A symptomatic cyamella in the popliteus tendon causing snapping knee: a case report and literature review.

ABSTRACT: BACKGROUND:Cyamella,the sesamoid bones of the popliteus muscle, are rare in humans. Snapping knee is an uncommon problem which can be difficult to diagnose. CASE PRESENTATION:In this case, we report a 24-year-old male with snapping knee caused by symptomatic cyamella in the popliteus tendon. A large cyamella was identified upon surgery and was removed. Postoperatively, the patient had immediate relief of preoperative symptoms, and there were no signs of recurrence after 1?years of follow-up. CONCLUSIONS:Although not previously suggested, symptomatic cyamella in the popliteus tendon should be considered as part of the differential diagnosis of the snapping knee.

Graves Disease Causing Pancytopenia: Case Report and Literature Review.

Project description:Graves disease or other causes of thyrotoxicosis are frequently associated with cytopenia. Although anemia is the most common, other cell lineage can be affected. Pancytopenia is a rare complication of thyrotoxicosis.We report a case of a 33-year-old Chinese man who presented a nonsevere pancytopenia in the context of a newly diagnosed Graves disease. Restauration of euthyroid state led to progressive correction of pancytopenia.Literature review shows other rare cases of pancytopenia. It is usually nonsevere with just extremely rare cases of transfusion reported. Evolution was always favorable after achievement of euthyroid state. Its mechanism remains poorly understood, especially because those patients have no vitamin or iron deficiency. The exact physiopathological process remains unclear but 2 causes seem to overlap: reduced production of hematopoietic cells from the bone marrow and increased destruction or sequestration of mature hematopoietic cells. Despite unclear mechanism, the presence of hematologic abnormalities including pancytopenia must not be considered as a contraindication to antithyroid drug therapy.

Rectal foreign body causing perforation: Case report and literature review.

Project description:Background:Clinicians must maintain an index of suspicion to diagnose an anorectal foreign body (FB). The patient may not be forthcoming with information secondary to embarrassment or possibly psychiatric issues. Providers must express empathy and compassion while maintaining nonjudgmental composure. Despite accounts of anal FB insertion, this pathology is lacking level one evidence-based surgical algorithms. Case presentation:A 46-year-old male psychiatric patient presented in septic shock, complaining of lower abdominal/pelvic pain starting 1 week prior. His past medical history was significant for schizophrenia, bipolar disorder, and noncompliance with medications. CT of the abdomen/pelvis revealed a rectal perforation with free air and a FB which appeared to be a screwdriver. Fluid resuscitation and broad-spectrum antibiotics were administered. In the operating room, after unsuccessful transrectal removal, an exploratory laparotomy was performed. The metallic end of the screwdriver had perforated the rectosigmoid. Resection of the perforated rectum with removal of the screwdriver, incision and drainage of a large right buttock abscess and colostomy was performed. The patient recovered and was discharged to behavioral health. At 2 weeks follow-up the patient was doing well with a functioning colostomy and reversal was planned for later this year. Conclusion:This case highlights the importance of maintaining a high index of suspicion when encountering psychiatric patients with nonspecific lower abdominal or anorectal pain with inconsistent presentations. Controversy exists regarding the type of surgical treatment in case of anorectal perforation. More research is needed to provide surgeons with evidence-based standardized methods for dealing with these rare pathologies.

Flexor pollicis longus (FPL) tendon hypoplasia: A case report and literature review.

Project description:An 18-year-old female presented with long-standing inability to flex her left thumb. MRI of the left thumb revealed flexor pollicus longus (FPL) tendon hypoplasia, and subsequent ultrasound of the bilateral thumbs confirmed a left-sided hypoplastic FPL tendon. Structural integrity of the left FPL tendon was confirmed during surgical examination under anesthesia. Multiple congenital anomalies of the FPL have been described, but FPL tendon hypoplasia and its appearance on imaging are rarely reported. This case demonstrates the diagnosis of FPL tendon hypoplasia on MRI, ultrasound, and surgical examination under anesthesia; and demonstrates the importance of including this entity in the differential diagnosis for impaired thumb flexion.

Corynebacterium glucuronolyticum causing genitourinary tract infection: Case report and review of the literature.

Project description:Corynebacterium species are increasingly recognized as opportunistic pathogens. A growing number of taxonomic studies has yielded a description of numerous new Corynebacterium species, such as those related to the urogenital tract, with Corynebacterium glucuronolyticum found to be rarely involved in genitourinary tract infections, particularly in male individuals. In this report, we describe a urethritis case caused by C. glucuronolyticum in a 37-year-old, apparently healthy male, who complained mild pain in the lower abdomen, with several urinary symptoms. While urethral and semen specimens did not yield positive results for microbiological evaluation, cultures of urine samples revealed the monomicrobial growth on blood-containing media of tiny colonies after 24 h of incubation, clearly evident only after 48 h of incubation under CO2-enriched atmosphere. Colonies were identified as C. glucuronolyticum both by matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) and 16S rRNA gene sequencing. Oral ciprofloxacin gradually led to clinical improvement and, finally, to a complete recovery, in accordance with microbiological findings. In spite of its infrequent detection, C. glucuronolyticum might be a potential urogenital pathogen in males more commonly that what believed, perhaps due to slow growth leading to underrecognition; we suggest therefore to consider the organism in the differential diagnostics of bacterial diseases of the urinary tract.

