitoring with magnetic resonance imaging of the brain and cervical and thoracic spine on an annual basis, without any further relapses at 5-year follow-up. Patients with typical demyelinating syndromes may not always fulfill the diagnostic criteria for multiple sclerosis. After careful exclusion of other mimicking conditions, most notably aquaporin-4-immunoglobulin G– and myelin oligodendrocyte glycoprotein-immunoglobulin G–associated disease, a diagnosis of clinically isolated syndrome may be made.

We present a 10-year old boy with recurrent swelling of the right mandibular region. Based on the diagnosis of chronic recurrent parotitis, he received only supportive treatment. Because of frequent relapses, the diagnosis was reconsidered. Magnetic resonance imaging, scintigraphy and biopsy were compatible with chronic osteomyelitis. This lead to a diagnosis of mandibular primary chronic osteomyelitis, an uncommon non-suppurative inflammatory disease of unknown origin. After decortication of the mandible, the patient recovered well. Because there were no further complaints, the follow-up was ended 18 months after the operation.

A 16-month-old male with previously untreated bilateral clubfeet was admitted to S.B. Izmir Tepecik Education and Research Hospital, Izmir, Turkey. Both feet underwent surgical treatment. During surgery, an accessory soleus muscle was detected on the right side. The accessory soleus muscle had a distinct distal insertion at the superior anteromedial border of the calcaneus and also anterior and medial to the Achilles tendon. He was treated by bilateral complete subtalar release with Cincinnati incision, and the accessory soleus was also cut and the distal part resected. At the final follow-up visit, when the patient was 6 years and 9 months old, both feet had a normal appearance and appeared normal on radiograph and magnetic resonance imaging, with no presence of the accessory soleus muscle or its remnant. In our opinion, awareness of the association between an accessory soleus muscle and clubfoot, and sectioning of this muscle during surgery may improve surgical results.
