Anterior Sacral Meningocele

Introduction. Anterior sacral meningocele (ASM) is a very rare condition that is the herniation of the meningeal sac into the pelvic cavity through a developmental bone defect of the anterior wall of the sacrum. Most of the ASM are diagnosed in childhood but the reported cases that are diagnosed in adults exhibit a gamut of complications. Case report. We presented a case of ASM excision that was misdiagnosed as a giant ovarian cyst. A 28-year-old woman was admitted to the General Surgery Clinic and than to the Gynecology Department with suspect of ovarian cyst depending on ultrasonography (US) scans solely. Adnexial torsion was suspected and surgery to remove the cyst and adnexial exploration was planned. When the lesion was found out to be ASM, neurosurgery team tied the neck and excised the whole meningocele. Histopathologic evaluations confirmed dural sac. Neurological examinations right after the operation revealed 20% weakness in knee extension. It totally recovered in 6 months time. Her MR imaging studies and computed tomography (CT) scans revealed multiple ASM sacs and defects of the anterior wall of the sacrum. Conclusion. This case emphasizes the importance of utilizing available screening tools including CT andmagnetic resonance imaging (MRI) studies as the gold standard in addition to US scans in the preoperative period in order to accurately evaluate and characterize any pelvic lesion.

Dural Sinus Malformation

Dural sinus malformation is a rare condition. We describe a prenatally detected case followed by repeated ultrasound scans and a prenatal magnetic resonance imaging examination. A substantial spontaneous regression was observed, which is associated with a favorable outcome. We believe that our observations, including a long postnatal follow-up, will add to the present knowledge of prenatally detected cases, and thus improve management of the pregnancies as well as our possibilities to counsel the parents-to-be.

Aneurysmal Bone Cysts

PurposeWe have reviewed a series of 150 aneurysmal bone cysts treated over the last 20 years.Patients and MethodsThe lesions were principally located in the tibia, femur, pelvis, humerus, and spine and, in most cases, presented the imaging appearance originally described by Jaffe and Lichtenstein as a blowout with thin cortices.ResultsOnly one of the patients was believed to have an osteoblastoma of the spine with secondary development of an aneurysmal bone cyst, and none of the patients developed additional lesions. The patients were treated primarily with curettage and implantation of allograft chips or polymethylmethacrylate, but some patients were treated with insertion of autografts or allografts. The local recurrence rate was 20%, which is consistent with that reported by other centers.ConclusionAneurysmal bone cysts are enigmatic lesions of unknown cause and presentation and are difficult to distinguish from other lesions. Overall, the treatment is satisfactory, but it is possible that newer approaches, such as improved magnetic resonance imaging studies, may help diagnose the lesions and allow the physicians to plan for more effective treatment protocols.

AbstractObjectives:We report a case of otogenic fungal pachymeningitis in a diabetic patient who presented with multiple cranial nerve palsies and nasopharyngeal swelling.Methods:We present a case report, we describe the investigations, management and clinical course of fungal pachymeningitis, and we present a review of the world literature on fungal and non-fungal pachymeningitis.Results:To our knowledge, this is the first report of fungal pachymeningitis with magnetic resonance imaging features suggestive of nasopharyngeal carcinoma. It is also the first reported case with aspergillus cultured from both a dural biopsy and the ear canal.Conclusion:Fungal pachymeningitis is a rare condition which may present to otorhinolaryngologists. Its clinical and radiological findings can be confused with those of nasopharyngeal carcinoma; fungal pachymeningitis should thus be included in the differential diagnosis of nasopharyngeal carcinoma.

Objectives: Muscle hypertrophy is a relatively rare condition that may cause nerve entrapment syndromes. We report the case of a 14-year-old girl with unilateral hypertrophy of the abductor hallucis muscle with entrapment of the medial plantar nerve and review the literature. Methods: Computed tomography and magnetic resonance imaging revealed unilateral hypertrophy of the abductor hallucis muscle. Results: Two injections of steroid and lidocaine at the point of tenderness resulted in resolution of the pain. Conclusions: We report a rare case of hypertrophy of the abductor hallucis muscle considered with entrapment of the medial plantar nerve. Treatment of this condition should be selected according to the pathological condition of each patient.