Cleidocranial Dysplasia Causing Respiratory Distress in Neonates: A Case Report and Literature Review.

Project description:Cleidocranial dysplasia (CCD; OMIM 119600) is a rare autosomal dominant skeletal dysplasia, which is mainly characterized by persistently open or delayed closure of fontanelle, patent skull sutures, abnormal clavicles, pectus excavatum, short stature, supernumerary teeth, and sinus and middle ear infections. It is caused by Runt-related transcription factor 2 (RUNX2; OMIM 600211) mutations. Herein, we present a rare case of CCD with neonatal respiratory distress, who had abnormal midfacial features and wide fontanelle. Also, pectus excavatum was noted. He was transferred to our department, administered standard medical treatment, and discharged after 4 weeks. Therefore, we recommend the early suspicion and identification of this rare inherited disease to adequate treatment.

Cervical Synovial Cyst Causing Cervical Radiculomyelopathy: Case Report and Review of the Literature.

Project description:Study Design Case report. Objective Synovial cysts in the subaxial cervical spine are rare and are most commonly reported at the cervicothoracic junction. Only six cases of symptomatic C5-C6 synovial cysts have been reported in the literature; the condition is usually treated with decompressive laminectomy. We present a patient with a synovial cyst arising from the C5-C6 facet joint, associated with spondylolisthesis, and causing radiculomyelopathy. The patient was treated with a posterior excision of the cyst, decompressive laminectomy, and fusion. Methods A 67-year-old man had vertebral canal stenosis at C5-C6 secondary to a synovial cyst and spondylolisthesis with symptoms and signs of radiculopathy and myelopathy. Surgical management involved C5-C6 posterior decompressive laminectomy and excision of the cyst and C4-C6 instrumented fusion with lateral mass screws and rods. A literature review of symptomatic cervical synovial cysts is presented. Results The imaging studies identified grade I spondylolisthesis and a 3.3 × 4.3-mm extradural lentiform-like mass associated with focal compression of the spinal cord and exiting the C6 nerve root. After the surgery, the patient had an immediate full recovery and was asymptomatic by the 6-month examination. No operative complications were reported. The histologic report confirmed the presence of a synovial cyst. Conclusions C5-C6 is an unusual localization for symptomatic synovial cysts. Similar cases reported in the literature achieved excellent results after cyst excision and decompressive laminectomy. Because spondylolisthesis plus laminectomy are risk factors for segmental instability in the cervical spine, we report a case of a C5-C6 facet synovial cyst successfully treated with posterior laminectomy and C4-C6 fusion.

Snapping Plantaris Tendon: A Rare Case in a Competitive Dancer.

Project description:Pathology associated with the plantaris includes rupture of the tendon and an association with mid-substance Achilles tendinopathy in some patients. There have only been two previous case reports in the literature in English language describing snapping of the plantaris tendon. We present a case report of a 15-year-old female competitive dancer who described pain and an audible popping at the medial margin of the Achilles tendon while squatting. Physical examination revealed visible and audible popping of the plantaris, and ultrasonography confirmed the diagnosis. After symptoms persisted despite nonsurgical treatment with physical therapy, the patient underwent an open plantaris tenotomy. By 8 weeks after surgery, she had resumed dancing. Twenty-three months after her operation, she reported an excellent outcome and full recovery with no limitations to her physical activity. She reported having no pain, a Foot and Ankle Ability Measure Activities of Daily Living Subscale score of 100, and a Foot and Ankle Ability Measure Sports Subscale score of 100. This case demonstrates a successful course of treatment for this uncommon pathology within the context of a competitive dancer.

Recurrent symptomatic vertebral hemangioma during two consecutive pregnancies: Case report and review of the literature.

Project description:Pregnancy-related changes can exacerbate the symptoms/signs of vertebral hemangiomas. Here, we report a patient who experienced symptomatic vertebral hemangiomas resulting in cord compression during two consecutive pregnancies.A 28-year-old female 34 weeks pregnant, presented with a progressive spastic paraparesis. Magnetic Resonance Imaging (MRI) demonstrated an T5 vertebral body signal change attributed to a hemangioma resulting in cord compression. Following a cesarean section, she had a trans thoracic T5 corpectomy with spinal fusion. Indeed, the histopathology was consistent with a vertebral hemangioma. She fully recovered after this first surgery. However, six years later, she again presented with a spastic paraparesis and sphincter deficit now 29 weeks pregnant. The MR demonstrated cord compression one more at the T5 level attributed to the hemangioma; following a T5 and T6 laminectomy, the left paracentral epidural vascular mass totally resected. Her child was successfully delivered 2 months later at which point she exhibited only mild residual lower limb spasticity.Patients with known vertebral hemangiomas should be closely monitored during pregnancy as increased growth during these pregnancies may result in progressive spinal cord compression.
