Calvarial tuberculosis.

BACKGROUND: Calvarial tuberculosis is rare, even in areas where tuberculosis is endemic. Primary calvarial tuberculosis, with no evidence of tuberculosis elsewhere in the body is a rarer entity. METHODS: Seven cases of calvarial tuberculosis are presented. The relevant clinicoradiological features and management are discussed. RESULTS: Two cases of primary calvarial tuberculosis could only be diagnosed after surgery. The other cases were diagnosed with the help of fine needle aspiration cytology (FNAC) and biopsy. CONCLUSION: A high index of suspicion and awareness of this condition may lead to more cases being diagnosed early. Surgery may be avoided in selected cases that can be treated primarily with antitubercular therapy.

Maxillofacial cysticercosis: uncommon appearance of a common disease.

OBJECTIVE: To highlight the sonographic appearances of cysticercosis involving uncommon muscular sites. METHODS: Two patients with nodular swelling involving the tongue and maxillary region were examined with high-resolution sonography. RESULTS: Sonographic examination revealed an anechoic area with a small calcified scolex suggesting cysticercus infection. CONCLUSIONS: High-resolution sonography is a noninvasive and nonionizing imaging modality that plays an important role in establishing the diagnosis of cysticercosis.

Comparative analysis of duodenal biopsy tissue orientation supported on vegetable matrix versus filter paper.

BACKGROUND: Biopsy tissue may get disoriented if filter paper is used as a supporting medium. Use of vegetable matrix (cucumber) as a supporting medium may obviate the need of lifting the tissue while making blocks and thus avoid disorientation that occurs during this step. OBJECTIVE: To compare the orientation of duodenal biopsy tissue supported on vegetable matrix (cucumber) and on filter paper. METHODS: Over one year, 40 patients (20 with large-volume diarrhea, 20 with dyspepsia) were included in the study. Two pairs of duodenal biopsy tissues were obtained during gastroscopy; one pair was placed on filter paper, the other on vegetable matrix. Tissue and vegetable matrix were embedded together while making blocks, whereas the tissue had to be lifted off in case of filter paper. Sections were stained and assessed for crypt-villous alignment, parallel orientation of crypts and presence of visible muscularis mucosae with the help of a scoring system. RESULTS: Compared to biopsy tissue supported on filter paper, vegetable matrix-supported tissues were better oriented. Scores were rated as bad, good and very good in 8, 11 and 21 vegetable matrix-mounted tissues and in 21, 11 and 8 filter paper-mounted tissues, respectively. CONCLUSION: Duodenal biopsy tissue supported on vegetable matrix (cucumber) is better oriented than that on filter paper.
